通过对博湖坳陷侏罗系重矿物组合特征和稳定系数变化特征研究,划分了该地区的沉积区域,并恢复了各沉积分区的母岩性质和岩石类型,从而判断出各沉积分区的物源。认为原始盆地存在两大物源体系及相应的两大古水流体系并处于南北向扩张为主的状态中。
Through the study of the characteristics of the Jurassic heavy minerals assemblage and the variation characteristics of the stability coefficient in the Bohu Depression, the sedimentary area in this area is divided and the parent rock properties and rock types of each sedimentary subarea are restored. source. It is considered that there are two major source systems and two corresponding ancient water flow systems in the original basin and are in a state of dilatancy mainly from north to south.
