The British Geological Survey(bgs) is 'Building a Future for Rocks' lecture at the Geological Society of London earlier this month (October) had strong hopes of opening up new avenues of communication. Balance between different bgs building stone needs. Information about the stones used in the construction of the heritage of the British Isles is not easy to find. Some recoveries are not stored in any form of system, and they are also very difficult to find, often incomplete and sometimes very inaccurate. There is no national database available to identify batteries used in households and link that information to the sources of those batteries. More information is available - for example, English Heritage has records of 370,000 listed buildings in England, most of which are shown on the website www.imagesofengland.org.uk, but there is little information specifically on the building materials used. Creating a database that brings all this information together, at least for England, is why English Heritage is working with the British Geological Society (BGS) on the Strategic Stone Study. And the BGS wants to expand even further, becoming a hub for information about the different soil uses of the British Isles and for building Britain's great heritage and special language. A step towards this goal was taken earlier this month (October) when the BGS held a groundbreaking meeting at the Geological Society's headquarters in London. He invited planners, architects, masons, conservators and others interested in the use of stone to the forum to introduce and discuss key issues in heritage and new construction. In addition to the Strategic Stone Study, those involved in similar stonework in Scotland, Wales and Northern Ireland also reported on their projects and the Geological Survey of Belgium gave their views on the matter. Although the special lecture included many people from all walks of life, less than 100 people came to hear the presentations. , which emphasizes the problem – communication. Various interested parties receive money from various sources to carry out their specialized research without reference to other work done by other organizations in the same field, usually in the belief that their work is unrelated to disruption and other work.

The result can be duplication of effort and inconsistent results. Businesses would be better served if BGS could centralize all the information they wanted and make it easy to find and reference information. The next step on this path coincided with an announcement in London - the transfer of 2,500 specimens from the Natural History Museum's rock collection to the BGS on long-term loan. The collection will now be housed at BGS in Nottingham, bringing the museum's collection to 20,000 examples of building stone. Well, part of its appeal is to help those looking to match newly excavated rocks to native rocks. There are other stone plaques and the survey wants to document them all. Some like Sedgwick and Brunel were mentioned during the lecture. Anyone with information on other collections is invited to contact BGS. BGS's Graham Lott told the conference: “I'm very interested in collections like ours. This is not only important for historic buildings, but the use of traditional stone in new construction should be encouraged. He also appealed to inform the inquiry if there are records of work on historical stone structures. And when a battery is replaced at home and the old battery is thrown away, he said research wants to retrieve that battery. His aim has always been to tie up with the quarries that supply the stone so that people understand the importance of mining. He hopes the information the BGS wants to make available will encourage artists to come to Nottingham and see the collection of stones. "There is no substitute for seeing it." Evan Hyslop, project manager for stone research and consultancy at BGS in Edinburgh, showed some interesting pictures of what happens when restoration is done with stones that don't match the original shape or functionality. In some cases the use of less porous stone for restoration has significantly reduced the erosion of the original stone as there are good records of the use of cement mortar. The modern stone supply industry and the heritage sector, as keynote speaker James Simpson of Simpson & Brown Architects in Edinburgh said: “I believe we have now reached a point where we see modern building and traditional building as two very different things. should be thought of as James, who was made an OBE for services to the built environment in 2007, pointed out the difference between traditional and modern construction: traditional buildings use local, minimally processed materials resulting in less Carbon footprints were weak, permeable and flexible. There is no new construction. He said that it is important to train both and provide both.

In those days stone was just a decorative finish. There was nothing wrong with that and the stone supply industry had to be prepared to supply the necessary components. But it also had to provide the local stone needed to maintain the folk traditions of the existing building stock. It is generally accepted that maintenance of existing buildings is a greener alternative to new construction and that only the useful and meaningful should be considered. As for training, James said today's courses might be admirable for teaching people how to work on new construction, but were "completely useless" when it came to traditional building. He called for a return to traditional apprenticeship. The full proceedings of the symposium were recorded and will eventually be available for free download from the BGS website. Great Britain's long and complex geological history has produced a very diverse range of rock types, many of which have been quarried for construction purposes over the centuries. Some of the most famous building stone quarries in the country have been in continuous operation since the earliest times. Many, however, are long closed and their stones are no longer available. The original source of the mines is often difficult to trace because the land surface is gradually changing due to the development of agriculture and the expansion of cities, towns and villages. Finding suitable stone for the conservation and repair of historic churches and other buildings can be difficult, and as with many other aspects of conservation, the field of professional expertise is growing. However, it is important that anyone involved in the maintenance and upkeep of our buildings or monuments should be aware, even at a basic level, of the procedures professionals are likely to follow. Some areas of this business are best left to professionals, while others require more detailed study and a little detective work can be informative fun. From quartz, feldspar and smaller rock fragments. Their high quartz content makes them a hard, durable building stone. By measuring the average grain size, sandstones can be divided into fine, medium and coarse types. Some sandstones can be distinguished by the presence of characteristic mineral elements, at least on a regional scale. Two examples of this are the Lower Cretaceous sandstones of south-east England, which commonly contain the green mineral glauconite, and the very fine-grained Triassic sandstones of the East Midlands, known locally as 'skerries', which are commonly cemented. Dolomite 
building stone steps
