【摘要】 在礼乐滩海区用高灵敏度JM-3型金膜测汞仪进行海面大气及表层海水汞量测量,获得三个清晰的大气及海水汞综合异常,礼乐滩海区现有的唯一见到工业天然气的钻井位于Ⅰ号异常区内,而Ⅱ号异常比Ⅰ号异常的强度更高、范围更大。这两个异常可能与沉积盆地内的油气资源有关。Ⅲ号异常被推测为陆壳与洋壳交界处深大断裂带的反映.此次海上汞量测量初步肯定了走航式汞量测量的有效性,它有可能成为海上油气资源调查的一种快速、经济而有效的手段.更多还原

【Abstract】 3 apparent mercury anomalies attibutable to both atmospheric and seawater mercury are identified, during a mercury content survey of bothsea-surface atmosphere and superficial water column in Lile bank area.The anomaly Ⅰ and the anomaly Ⅱ are probably related to hydrocarbon occurrences there. The anomaly Ⅲ neverthelessis believed to reflect major deep-deated faults. This study suggests that offshore mercury content survey of this kind might be a rapid and cheap means to investigate offshore petroleumresources.更多还原
