Crocoite on goethite West Comet Mine. This mine was one of the bigger operation in the district and produced crocoite. There are a few specimen found and generally had botryoidal gossan and this specimen is typical.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eGoethite\u003c\/strong\u003e is a mineral belonging to the diaspore group, characterized as iron(III) oxide-hydroxide, specifically in its α-polymorph form. It is commonly found in soil and low-temperature environments, including sedimentary contexts. Historically recognized for its use as a pigment, particularly brown ochre, goethite has been identified in ancient paint samples from the Lascaux caves in France. The mineral was first documented in 1806, based on specimens from the Hollertszug Mine in Herdorf, Germany, and is named in honor of the German polymath Johann Wolfgang von Goethe.\u003c\/p\u003e \u003cp\u003eGoethite is composed of iron oxyhydroxide with ferric iron as its primary element. It serves as a significant component of rust and bog iron ore. The mineral exhibits a hardness of 5.0 to 5.5 on the Mohs Scale and has a specific gravity ranging from 3.3 to 4.3. While it typically forms massive structures, goethite can also appear as prismatic needle-like crystals, often referred to as \"needle ironstone.\"\u003cbr\u003e\u003c\/p\u003e","brand":"Crystals2Collect A.C.N 651.525.727 Pty Ltd","offers":[{"title":"125 100 50 300","offer_id":52539623670036,"sku":"125 100 50 300","price":685.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/2047\/9764\/files\/Screenshot_20260514_211726_Facebook.jpg?v=1779211453","url":"https:\/\/crystals2collect.com\/products\/crocoite-with-goethite-west-comet-mine-dundas-tasmania","provider":"Crystals2Collect ","version":"1.0","type":"link"}
