安徽省境内宿松群与大别群接触关系性质的厘定

摘 要　 运用构造地层学的理论和方法‚详细解剖了安徽省境内宿松群与大别群在几个重要地段（猪婆寨、梓树坞、杨岩、大新屋和柳坪）接触关系的性质‚提出宿松群南西部的大别群主要是变形变质侵入体‚与宿松群为先侵入、后构造的接触关系。在宿松群大新屋组厚层白云质大理岩之上发现多层透镜状层间砂砾岩层‚沉积和构造标志均显示其层位在大新屋组之上（新建为梓树坞组）‚对原来认为的不整合接触关系和底砾岩提出质疑。

STUDY ON CONTACT RELATIONSHIP BETWEEN THE SUSONG GROUP AND THE DABIE GROUP, ANHUI PROVINCE

The results of detailed mapping in several important sites(such as Zhupozhai, Zishuwu, Yangyan, Daxinwu, and Liuping etc.) along the southern boundry of the Susong Group show that the Dabie Group is composed of deformed and metamorphic intrusive rocks and the ‘bottom conglomerate in the Susong Group’ is a kind of tectonic breccias. The authors think that the contact relationship between the Susong Lithgroup and the Dabie Complex is first intruding, and then being strong deformed.
