钻孔及探槽探测鉴定横岗-罗湖断裂活动性
|
摘要
在收集前人有关深圳市横岗-罗湖断裂研究成果的基础上,对该断裂地表出露段开展野外地震地质调查,在断裂沿线隐伏地段布置横跨断层的钻孔探测剖面、探槽,通过对断层几何结构特征分析及碳-14(14C)、光释光(OSL)、电子自旋共振(ESR)样品年代测试、岩石薄片鉴定等手段,确定了断裂对上覆第四纪地层的影响,并鉴定出断裂最新的活动年代。
Based on the previous research achievements of Henggang-Luohu fault in the city of Shenzhen,through the field seismic geology survey on the surface outcrop section of the fault,drilling、trenching exploration crossing insidious section,analysis of the fault's geometric structure,combined with the soil sample age test by C14、TL、OSL and rock slice identification,the fault's influence on quaternary strata is identified,and the latest activity time is appraised in the paper.
