在新疆阿克苏前寒武纪蓝片岩相变质的磁铁石英岩夹层中发现了迪尔闪石(Fe2 +12 Fe3 +6Si12 O40 (OH) 10 ) ,其共生的矿物组合为 (ⅰ )迪尔闪石 +钠闪石 +黑硬绿泥石 +黑柱石 +磁铁矿 +石英 ;(ⅱ )迪尔闪石 +黑硬绿泥石 +磁铁矿 +石英 .矿物化学成分分析和共生矿物组合表明阿克苏的迪尔闪石为贫Mn型的迪尔闪石 ,与Alps的迪尔闪石相似 ,但比Alps迪尔闪石更接近纯端元组分 .根据迪尔闪石稳定P T条件 ,阿克苏迪尔闪石的形成条件为压力大于 1 .0GPa ,温度 30 0~ 40 0℃ ,地热梯度在 1 0℃ /km左右 .
Deer amphibole (Fe2 + 12 Fe3 + 6Si12 O40 (OH) 10) was found in the magnetite-quartz intercalations of the Precambrian bluesky schist in Aksu, Xinjiang. The symbiotic mineral assemblages are (i) Dillerstone + sodium Amphibole + black hard chlorite + blackstone + magnetite + quartz; (ii) Deer amphibole + black hard chlorite + magnetite + quartz. The combination of mineral chemical composition analysis and symbiotic mineralization indicates that Aksu Di Stellerite is a Mn-deficient Deer amphibole, similar to Alps’s Deere amphibole but nearer to the pure endmember than Alps Deer amphibole.According to Deer amphibole stable PT conditions, Stone formation conditions for the pressure greater than 1.0GPa, temperature 30 0 ~ 40 0 ℃, geothermal gradient at 10 ℃ / km or so.
