【摘要】 <正> 逆掩断层是地壳构造运动的一种表现形式,在地质构造中广泛发育。在动力学机制上主要反映两种型式,即朱夏教授总结的板内变形七种机制中的两种:A式俯冲(A—Subduction)和基底滑移(Basement ramp)(朱夏,1982)。这两种机制造成的构造运动,不仅影响着含油、气盆地的形成、发展,而且也在一定程度上对盆内和盆缘的油气运移、聚集起着控制作用。更多还原

【Abstract】 This article makes an approach to the control of thrusting over migration and accumulation of oil and gas in light of the characteristics of the thrusts during their development. It is believed, through theoretical derivation and comparing the results of simulation experiments with the objective reality, that it is most possible for oil and gas to accumulate in places where the thrust surface becomes steeper. It is suggested that geologists should pay more attention to this belt in search of oil and gas deposits.This article focuses discussion on the control of thrusting over migration and accumulation of oil and gas, rather than the process of their migration or accumulation.It is hoped that this paper could provide useful informations for the search of additional oil and gas resources in thrust belts and for further advancing the works on new domains and new areas.更多还原
