| 摘 要： | 地面高精度磁测是可以间接找金矿的.它能够可靠地反映控矿地质体的磁性变化,了解隐伏的控矿岩体、构造和含矿蚀变破碎带的分布.利用地面高精度磁测在甘肃某金矿区进行扫面测量,根据磁异常化极平面图圈定了5个花岗岩和灰岩的岩性接触带,从而了解了控矿岩体的分布范围;同时对磁异常进行化极、延拓和求不同方向的水平一阶导数,依据断裂带的磁...

| Abstract: | The method of high accuracy magnetic prospecting on earth surface can help to find gold deposit indirectly.It can indicate the magnetic change of geological body which controls the gold mine,the distribution of rock bodies,structures and alteration crush belt.Using the method of high accuracy magnetic prospecting on earth surface to measure all the gold zone in Gansu,it can delimitate five magnetic rocks' boundary and understand the gold mine and the distribution of rock bodies from the abnormality of accur... |
