摘要
莺歌海盆地泥底辟构造主要是在热动力作用下形成和演化的,包括热传导和热对流作用。热动力作用是主驱动力,沉积物差异重力和水平应力作用是次驱动。莺歌海盆地泥底辟构造实质上是沉积在盆地中、底部的巨厚泥岩层,在经基底传导到上覆沉积层的深部高温场作用下,转变为泥岩高塑性粘流体的热流动、热聚集、热膨胀、热升压、热扩张和热刺穿的物理效应。
The mud diapir structure in Yinggehai Basin,South China Sea,was been formed and evoluted mainly by thermodynamic actions. Compared with the gravitative differentiation and lateral-stress effects,the thermodynamic action is considered as primary driving force,and the others are secondary. The mud diapir structures of Yinggehai region are virtually a physical effect of the thermal flow, aggreation,expansion,rising pressure,and explosing, etc, to transfer mudstone in the basin into mudstone viscous-plastic fluid during the function of deep high temperature field.
