漠河煤盆地形成演化与找矿方向

Mohe Coal Basin Evolution and Exploration Direction

位于大兴安岭北部的上黑龙江坳陷与黑龙江对岸的俄罗斯布列亚坳陷同属一个由陆源碎屑物填充和沉积而成的中生代构造性断陷盆地。其间赋存有石油、天然气、煤、金、银、铜及一些非金属矿产。探讨其发展演化过程,对于在该地区寻找上述矿产将多有裨益。本文从坳陷的形成、地质构成、火山活动等因素与成矿的关系诸方面进行了初步的探讨。

Heilongjiang depression at great Xing＇ an Mountains in the northern part of Heilongjiang, and on the other side of the Russian depression belongs to the same land - based sources filled with debris and deposit from the Mesozoic sedimentary structure rift basin. In which abounds in petroleum, natural gas, coal, gold, silver, copper and some non- metallic minerals. Exploring the development and evolution process in the region will be favourable for looking for the mineral. This paper approaches on the relation between the formation of depression, geological structure, volcanic activity factors est. and minerals formation.
