At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 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 sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Nickeline (a.k.a. niccoline, niccolite) is a nickel arsenide mineral - NiAs.  It has a metallic luster, a metallic pinkish-orange to pale copper color that tarnishes gray, and a gray streak.  Nickeline is fairly heavy for its size, is moderately hard (H=5 to 5.5), and has no cleavage.  It tends to occur with some Ni-Fe-Cu sulfide\u002Farsenide minerals and with some Co-Ag minerals.\n\u003C\u002Fp>\u003Cp>Locality: Cobalt, Ontario, Canada\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of nickeline:\n\u003C\u002Fp>\n\u003Ca rel=\"nofollow\" class=\"external text\" href=\"http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=2901\">www.mindat.org\u002Fgallery.php?min=2901\u003C\u002Fa>","James St. John",2498,1994,{"id":625,"source_url":626,"license_code":430,"credit_html":627,"title":628,"description":629,"author":630,"original_width":631,"original_height":632},6017,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=70553560","David Hospital, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=70553560\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Nickeltsumcorite & Annabergite II.jpg","Nickeltsumcorite is a very rare new mineral species (IMA 2013-117), this is the nickel analogue of tsumcorite and cobalttsumcorite.

They called it a bloom — a soft, earthy coating that spread over weathered ore.\n\nAxel Fredrik Cronstedt put it in print first. In 1758 he mistook the green stuff for a nickel oxide and gave it the Latin name *Ochra niccoli* — nickel ochre[1]. Twenty years later, in 1778, Wallerius renamed it nickel bloom[2].\n\nThe modern name arrived in 1852. Henry James Brooke and William Hallowes Miller described the mineral properly and named it after Annaberg, the silver-mining town in Saxony where some of the first specimens were collected[3].\n\nThe green colour was more than a curiosity to those miners. A bright stain on the rock face told them that nickel and arsenic ores lay nearby, hidden in the unweathered vein below. The mineral was a sign to follow, not a thing to dig out[4].","claude-opus-4-8","1.7.0",{"markdown":771,"model_version":768,"prompt_version":769,"reviewed_at":11},"Annabergite is not an ore and is not mined for industry. It forms only as a thin secondary crust where nickel-arsenic minerals have weathered, so it never gathers in the quantity a metal works would need[1].\n\nWhat demand exists comes from collectors. Well-formed crystals are rare; the mineral usually appears as soft earthy masses and encrustations, and a clean apple-green specimen is prized for its colour[2].\n\nA specimen is also a piece of arsenic chemistry. The mineral is a nickel arsenate, Ni₃(AsO₄)₂·8H₂O, which means the toxic element arsenic is locked into its structure."]
