標 本 名: | 電気石 (Tourmaline), Variety: ショール (鉄電気石) (Schorl)
| 化学組成: | NaFe3+2Al6(BO3)3[Si6O18](OH)3(OH) | サ イ ズ : | 17,9 x 8,4 x 7,9 & 15,4 x 7,4 x 7,2 mm | 重量: | | 透明: | | 数量 : | | 産地: | Palelni mine, Khetchel (Khat Che) village, Molo quarter, Momeik Township, ビルマ(ミャンマー) Burma (Myanmar) | These 電気石 (Tourmaline) 結晶 crystals show depp brownish red coloration beside partly opaque sections. I rather declare them as ショール (鉄電気石) (Schorl) 結晶 crystals and not as 苦土電気石 (Dravite) due to the more typical growth structure, same as ショール (鉄電気石) (Schorl) 結晶 crystals from this mine as well as the fact that not the whole 結晶 crystals reveals this coloration.
