陆架沉积是海洋地质学与第四纪地质学共同研究的对象.我国陆架海底沉积调查已有几十年历史,编制了大量底质类型图件,但却未能编制第四纪地质图.只是在近几年才开始尝试编制海底第四纪地质图.本文主要讨论如何利用底质调查资料编制第四纪地质图,其中主要涉及海洋地质学上的“残留沉积”,“现代沉积”在第四纪地质图上如何处理,陆架表层沉积物成因类型如何划分,沉积物地层时代如何确定等问题. The shelf sedimentation is the object of marine geology and quaternary geology research.China’s shelf seabed sediment survey has been decades of history, compiled a large number of sedimentary types of maps, but failed to compile the Quaternary geological map. In recent years, attempts have been made to develop the seabed Quaternary geology map.This paper mainly discusses how to use the sediment survey data to prepare the Quaternary geological map, which mainly deals with the “residual sediment” in marine geology, How to deal with the Quaternary geology map, how to divide the genesis types of the surface sediments and how to determine the age of sedimentary strata.
