Diadochite is a phospho-sulfate mineral. It is a secondary mineral formed by the weathering and hydration of other minerals. Its formula is Fe2(PO4)(SO4)OH·5H2O. Well crystallized forms are referred to as ''destinezite'', which has been given official recognition by the International Mineralogical Association with diadochite being the poorly formed to amorphous variety.〔http://www.mindat.org/min-1279.html Mindat diadochite〕〔http://www.mindat.org/min-5222.html Mindat destinezite〕 It has a greenish yellow to brown colour and forms nodules or crusts. Its appearance has been compared to cauliflower. Identified originally in Belgium in 1831, it has been found in many places throughout the world. It occurs as a secondary mineral in mineral gossans, coal deposits, phosphate rich pegmatites and cave guano deposits.〔http://rruff.geo.arizona.edu/doclib/hom/diadochite.pdf Handbook of Mineralogy〕 ==References== 〔 *(Webmineral ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diadochite」の詳細全文を読む スポンサード リンク
