摘要
1994年,在易门狮子山因民组中下部热水沉积岩中发现(似)层状含铁铜矿体。通过成矿古环境分析及岩石、矿床学研究,认为该矿为中元古代裂谷早期火山一喷流沉积成因,属东川稀矿山式铁铜矿类型,类似于奥林匹克坝型,从而为滇中地区找矿拓宽了思路。
The strata-form Fe-Cu ores were identified in thermal watersedimentary rocks within the Middle-LowerSection of Yidding Formation. Its footwall is constituted by spilite and volcanic sedimentsry breccia. Researching on Petrology,mineralization and metallogenic environment indicate that it is an originally early volcano-spout sedimentary cOPPer dePOSitformed in Middle Proterozoic rift. Similar to the Olympic Dam ore dePOSit, it belongS to XikUangshan-tin Fe-Cu dePOsit.Thus, this signifiCantresearches can broaden our thoughts for the prospetong of ndneralreSOurces in central Yunnan.
