塔里木盆地寒武系层序地层格架
|
摘要
通过露头、钻测井及地震层序地层特征综合分析,建立了塔里木盆地寒武系三级层序地层格架,将寒武系划分出6个可全盆地追踪与对比的三级层序。结合反映全球海平面相对变化的全岩碳同位素旋回与反映沉积古水深相对变化的沉积旋回的对比分析,可将塔里木盆地寒武系三级层序分为主要受全球海平面变化控制形成的全球海平面层序(层序CSQ2、CSQ4、CSQ5、CSQ6)及主要受地区性构造沉降作用控制形成的构造层序(层序CSQ1、CSQ3)2类。塔北轮南地区寒武系台地边缘总体呈现由早寒武世的缓坡向中—晚寒武世的镶边台地的演变以及由西向东的进积叠置型式,推测主要与寒武纪全球海平面总体微弱下降及塔里木盆地基底沉降速率总体稳定且较小有关。
Synthesizing the sequences characteristics of outcrop,drilling log and seismic data,the 3rd order sequence stratigraphic framework of Cambrian in Tarim basin has been established,and the Cambrian can be divided into six 3rd order sequences tracing and correlating in whole Tarim basin. Contrasting and analyzing between carbon isotope cycles of whole rock reflecting global sea level change or eustatic change and sedimentary cycles reflecting depositional water depth,the 3rd order sequences of Cambrian in Tarim basin may be divided into 2 types as eustatic sequence (sequence CSQ2,CSQ4,CSQ5,CSQ6),of which formation chiefly controlled by eustatic change,and tectonic sequence (sequence CSQ1,CSQ3),of which formation chiefly controlled by regional tectonic subsidence. The Cambrian platform margin in Lunnan area,northern Tarim basin,was generally behaved as evolution from ramp in Early Cambrian to rimmed platform in Middle—Late Cambrian,and progradational stacking style from west to east,it's speculated mainly related to faint eustatic fall in Cambrian and general stable and little tectonic subsidence in Tarim basin.
