奥地利 紅寶石 黄铁矿 石墨
Corundum (Variety: Ruby) with Graphite and Pyrite
刚玉（红宝石品种）伴石墨和黄铁矿
English Description
Minerals: Corundum (Variety: Ruby) – Al₂O₃, Graphite – C, Pyrite – FeS₂
Locality: Amstall, Mühldorf, Krems-Land District, Lower Austria, Austria
Dimensions: 5.60 cm x 4.95 cm x 3.35 cm
Weight: 95.09 grams
Description: This specimen features well-formed ruby crystals embedded in a matrix of graphite and pyrite. The deep red hue of the ruby contrasts strikingly with the metallic luster of pyrite and the dark sheen of graphite. Such associations are indicative of high-temperature metamorphic environments where aluminum-rich and carbon-rich rocks interact. The presence of pyrite suggests sulfur-bearing fluids were present during formation, contributing to the unique mineral assemblage.
中文介绍
矿物：刚玉（红宝石品种） – Al₂O₃，石墨 – C，黄铁矿 – FeS₂
产地：奥地利下奥地利州克雷姆斯兰县米尔多夫阿姆斯塔尔
尺寸：5.60 厘米 x 4.95 厘米 x 3.35 厘米
重量：95.09 克
描述：此标本展示了嵌入石墨和黄铁矿基质中的形态良好的红宝石晶体。红宝石的深红色与黄铁矿的金属光泽和石墨的暗色光泽形成鲜明对比。这种组合表明在高温变质环境中，富铝岩石与富碳岩石发生了相互作用。黄铁矿的存在表明在形成过程中有含硫流体的参与，促成了这一独特的矿物组合。
