ON AEROMAGNETIC ANOMALY AND RIFT SYSTEM IN NORTHERN XINJIANG

Abstract

Abstract: Rift system in northem Xinjiang includes Junggar, Turpan-Hami, li basins and some mountainous area among them, with length of 1 200 km in EW direction, width of 400 km in NS direction, the area of 25x 10⁴km² . These basins are seperated by Tianshan mountains system, but three basins connected by aeromagnetic anomaly map, and fommed a complex“trifurcate” strong magnetic anomaly belt. According to analyses of anomaly characteristics and sedimentary formation, it might be a reflection of Late Paleozoic rift system in northem Xinjiang.

Key words: Aeromagnetic anomaly, Junggar basin, Turpan basin, Hamni basin, Ili basin, Rift belt
