1) gold bearing siliceous ultramylonite
含金硅质超糜棱岩
2) goldbearing mylonite belt
含金糜棱岩带
1.
By high precision magnetic measurement,the basement structures and fault structural framework are analysed,and then two groups of goldbearing mylonite belts :NE-and EWtrending, are outlined,where on the joint position are Daban gold deposits.
应用高精度磁测结果对大板金矿区的基底构造、断裂构造格架进行分析,追索和圈定含金糜棱岩带,结果表明,从构造格架上看大板金矿与排山楼金矿既有可比性,又具其独特性;高磁推断的近东西向糜棱岩带为本区金成矿有利地段。

补充资料:糜棱岩
糜棱岩 mylonite 原岩遭受强烈挤压破碎后形成的一种动力变质岩。主要由细粒石英、长石及少量新生绢云母、绿泥石等矿物组成。矿物颗粒细小,一般小于 0.5毫米。具明显的条带状和眼球状构造,线理发育。显微镜下可见碎屑矿物具波状消光、解理和双晶纹弯曲 、颗粒边部碎裂等现象 。岩性致密、坚硬。主要由花岗岩、石英砂岩等刚性岩石经强烈动力变质形成。多发育于扭性或压扭性断裂带。依糜棱岩化程度分为糜棱岩化岩、糜棱岩、超糜棱岩和千糜岩等。 |
