【摘要】 碗窑沟断裂展布于博格达北凸弧形构造山脉西翼西北麓山前(东山地区)的梁状黄土台地上,介于乌鲁木齐河与水磨河之间。断裂向西北延伸从乌鲁木齐市区穿过,被市区乌鲁木齐河谷厚约40 m的第四系黄土、砾石层覆盖。该断裂系乌鲁木齐市主要的晚更新世中期活动断层。采用高精度浅层地震探测手段,结合钻孔勘探,探测出乌鲁木齐红光山南侧的碗窑沟断层隐伏段的精确位置及运动特征。更多还原

【Abstract】 Wanyaogou fault located at western earth dam of northern Bogeda arc structure beside mountain which was between Urumuqi river and Shuimo river. This fault crossed city with northwest direction and was covered with quaternary loess from Urumuqi valley and the thickness was about40 m. The fault belongs to middle stage of late Pleistocene active fault in Urumuqi. By using shallow artificial seismic and geophysical methods,this paper distinguished characteristics and accurate location of Wanyaogou fault which lied southern side of Hongguangshan.更多还原
