Named speiskobalt by Werner (see Hausmann, 1813), but also seemingly equally applied to safflorite and smaltite. Arsenikkobaltkies was used by Karl Johann August Theodor Scheerer for Norwegian skutterudite in 1837 and Arsenikkobalt was used in 1852 by Gustav Rose.","2025-08-11 12:14:23",[],[70,74,81],{"id":71,"name":72,"entrytype":9,"csystem":36,"ima_formula":73,"mindat_formula":73,"hmin":11,"hmax":11,"dmeas":39,"dcalc":39,"primary_image_id":11},30906,"Ferroskutterudite","FeAs\u003Csub>3\u003C\u002Fsub>",{"id":75,"name":76,"entrytype":9,"csystem":36,"ima_formula":77,"mindat_formula":77,"hmin":78,"hmax":44,"dmeas":79,"dcalc":80,"primary_image_id":11},2203,"Kieftite","CoSb\u003Csub>3\u003C\u002Fsub>",5,"7.2","7.63",{"id":82,"name":83,"entrytype":9,"csystem":36,"ima_formula":84,"mindat_formula":85,"hmin":44,"hmax":45,"dmeas":49,"dcalc":86,"primary_image_id":87},2897,"Nickelskutterudite","(Ni,Co,Fe)As\u003Csub>3\u003C\u002Fsub>","NiAs\u003Csub>3\u003C\u002Fsub>","5.97",17654,[89,97,105,115,124,133,142],{"id":90,"name":91,"entrytype":9,"csystem":92,"ima_formula":93,"mindat_formula":93,"hmin":94,"hmax":78,"dmeas":39,"dcalc":95,"primary_image_id":96},1083,"Clinosafflorite","Monoclinic","CoAs\u003Csub>2\u003C\u002Fsub>",4.5,"7.46",5906,{"id":98,"name":99,"entrytype":9,"csystem":100,"ima_formula":101,"mindat_formula":101,"hmin":44,"hmax":44,"dmeas":102,"dcalc":103,"primary_image_id":104},1093,"Cobaltite","Orthorhombic","CoAsS","6.33","6.335",5990,{"id":106,"name":107,"entrytype":9,"csystem":92,"ima_formula":108,"mindat_formula":109,"hmin":110,"hmax":111,"dmeas":112,"dcalc":113,"primary_image_id":114},1407,"Erythrite","Co\u003Csub>3\u003C\u002Fsub>(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>2\u003C\u002Fsub> · 8H\u003Csub>2\u003C\u002Fsub>O","Co\u003Csub>3\u003C\u002Fsub>(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>2\u003C\u002Fsub>·8H\u003Csub>2\u003C\u002Fsub>O",1.5,2.5,"3.06","3.135",8046,{"id":116,"name":117,"entrytype":9,"csystem":92,"ima_formula":118,"mindat_formula":119,"hmin":111,"hmax":120,"dmeas":121,"dcalc":122,"primary_image_id":123},2263,"Köttigite","Zn\u003Csub>3\u003C\u002Fsub>(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>2\u003C\u002Fsub> · 8H\u003Csub>2\u003C\u002Fsub>O","Zn\u003Csub>3\u003C\u002Fsub>(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>2\u003C\u002Fsub>·8H\u003Csub>2\u003C\u002Fsub>O",3,"3.33","3.24",13597,{"id":125,"name":126,"entrytype":9,"csystem":127,"ima_formula":128,"mindat_formula":128,"hmin":129,"hmax":129,"dmeas":130,"dcalc":131,"primary_image_id":132},2265,"Koutekite","Hexagonal","Cu\u003Csub>5\u003C\u002Fsub>As\u003Csub>2\u003C\u002Fsub>",3.5,"8.48","8.437",13608,{"id":134,"name":135,"entrytype":9,"csystem":127,"ima_formula":136,"mindat_formula":137,"hmin":120,"hmax":138,"dmeas":139,"dcalc":140,"primary_image_id":141},2730,"Mixite","Cu\u003Csub>6\u003C\u002Fsub>Bi(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>3\u003C\u002Fsub>(OH)\u003Csub>6\u003C\u002Fsub> · 3H\u003Csub>2\u003C\u002Fsub>O","BiCu\u003Csub>6\u003C\u002Fsub>(AsO\u003Csub>4\u003C\u002Fsub>)\u003Csub>3\u003C\u002Fsub>(OH)\u003Csub>6\u003C\u002Fsub>·3H\u003Csub>2\u003C\u002Fsub>O",4,"3.79","4.04",16386,{"id":143,"name":144,"entrytype":9,"csystem":145,"ima_formula":146,"mindat_formula":146,"hmin":147,"hmax":111,"dmeas":148,"dcalc":149,"primary_image_id":150},684,"Native Bismuth","Trigonal","Bi",2,"9.7","9.753",17098,[],[153],{"id":154,"txt":155,"latitude":156,"longitude":157,"country":158},2497,"Skuterud Mines, Modum West, Modum, Buskerud, Norway",59.9800538,9.8528266,"Norway",534,[161,164,167,171,175,180,185,190,194,198,202,206,210,214,218,222,227,231,235,239,243,247,251,256,260,263,268,272,276,280,284,289,293,297],{"id":162,"year":11,"html":163,"doi":11},16123692,"Wallerius.",{"id":165,"year":11,"html":166,"doi":11},16123693,"Werner.",{"id":168,"year":169,"html":170,"doi":11},16123691,1529,"Georgius Agricola (1529).",{"id":172,"year":173,"html":174,"doi":11},16123694,1813,"Hausmann (1813).",{"id":176,"year":177,"html":178,"doi":179},4455550,1827,"Breithaupt, Aug.

Smaltite is the arsenic deficient variety of Skutterudite, now stripped of its species name. Its habit is so radically different from the \"classical\" style of lumpy crystals on a massive ore, with no contrast. Instead, we have this cityscape arrangement of crystals, reticulated (twinned?!) and complexly intergrown, arranged inside a natural cavity of fluorite and barite matrix. Its long history surely started in the mid to late 1800s and then we can track it from within the collection of noted collector Albert Petereit (1860-1917), who sold it to A.F. Holden (1863-1913) in June of 1910. He donated his substantial mineral collection to the Harvard Mineralogical Museum in 1911. In Harvard it remained until the 1960s when it was traded out to Phil Sclaisi, in whose collection it stayed for some 40 years.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>","Robert M.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5600 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The arsenide minerals contain one or more arsenide anions (As-3).
