摘要
南京附近宁镇山系湖山地区.中石炭世与下石炭世之间.由于海水处于高能状态,发生强烈运动冲刷海底,使已沉积的物质受到侵蚀,进行悬浮搬运,当海水平静后,呈悬浮状态的物质又沉积下来,造成水下沉积间断或称水下假整合.
Ningzhenshan near Nanjing belongs to Husan district.During Mid-Late Carboniferous Periods,because the sea water was in high energy status,strong movement occured,which scoured the sea floor,eroded deposited matter,thus,suspension transport was carrying out.When the sea water was calm,the suspended matter deposited again,which caused subfluvious deposional break hiatus or subfluvial deceptive conformity.