Different types of limestone are used as building stone. They are composed primarily of calcium carbonate (calcite) and are relatively soft compared to most sandstones. Their soft nature allows them to be easily cut and they are our best loose stones. Most limestones are formed by the accumulation of broken shells of marine organisms on the sea floor in tropical or subtropical environments. Good examples include Clipsham and Ancaster stones. In coarse limestone, fragments of fossilized shells are easily visible with the naked eye. A fine example of fine-grained limestone is the white chalk of southern and eastern England. It consists entirely of calcite skeletons of microscopic organisms known as coccoliths. A special group of limestones which form perhaps our most famous building stone are the oolitic limestones of the Bath and Portland quarries. It formed on the sea floor as a concentration of millimeter-sized spherical oolites. Their characteristic spherical shape and concentrically laminated structure developed when microscopic algae deposited successive layers of calcium carbonate around a small core, which may be a shell fragment or a quartz grain. In some limestones, the fossils they contain can be identified enough by experts to determine which quarry they came from. This group of rocks also includes magnesium-rich limestones or dolomites. Dolomites are formed by chemical alteration of original calcium-rich limestone. This alteration process can completely destroy or preserve the original scaly limestone fabric to form crystalline stones. Well-known dolomitic building stones include the Mansfield, Cadeby and Tadcaster limestones. An important characteristic of sedimentary rocks is their porosity. Pores are natural openings in rock that allow fluids such as rainwater to enter and leave the fabric. Some flow of free fluid through the rock is necessary to maintain the durability of the rock, and it is not always advisable to prevent such flow by using the wrong mortar mix or by injecting an inappropriate artificial fluid. However, too high a porosity can allow excessive amounts of corrosive fluids such as acid rainwater to enter and seriously damage the rock. Thin-section analysis can identify where such problems are likely to occur. Most durable silt building stones generally have moderate porosity. A third group of rocks are metamorphic rocks formed by the alteration of other types of rock by heat and pressure. They exhibit some of the characteristics of both igneous and sedimentary rocks, often having a hard, crystalline structure, but retaining traces of the original surface of the sedimentary layer. Metamorphic rocks are not widely used as building stones, but are the main source of roofing slate in the UK. Such shells are still mined from older metamorphic rocks in North Wales, Cornwall and Cumbria. Important slate industries in Leicestershire (Switzerland) and throughout Scotland have long since ceased or been greatly reduced. 
Shales are formed by the recrystallization of fine-grained sedimentary or igneous rocks under extreme temperatures and pressures. Under such conditions, which develop over millions of years, new minerals (mainly mica) grow and characteristic shale splitting occurs. The alignment of these new minerals allows the shale to be easily split into thin sheets. An important characteristic of metamorphic shales is their lack of porosity, which makes them impermeable to fluid flow. The so-called shales are not metamorphic shales but rather thinly layered silty limestones and sandstones that are naturally divided into thin layers or slabs. Metamorphic rocks are also true marble. Geologists apply this term only to limestone that has been metamorphosed. Metamorphic limestones show a very different texture from the parent rock, but mineralogically they are still mainly composed of calcium or magnesium carbonate. One thing you can be sure of is that if you have identified a marble transformed into a buoy Iron The most important source of information in this area is the British Geological Survey (BGS) as it maintains a comprehensive archive of British building stone geology. After its establishment in 1839, one of the first commissions of the BGS was to find suitable building stone for the construction of the new building of the Palace of Westminster in 1839. Since then the BGS has documented over 1,000 building and decorative stones quarried and used in Britain and has undertaken to collect representative samples from working quarries. The Institute now maintains the country's most comprehensive database of geological maps, specimens and archives. This data set is used in a wide range of applied geological investigations including the procurement of building stones. When considering a building or monument, the criteria for acquiring new stone can be considered under the following headings: stone identification, source and matching. Identification of stones All natural stones are classified into one of three groups of rocks - igneous, sedimentary or metamorphic. Rocks are hard and crystalline and make up the basic material of the Earth. They are formed directly by the cooling of hot molten magma. The most famous igneous rock used for construction or monumental purposes is probably granite. Granites are coarse-grained rocks containing large crystals of vitreous quartz, opaque white or pink feldspars, and dark brown or black ferromagnesian minerals (mica, hornblende, etc.) easily discernible with the naked eye. 
The coarse nature of the crystals tells us that the rock was formed from magma that cooled too slowly in the Earth's crust to allow individual crystals to grow to large sizes. Some well-known granites include Cumbrian Shap with large pink feldspar and Cornish de Lanc with large crystals of white feldspar. There are many other types of coarse igneous rock (such as granodiorite from Mountsorrel in Leicestershire), but some are commonly used for construction and should be recognized by most specialists. If molten magma manages to rise through the crust and emerge on the Earth's surface, most famously in the form of volcanic cones or liquid lava flows, it will cool very quickly and form igneous, volcanic rock. Such rapid cooling prevents the development of large crystals, and the resulting rocks are fine-grained with individual minerals difficult to distinguish without a hand lens or microscope. There are examples of such fine volcanic rocks in Great Britain, such as the black basalts of Antrim, Northern Ireland, but few have been commonly used for building in this country. An intermediate magma between these two extremes of origin and crystal shape is injected into the Earth's crust as a molten plate-like body and cooled just below the Earth's surface. They are called sills or embankments. The best example is the Vein Sill from Northumberland, made of the very hard, dark green gray dolerite used extensively in parts of Hadrian's Wall. Although these rocks are widely found, they rarely provide more than local building stone. However, due to their hardness, they are usually mined together. St John the Baptist Church, Muston, Leicestershire, which is made of two contrasting local limestones: the Lowerstone (orange-brown) of the Lower Jurassic Marl Formation and the Middle Jurassic Lincolnshire Limestone (cream-colored). Sedimentary rocks include our most common building stones - sandstone and limestone. Sandstones are formed by the weathering and erosion of pre-existing rocks. They consist of small pieces or grains held together by natural cements such as calcium carbonate (calcite) or silica. Most sandstones are composed of grains.
