河南秦岭东部韧性剪切带对金矿成矿及分布的影响

INFLUENCE OF THE DUCTILE SHEAR ZONE TO THE GOLD MINERALIZATION AND DISTRIBUTION IN EASTERN QINLING MOUNTAINS, HENAN PROVINCE

摘要: 通过对研究区的地质背景、韧性剪切带的特征、金矿的产出特征等方面研究，发现本区绝大部分金矿体赋存于脆-韧性和脆性剪切带中.剪切带不仅是金运移的通道和储存场所，而且与金的活化、迁移有着密切的联系.剪切带控制着石英脉或蚀变带的分布，从而控制着该区金矿床（点）的分布.

Abstract: Study on the geological background, ductile shear zone, occurrences of gold deposits shows that most of the gold ore bodies in the area occur in the brittle-ductile and brittle shear zones. The shear zones are not only the migration channels and storage spaces for gold, but also closely related to gold activation and migration. At the same time, the shear zones control the distribution of quartz veins and altered belts, thus the distribution of gold deposits (spots) in the area.
