摘要
位于大兴安岭北部的上黑龙江拗陷与黑龙江对岸的俄罗斯布列亚拗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.从拗陷的形成、地质构成、火山活动等因素与成矿的关系诸方面对该拗陷进行了初步的探讨.
The Upper Heilongjiang Depression, located in northern Daxinganling region of China, and the Russian Bureya Depression on the other side of Heilongjiang River, belong to the same Mesozoic fault basin filled with terrigenous detritus and sediments. The resources of oil, gas, coal, gold, silver, copper and some nonmetal minerals are distributed in the depression. With discussion on the formation, structure and volcanic activities, as well as their relationships to metallogenesis, this article carries out a preliminary study about the Upper Heilongjiang Depression.
