The yellow to pink mineral occurs as small, needle-shaped crystals. It was first discovered in 1917 from a mine in Iron County, Michigan, United States and identified in 1930. , seamanite is known from four sites in Michigan and South Australia. ==History== In 1917, Arthur E. Seaman collected a mineral sample from the Chicagon Mine in Iron County, Michigan. He correctly believed it to be a new mineral species based on a qualitative analysis of its composition by F. B. Wilson. World War I delayed further study of the mineral until 1929. A study in 1930 proved it to be a new mineral and named it ''seamanite'' in honor of Seaman. They cited his career as a professor of geology and mineralogy and his contributions to the field as reasons for the naming.〔Kraus, p. 220.〕 The original analysis of the mineral in 1930 suggested seamanite to be a hydrated salt.〔Kraus, p. 223–5〕 However, in 1971, the mineral was determined to be the coordination compound Mn3()(PO4)(OH)2.〔Moore, p. 1527.〕 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「Seamanite」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
