吉林省通化县羊砬子沟花岗岩饰面石材矿床特征及找矿方向

Ore deposit features and prospecting direction of Yanglazigou granite facing stone of Tonghua County, Jilin Province

吉林省通化县羊砬子沟花岗岩饰面石材矿赋存于龙头复式花岗岩体中,矿体石质好、储量大,放射性检测结果远小于国际原子能机构的职业辐射防护安全导则剂量值,因此就γ射线而言是安全的。,是石材开发利用的优质品种。该类型矿体赋存具较强的规律性,同时具有固定层位和区域性,在龙头复式岩体过度相的中粒黑云母花岗岩中开展工作是今后的找矿方向。

The granite facing stone of Yanglazigou ore deposit of Tonghua County, Jilin Province occurrences in Longtou compound granite mass, showing high quality , large reserves, the radioactive detection results is far less than guide for the occupational radiation protection and safety of the international atomic energy agency （iaea） dose value, so in terms of gamma rays is safe , and is the high quality stone material for development and utilization . This ore body occurrences strong regularity, has a ifxed stratohorizon and regionalism. The prospecting in medium-granular biotite granite of the Longtou compound mass of excess phase is direction in the future.
