| 摘 要： | 利用大量的海底沉积物样品，开展了东海天然气水合物卫星热红外遥感和沉积物酸脱气地球化学找矿研究。根据卫星热红外增温异常和海底浅表层沉积烃类异常及其他各种异常标志，可以预测冲绳海槽中南部海域为最可能的水合物赋存区。

| Abstract: | Gas hydrate or hydrate, a kind of solid crystal matter composed of water and hydrocarbon under the low temperature and high pressure conditions, is taken as a future energy or energy in the 21st century.At present,it is commonly believed that there exist abundant hydrates in the offshore deep water sediments of China. However, as far as the East China Sea is concerned, little work is done on gas hydrate except for some preliminary discussions. In recent years, with the support of the relevant units and partners, we have got a large quantity of sediment samples, and carried out researches of satellite based thermal infrared remote sensing and acid degassing hydrocarbon geochemistry possibly related to gas hydrate.In this paper, based on the analyses of geological settings as well as the previous data, the middle and south parts of the Okinawa Trough are considered a good potential area for gas hydrate occurrence. |
