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. -
Tiger's Eye Is Not a Pseudomorph Glenn Morita in the Early 1800’S, Mineralogists Recognized That Tiger’S Eye Was a Fibrous Variey of Quartz
Minutes of the 05/20/03 Westside Board Meeting VP Stu Earnst opened the meeting at 7:31pm. Treasurer’s report read by Kathy Earnst. Minutes approved as published in the newsletter. Old business: Lease on Walker valley discussed. The expiration notice was sent but we are not sure who it went to. We do not see any obstacle to renewal as communication between the council and DNR are open and ongoing. Special thanks, to DNR representative, Laurie Bergvall and DNR staff for their time and effort in hearing our concerns and working towards mutually beneficial solutions on the Walker Valley issues. Sign production is on hold until the sign committee decides where and what the signs will say. We have decided that they will not be on the gate but separate from it. There will be a gate going up at Walker Valley but we will have access to that lock and it will probably be a combo type of thing that we can easily give to other rockhound clubs going there. Talked about the possibility of posing the combo on website but that will depend on the type of gate they put up and what ends up being possible with the mechanics of that gate. New business: Thank you from Bob Pattie and Ed Lehman to Bruce Himko and AAA Printing for donation of the paper. Thank you to Danny Vandenberg for providing sample Walker Valley Material to DNR to show the value of the material we are trying to preserve and enjoy. Bob Pattie is pursuing with the retrieval of our state seized funds through the unclaimed property process. -

The New IMA List of Gem Materials – a Work in Progress – Updated: July 2018
The New IMA List of Gem Materials – A Work in Progress – Updated: July 2018 In the following pages of this document a comprehensive list of gem materials is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on Gem Materials of the International Mineralogical Association. The list will be updated on a regular basis. Mineral names and formulae are from the IMA List of Minerals: http://nrmima.nrm.se//IMA_Master_List_%282016-07%29.pdf. Where there is a discrepancy the IMA List of Minerals will take precedence. Explanation of column headings: IMA status: A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). Gem material name: minerals are normal text; non-minerals are bold; rocks are all caps; organics and glasses are italicized. Caveat (IMPORTANT): inevitably there will be mistakes in a list of this type. We will be grateful to all those who will point out errors of any kind, including typos. Please email your corrections to [email protected]. Acknowledgments: The following persons, listed in alphabetic order, gave their contribution to the building and the update of the IMA List of Minerals: Vladimir Bermanec, Emmanuel Fritsch, Lee A. -

Common Fossils, Rocks and Minerals in Scotland
Geology ish .c ott o Sc m C Common Fossils, Rocks and o d lle n cti la ng in Scot Minerals in Scotland Scotland is extremely lucky as it has many different types of fossils, minerals and rocks. It is possible to find and collect rock, fossil and mineral specimens provided it is done in a responsible manner and the Geological Fieldwork Code is followed. In time the Scottish Fossil Code will provide detailed information on the collection and care of fossils in Scotland (both codes can be found on www.ScottishGeology.com). The following pages list some of the more commonly found geological specimens. In museums and books, we often see only the best examples. Here, we have chosen not to photograph such specimens, but instead have chosen examples which are more likely to be found. The pictures here have a pencil for scale. Words in bold type will be explained, and you’ll find a geological timescale at the end to explain words shown in blue. The Fieldwork Code - the most important bits... Remember the Country Code and observe local bylaws - shut gates and leave no litter Look for loose material to collect first, to avoid hammering at all Don't hammer indiscriminately and remember you don't always need to take a sample Keep collecting to a minimum; leave material left for other people to enjoy If you find anything interesting, tell the local museum. Always make a note/take a photo of where you found it Try to leave sites as you find them Always wear protective goggles when hammering and be aware of where other people are around you Make sure you don't get cut off by the tides 1 Fossils - Animals with Backbones Animals with backbones, for example fish, dogs, and humans are grouped together and called vertebrates. -
