通过地震资料解释分析得出乌尔逊凹陷断裂在平面上可划分为4个带,呈近SN向、NEE向与NE向3个方向展布。在垂向上根据区域不整合面把断层分为断陷断层系统、断坳断层系统和长期继承性断层。乌尔逊凹陷断层形成与演化主要受铜钵庙组末期拉张作用,伊敏组末期张扭作用和青元岗末期反转作用控制。
通過地震資料解釋分析得齣烏爾遜凹陷斷裂在平麵上可劃分為4箇帶,呈近SN嚮、NEE嚮與NE嚮3箇方嚮展佈。在垂嚮上根據區域不整閤麵把斷層分為斷陷斷層繫統、斷坳斷層繫統和長期繼承性斷層。烏爾遜凹陷斷層形成與縯化主要受銅缽廟組末期拉張作用,伊敏組末期張扭作用和青元崗末期反轉作用控製。

The faults of Wuerxun depression is divided into four zones on plane through the analysis of seismic data interpretation,distributed at nearly SN,NEE and NE three directions.And on vertical the fault is divided into fault depression fault system,fault sag fault system and long-term inherited fault by regional unconformity.The formation and evolution of Wuerxun depression＇s fault is mainly controlled by tensional function at the end of Tongbomiao deformation,tensional and torsional function at the end of Yimin deformation and reverse function at the end of Qingyuangang deformation.
