摘要
Abstract
Wulasitaiin area is located in east of the southern Kunlun area. It belongs to active orogenic belt with complex metallogenic types. 32 magnetic anomalies have been circled in the region in ground high precision magnet⁃ic survey with the scale of 1∶50000. Among them, 3 abnormalies are class A type, 5 abnormalies are class B type, and 1 abnormaly is class C type. Characteristics of magnetic anomalies in the region have been known primarily. Through anomaly verification work, by using route geological survey, comprehensive geophysical and geochemical profiles and magnetic anomaly inversion for inference and interpretation, it is summarized that the cause of abnor⁃mality is mainly magnetite, low grade magnetite ore chlorite quartz plate and intermediate acid intrusive rocks. The correlation between iron and gold mineralization and magnetic field distribution has been understood. The work fills the gap of regional related information, and provides the basis for other geological work in the area.关键词
