皖西北龙山集一带地质构造特征与新构造活动分析
ANALYSIS OF GEO-STRUCTURAL FEATURES AND NEO-TECTONIC ACTIVITY AROUND LONGSHANJI,NORTHWEST OF ANHUI
【摘要】 根据安徽涡阳县龙山集一带地质调查结果与地震活动特征,分析认为龙山集一带呈现北东走向优势构造特征。多个地层剖面显示该地区中更新世以来的沉积地层稳定分布,说明该地区中更新世以来新构造活动不强烈。
【Abstract】 Based on geological investigation results and earthquake activity features around Longshanji,Guoyang County,Anhui Province, it is suggested by analysis that NE-trending structure is dominant in the area around Longshanji.A number of stratigraphic sections show that sedimentary strata have been in stable distribution in the area since mid-Pleistocene,indicating inactivity of neo-tectonics in the area in the same time.
