辽南上达子堡金矿化区黄铁矿标型特征及意义

The typomorphic characteristics and signifi cance of pyrite in Shangdazibao gold mineralization zone, Southern Liaodong Peninsula

上达子堡金矿化区主要出露古元古界辽河群盖县岩组二岩段,是金成矿物质的矿源层。黄铁矿标型特征指示目前区内的剥蚀水平相当于中上部,按黄铁矿垂直分带规律,{210}+{100}、{210}习性晶体向深部有可能逐渐增加,因此,本金矿化区深部含金量可能高于浅部。

Shangdazibao gold mineralization area mainly outcropped in Gaixian Petrofabric rock section of Palaeoproterozoic Liaohe Group, which is gold mineralization source layer. Typomorphic characteristics of pyrite indicated that the currently denudation extent area was equivalent to the upper part, by pyrite vertical zoning law, {210} ＋ {100}, {210} habit crystals may gradually increase with the depth. Therefore, deep gold content may higher than the shallow in this mineralization area.
