HOLOCENE SEA LEVEL CHANGES AND CRUSTAL MOVEMENTS ALONG THE NORTHERN COASTS OF THE SOUTH CHINA SEA

This paper discusses level changes of the sea in the last 6000 years and the recent crustal movements of the coasts of the South China Sea. There was one transgression in the middle Holocene (about 6000-3000 years ago); the sea level might not be higher than the actual one. Many terraces and coral reef platforms above the sea level can be explained by recent crustal movements.As far as the intensity of the crustal movements are concerned, the NE faults are the strongest, the NW next, and the WE are the weakest. They intersect ia block-faulting, differing in seismic activity, crustal movement rate and amplitude. On the whole, they gradually become stronger from west to east in accordance with the increasing tendency of stress field.The land is tilting toward the sea, especially ia western Guangxi Province.     

南海北部沿岸全新世海面变动与近代地壳运动

本文拟探讨南海北部沿岸最近6,000年来的海面变动与近代地壳运动.众所周知,全新世的海面变动,其中包括近6,000年来是否有高海面问题,曾引起广泛的争论.总的说来,大致有R.W.费尔布里奇和F.P.谢帕德两种有代表性的观点.前者认为大西洋期的海面比今天海面高出3-6米,并从那时起,海面具有多次的波动[1];后者认为全新世既没有高海面,也非波动的[2].
