Analysis on distribution features of gas outburst from two walls of normal fault and geological origin 正斷層兩盤的瓦斯突出分布特征及其地質成因淺析
The fault faults from basemet to quaternary system , and has the feature of contemporaneous and normal fault 該斷裂自基底一直斷到第四系,具同生正斷特征。
The focal mechanism is mainly left - lateral strike - slip , with a very small normal fault slip component 這次地震的震源機制基本上是左旋走滑,帶有微小的正斷層滑動分量。
The extensional and transtentional structure existed in huabei belongs to vent fault , fracture is mainly stepwise normal fault , whose preservation condition is not good 華北地區(qū)多為張性,張扭性構造,屬于排氣斷層,形成的斷裂多為階梯狀,以正斷層為主,保存條件欠佳。
Several normal faults within the hainan fault zone constitute a fault - step zone and form a narrow and steep zone , which controlled the development and distribution of depositional systems in this area 研究認為,海南斷裂帶的幾個北掉斷層構成斷階帶,形成湖盆邊緣陡且窄的地貌特點,控制了該區(qū)沉積體系的展布規(guī)律。
