摘要
六块地—厢房矿区的硫铁矿矿体,受下元古界辽河群里尔峪组二段:浅粒岩、变粒岩控制,以电气变粒岩为顶底标志。绿帘石化和绿泥石化为矿体是近矿蚀变,范围较小。电气石化范围广,是较好的找矿标志。利用黄铁矿的热电性确定矿体部位和矿化富集趋势。
The pyrite ore body in Liukuaidi-Xiangfang mining area is controlled by leptite and leptynite which belongs to the second stage of Lieryu Fm, Liaohe Group, Lower Proterozic, marked by the top and bottom of tourmaline leptynite. Epidotization and chloritization is close to ore body, the alteration area is small. Wide range of tourmalinization is favourable prospecting criteria. Using the pyroelectricity of pyrite to ensure ore body and mineralization enrichment trend.
