【摘要】 北疆裂谷系包括准噶尔、吐哈、伊犁三大盆地以及它们之间的部分山区.东西总长1200km,南北宽约400km,面积约25×10~4km~2.三个盆地被天山山系分割各在一方.但是航磁异常图却将三个盆地连结在一起,组成一个复杂的“三联式”强磁异常带.从异常特征及沉积建造分析,它很可能是北疆晚古生代裂谷系的反映.更多还原

【Abstract】 Rift system in northern Xinjiang includes Junggar, Turpan - Hami, Ili 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 25×104 km2. These basins are seperated by Tianshan mountains system, but three basins connected by aeromagnetic anomaly map, and formed 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 northern Xinjiang.更多还原
