| 摘 要： | 岩性圈闭作为三湖坳陷下一步勘探的主要对象,明确物源区及各源区对坳陷内部的影响范围是首要任务。依照重矿物"相关性分析定母岩类型、因子分析定物源主次、Q聚类分析定影响范围、稳定系数分析定物源方向"的研究思路,综合分析研究区内所有重矿物数据的数理统计特征,发现工区母岩类型主要为变质岩、中基性喷出岩和少量沉积岩,分别对应南部昆仑山主要物源、东北埃姆尼克山次要物源和北部祁连山弱物源。南部物源主要控制南斜坡区沉积,但其中西南昆仑山—那北分支物源影响范围可达北斜坡台南—涩北气田一带;东北物源对坳陷内部影响范围局限在盐湖、哑叭尔及察尔汗一带;北部物源对区内沉积起微弱作用。 |

| Abstract: | Since lithologic trap is the mainly continuing exploration object of Sanhu Depression,confirming the provenance and the respective influence area on the inside of the depression is the current priority task.Research thought of the provenance analysis of heavy minerals is as follows: correlation analysis determines source rock types;factor analysis determines provenance levels;Q type cluster analysis determines influence area;stability coefficient determines transportation direction.According to that thought... |
