摘要
根据珊瑚礁类型,南海曾母暗沙实际上是一水深21m的点礁。点礁作NNW—SSE展布,长2385m,宽1380m,其围区(邻近)陆架为碳酸盐陆架。曾母暗沙地处南挤北张的聚敛型的南海南部陆缘。全新世礁的成长率(造礁率)为4.5—8m/yr,造礁珊瑚有34种。笔者认为南海古点礁具有很好的含油气远景。
According to coral reef types, the Zengmu Ridge in the south China Sea is in fact a patch reef at the depth of 21 m. Patch reef strikies NNW-SSE in direction, 2385 m in length and 1380 m in width. Its adjacent shelf is a carbonate shelf.Zengmu Ridge lies on the convergent margin of the southern part of South China Sea,which is compressional on the south and tensional on the north.
The growth rate of the Holocene reef is 4.5-8 m/1000yr. The reef building corals are of 34 species.
The Author believes that the old patch reef in the South China Sea has great oil and gas potential.
