Abstract

Abstract: The latest high-precision aeromagnetic data is used to interpret the regional magnetic characteristics of the East Kunlun-Altyn Tagh area in the light of the different magnetic anomalies, which strik generally in NE and nearly EW, and remarkable for their obvious partitioned and segmented features. With the assistance of the Satellite gravity data and the processes of the analytic continuation and horizontal derivative, the geophysical and geological data revealed the magnetic anomaly of the fault structure, especially the deep fracture. The magnetic anomaly is mainly characterized by the boundary, gradient zone, and beaded anomalies. The faults act not only as the important tectonic boundaries in this region, but also the important tectonic belts, controlling the distribution of mineralization. Based on the magnetic interpretation and practical applications, we described the relation between the deep fracture and mineralization. In the East Kunlun-Altyn Tagh region, many known medium and pint-sized deposits are located nearby the deep fractures.

Key words: high-precision airborne magnetic, fault structure features, East Kunlun, Altyn Tagh south rim fracture
