概述在南沙群岛海域开展海上汞量地球化学调查与异常分析的主要成果。从1989至1994年的5个航次中，完成了11655km测线和1790个站的表层海水和海面大气中汞量现场测定。在圈定的19个汞量异常中，推断有9个与下伏油气储层有关，另有7个为断裂带的反映，还有3个可能指示海底存在天然气水合物或深水油气藏。调查结果表明，汞量测量是一种有效的海上油气资源和地质调查手段，能为南沙油气资源远景评价和大型断裂构造调查提供重要的地球化学依据。
Summarize the main achievements of the marine mercury amount geochemical survey and anomaly analysis in the waters of the Nansha Islands. From 5 voyages between 1989 and 1994, on-site measurements of mercury in the surface seawater and sea surface at 11,655 km were completed and 1790 stations were completed. Of the 19 anomalies identified, nine were inferred to be related to underlying hydrocarbon reservoirs and seven to fault zones, and three to indicate the presence of gas hydrate or deepwater reservoirs on the seabed. The survey results show that mercury measurement is an effective means of offshore oil and gas resources and geological survey, which can provide important geochemical basis for the prospect evaluation and large-scale fault structure investigation of Nansha oil and gas resources.
