| 摘 要： | 经过对栾家河断裂北段表土矿物成分鉴定和化学分析,该研究区的表土来自经受过低温(<150℃)中至弱碱性热液作用的岩石,主要由斜长石、钾长石、白云母、石英、风化成因的高岭石和热液叠加而成的蒙脱石等矿物混合而成.根据表土矿物蚀变特征与已知矿化带顶部表土特征的对比,工作区内高岭石矿物主要为风化成因,而蒙脱石系热液作用而成.从蚀变粘土矿物特征推断,其深部存在热液金矿化.

| Abstract: | Analysis on the mineral composition and chemical data of the topsoil in the northwest sector of the Luanjiahe fault shows that the topsoil in the study area have undergone low-temperature (<150 ℃), neutral to weak alkalic hydrothermal alteration and consist of potash feldspar, plagioclase, mica, quartz, kaolinite of weathered origin and montmorillonite of hydrothermal origin. Comparison of the altered characteristic of the topsoil in the studied area with those of the topsoil covering the known mi-neralized zones and the hydrothermal origin of the montmorillonite indicates the possible gold mineralization in the sector of the fault under study. |
