断陷湖盆陆相层序过程——响应机制的单因素计算机模拟

综合考虑陆源碎屑物供给、内源碳酸盐岩没积、沉积物侵蚀与再沉积、重力流沉积以及构造升降和水平位移等诸多地质因素，建立了一个能够模拟各型盆地的综合数学物理方程式。采用自行研制的定量层序地层模拟系统，以断陷湖盆坡带（泌阳断陷双河～赵凹地区为例），分别模拟了：①湖平面变化过程及其陆相层序响应机制；②基底构造沉降过程及其陆相层序响应机制；③物源供给过程及其陆相层序响应机制。

SINGLE FACTOR COMPUTER SIMULATION ON PROCEDURE RESPONSED MECHANICS OF TERRIGENOUS SEQUENCE IN FAULT DEPRESSED LACUSTRINE BASIN

Synthetically considering plenty of geological factors such as recharge of land source fragmental material,sedimentation of chemically formed canbonatite,sediment erosion and resedimentation,gravity flow,structural adjustment,horizontal displacement and so on,a math physical equation which is comprehensive to simulate every type of basin was set up.Using the simulation system of quantitative sequence stratigraphy designed by the writer of this paper,and taking the steep slope zone of fault depressed lacustrine basin(e.g. Shuanghe Zhaoao area of Biyang fault depression) as a example,the resposed mechanism of terrigenous sequence with the procedure of lacustine level change,and with the procedure of basement structural subsidence,and with the procedure of sedimentary source recharge,has respectively been simulated.
