摘要

1.Objectives The research and prospecting degree of these Mesozoic residual faulted basins located in Tonghua and its peripheral areas, such as Tonghua basin, Liuhe basin and Hongmiaozi basin is low.And these basins are considered to be unified sedimentary basins during the Mesozoic (Fig.1).For example, Zhang FQ et al.(2012) believe that the Liuhe basin,Tonghua basin and Yangzishao basin belong to "Great Liuhe basin " which developed under the Xilonggang nappe.According to the research of Xu HL et al.(2013), the Tonghua basin and Liuhe basin began to connect and then formed a unified sedimentary area during the sedimentary period of Linzitou Formation (equivalent to the Xiahuapidianzi Formation);then the basin was uplifted and structural damaged, and finally became a residual basin today.Based on the recent studies, this paper considers that the Tonghua, Liuhe and Hongmiaozi basins are independent faulted basins during the Mesozoic sedimentary period, and there is no unified sedimentary basin.
