Significance and characteristics of paleotectonic migration in Bachu-Makit area of Tarim Basin
摘要
Abstract
The Bachu-Meigeti area in the Tarim Basin experienced multi-period tectonic movement.It is of great significance to reconstruct the tectonic evolution of the area and to guide the exploration of oil and gas,which depicts accurately the shape and migration characteristics of the paleotectonic.Combined with geological and geophysical studies,applying the thickness map method to reflect the palaeotectonic of the upper boundary of the Lower Cambrian in the Bachu-Meigeti area,and discuss its migration process.And the vertical tectonic variation intensity method is used to quantitatively calculate the tectonic activity degree of the study area.The results show that:1) In the west of the study area,there is a large-scale migration of paleotectonic,while the eastern part is relatively stable.2) There is relatively stable of tectonic activity during Caledonian-Early Himalayan period,and strong in Late Himalayan period.A multi-stage relatively inactive zone is developed along the Maketi slope.3) The Lower Cambrian dolomite in the eastern Maketi slope is characterized by relatively low activity intensity,and a higher structural position relative to the hydrocarbon generation depression,which is the favorable objective area for the migration and accumulation of oil and gas.关键词
