摘要

应用Q型聚类、相关分析和ZTR指数等数理统计方法，对柴达木盆地北缘古近系碎屑岩中的重矿物进行稳定矿物和非稳定矿物及其组合特征进行了分析，并判断其物源方向。古近系的重矿物主要表现为稳定矿物含量大于非稳定矿物的含量，表明该区沉积物搬运距离较长，离物源区相对较远。柴达木盆地北缘古近系各层组的重矿物类型及其组合形式、ZTR指数分布特征等均很接近，表明物源在沉积演化过程中具有明显的继承性。综合分析得出物源方向有3个:北西部阿尔金山物源区、小赛什腾山—赛什腾山物源区和东部的祁连山—绿梁山物源区。三大物源区内可进一步分为若干小的物源区，各物源相对独立，仅在冷湖四号、五号构造带受阿尔金山物源区及小赛什腾山物源区的综合影响。

Abstract

Depended on mathematical statistics of Q type cluster,correlation analysis and ZTR indexes,we discuss the stability and non-stability of heavy minerals and their relevant assemblages in the Paleogene clastic rocks in the northern margin of Qaidam Basin,and ensure the direction of the parent sources.The content of stable minerals is more than that of non-stable one in the Paleogene heavy minerals,suggesting that the mineral had accepted a long-distance transport from the parent source.The similar characteristics of heavy mineral types,relevant assemblages and ZTR indexes occurs in interval setting of Paleogene,indicating that the inheritance sedimentation had happened in the evolutional process.Three input directions of parent sources are gotten as follows:northwestern direction from Altyn,Xiao Saishitengshan and Saishitengshan direction,and east direction from Qilian Mountain and Lüliangshan.Each source can divide into some smaller one and each of small sources is relatively independent.The fourth and fifth tectonic belts of Lenghu were commonly affected by both sources of Altyn and Xiao Saishitengshan.

Key words： Northern margin of Qaidam Basin; Heavy mineral; Source analysis; Paleogene
