准噶尔盆地马桥凸起区J_1s沉积物源分析

Analysis of J_1s Sedimentary Source in Maqiao Salient Area in Junear Basin

马桥凸起是准噶尔盆地中央坳陷区内的一个二级构造单元。具良好的油气前景,是新发现的重要油气勘探区域。通过对该区重矿物分析、岩石组分等的分析,首次发现该区沉积物源来自两个方向,一个是北东方向的莫北地区,另一个是西北的小拐方向。

Maqiao salience is a secondary tectonic unit in the central depression area of Jungar Basin, which is a newly found important oil and gas exploration area with good prospects of oil and gas. Through analyses of heavy minerals and rock compositions, it is first found that the sedimentary source in the area comes from 2 directions, one is Mobai area in east-north direction, the other is Xiaoguai direction.
