MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky. -

SUMMARY The Department of Commerce (Commerce) preliminarily determines that certain quartz surface products (QSP) from the People’s Republic of China (China) are being, or are likely to be, sold in the United States at less than fair value (LTFV), as provided in section 733 of the Tariff Act of 1930, as amended (the Act). The period of investigation (POI) is October 1, 2017, through March 31, 2018. The estimated margins of sales at LTFV are shown in the accompanying Federal Register notice. II. BACKGROUND On April 17, 2018, Commerce received antidumping duty (AD) and countervailing duty (CVD) petitions concerning imports of QSP from China, filed in proper form on behalf of Cambria Company LLC (the petitioner).1 Commerce published the initiation of this investigation on May 16, 2018.2 In the Initiation Notice, Commerce notified the public that we would select the companies required to respond to our AD questionnaire using data collected via “quantity-and-value” 1 See Petitioner’s Letter, “Petitions for the Imposition of Antidumping and Countervailing Duties: Certain Quartz Surface Products from the People’s Republic of China,” dated April 17, 2018 (the Petition). -
Bedrock Geology Glossary from the Roadside Geology of Minnesota, Richard W
Minnesota Bedrock Geology Glossary From the Roadside Geology of Minnesota, Richard W. Ojakangas Sedimentary Rock Types in Minnesota Rocks that formed from the consolidation of loose sediment Conglomerate: A coarse-grained sedimentary rock composed of pebbles, cobbles, or boul- ders set in a fine-grained matrix of silt and sand. Dolostone: A sedimentary rock composed of the mineral dolomite, a calcium magnesium car- bonate. Graywacke: A sedimentary rock made primarily of mud and sand, often deposited by turbidi- ty currents. Iron-formation: A thinly bedded sedimentary rock containing more than 15 percent iron. Limestone: A sedimentary rock composed of calcium carbonate. Mudstone: A sedimentary rock composed of mud. Sandstone: A sedimentary rock made primarily of sand. Shale: A deposit of clay, silt, or mud solidified into more or less a solid rock. Siltstone: A sedimentary rock made primarily of sand. Igneous and Volcanic Rock Types in Minnesota Rocks that solidified from cooling of molten magma Basalt: A black or dark grey volcanic rock that consists mainly of microscopic crystals of pla- gioclase feldspar, pyroxene, and perhaps olivine. Diorite: A plutonic igneous rock intermediate in composition between granite and gabbro. Gabbro: A dark igneous rock consisting mainly of plagioclase and pyroxene in crystals large enough to see with a simple magnifier. Gabbro has the same composition as basalt but contains much larger mineral grains because it cooled at depth over a longer period of time. Granite: An igneous rock composed mostly of orthoclase feldspar and quartz in grains large enough to see without using a magnifier. Most granites also contain mica and amphibole Rhyolite: A felsic (light-colored) volcanic rock, the extrusive equivalent of granite. -

Wollastonite–A Versatile Industrial Mineral
Industrial Minerals of the United States Wollastonite–A Versatile Industrial Mineral What is Wollastonite? Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Wollaston (1766–1828). It is composed of calcium (Ca) and silicon and oxygen (SiO2, silica) with the chemical formula CaSiO3. Although much wollastonite is relatively pure CaSiO3, it can contain some iron, magnesium, (Above and right) Hand specimens of manganese, aluminum, potassium, wollastonite showing acicular crystal clusters. sodium, or strontium substituting for calcium in the mineral structure.

Researching Stonehenge: Theories Past and Present
Parker Pearson, M 2013 Researching Stonehenge: Theories Past and Present. Archaeology International, No. 16 (2012-2013): 72-83, DOI: http://dx.doi.org/10.5334/ai.1601 ARTICLE Researching Stonehenge: Theories Past and Present Mike Parker Pearson* Over the years archaeologists connected with the Institute of Archaeology and UCL have made substantial contributions to the study of Stonehenge, the most enigmatic of all the prehistoric stone circles in Britain. Two of the early researchers were Petrie and Childe. More recently, colleagues in UCL’s Anthropology department – Barbara Bender and Chris Tilley – have also studied and written about the monument in its landscape. Mike Parker Pearson, who joined the Institute in 2012, has been leading a 10-year-long research programme on Stonehenge and, in this paper, he outlines the history and cur- rent state of research. Petrie and Childe on Stonehenge William Flinders Petrie (Fig. 1) worked on Stonehenge between 1874 and 1880, publishing the first accurate plan of the famous stones as a young man yet to start his career in Egypt. His numbering system of the monument’s many sarsens and blue- stones is still used to this day, and his slim book, Stonehenge: Plans, Descriptions, and Theories, sets out theories and observations that were innovative and insightful. Denied the opportunity of excavating Stonehenge, Petrie had relatively little to go on in terms of excavated evidence – the previous dig- gings had yielded few prehistoric finds other than antler picks – but he suggested that four theories could be considered indi- vidually or in combination for explaining Stonehenge’s purpose: sepulchral, religious, astronomical and monumental. -

Choosing stone need not be the same experience. By understanding stone’s basic properties you can make an educated decision when you are selecting stone for your next project. The ‘right stone’ for your project needs to meet requirements based on appearance and performance. Selecting suitable flooring, for example, is firstly a matter of personal taste. One of the appealing aspects of using stone is how its unique character can be used to display your own distinctive personality. The range of colours, textures and finishes available in stone now rivals the range available in more ‘traditional’ floor coverings. Like these coverings, choosing a stone that is durable and resistant to staining and wear is important. The first step is to understand the strengths and challenges of the various types of stone available. Below is a brief beginner’s guide to the seven main stone types commercially available. Stone Type: Sandstone Formation and composition: A sedimentary rock composed predominantly of quartz usually cemented together with clay and/or fused with secondary silica which has been chemically deposited. Minor minerals containing iron and manganese (among others) give the stone its unique characteristics. The movement of these soluble minerals throughout the stone can produce banding or develop as a uniform colour. -
