合肥盆地中—新生代物源及古水流体系研究
|
摘要
根据地球物理和地质资料, 利用地震地层学和沉积学方法, 对合肥盆地中生代侏罗系、白垩系和新生代的下第三系的物源及古水流进行了研究。合肥盆地中—新生代主要发育大别、张八岭、霍邱和蚌埠等物源及古水流体系。其中, 在侏罗纪以大别物源及古水流体系为主, 在白垩纪张八岭和大别物源及古水流体系为主要的物源及古水流体系,蚌埠物源及古水流体系主要发育在新生代。张八岭和大别物源及古水流体系为主要的物源及古水流体系, 霍邱、蚌埠物源及古水流体系是盆地内部次一级的物源及古水流体系。
Based on the latest geophysical and geological data, this study has dealt with the provenance and paleocurrents in the Mesozoic and the Cenozoic in the Hefei Basin with seismic stratigraphy and sedimentology, four provenance and paleocurrent systems have been recognized The variation of the provenance and paleocurrents indicates the regular characteristics of the Hefei Basin The main properties of provenance and paleocurrents changed with time from Dabie dominated provenance and paleocurrent system in Jurassic to both Dabie dominated provenance and paleocurrents and Zhangbaling dominated provenance and paleocurrents in the Cretaceous The Bengbu provenance and paleocurrent system became the main provenance and paleocurrents in the Cenozoic This study comes to the conclusion that Zhangbaling system is the predominant, Huoqiu and Bengbu systems are the secondary
