我国东北地区铀矿床(点)的分布特征与重力场联系的研究结果表明:东北地区几乎所有铀矿床(点)都分布在重力高场的边缘或重力高场向低场的边渡带上。下面举实例说明。 (1)471-470地区:该区位于某构造断裂带南翼,隆起与拗陷的接合部位。区内广泛发育有石炭二迭系火山碱性岩、侏罗系中酸性火山岩和多期花岗岩侵入体。分布有470、471、
The results of the study on the relationship between the distribution characteristics of uranium deposits and the gravitational field in Northeast China show that almost all uranium deposits (spots) in northeast China are distributed along the edge of the high gravity field or the high-low gravity boundary. The following examples illustrate. (1) 471-470 Area: This area is located at the junction of the south wing of a tectonic fault belt and uplift and depression. There are widely developed Carboniferous Permian volcanic alkaline rocks, Jurassic intermediate-acid volcanic rocks and multi-stage granite intrusions. There are 470,471 distributions,
