摘　　要：兰坪县河西锶矿区含矿岩性为一套碳酸盐岩,矿体主要受断裂控制。通过半封闭还原法分析SrSO_(4)含量93.37ω%。形成于干旱气候的开阔海相沉积环境。通过硫同位素测定,锶来源于石钟山组内,后经热液改造富集成矿,矿床类型属沉积-热液型矿床。The ore-bearing rocksof the Hexi strontium mining area,Lanping County,is a set of carbonate rocks.The ore body is mainly controlled by faults.The SrSO_(4) content of which is 93.37ω%,analyzed by semi closed reduction method.It was formed in an open marine sedimentary environment with arid climate.The strontium was originated from the Shizhongshan Formation and was enriched and mineralized by hydrothermal fluids.The deposit is a sedimentary-hydrothermal type.
