FORMING CONDITIONS AND MECHANISM OF GAS HYDRATES IN THE BELLINSGAUZEN SEA, ANTARCTIC PENINSULA
-
摘要: 位于南极半岛西侧的别林斯高晋海是南极附近海域天然气水合物成矿的远景区域。利用现有钻孔岩心样品、地震剖面、声波等资料,从气源、稳定域、构造输导及沉积储集等方面,分析了别林斯高晋海天然气水合物的形成条件,预测了天然气水合物成矿远景区,初步探讨了其形成机理,以期能为今后南极半岛区域的天然气水合物资源调查研究提供一定的科学参考依据。Abstract: The Bellinsgauzen Sea in the west of the Antarctic Peninsula is a prospective area for gas hydrate formation in the Antarctic. In this paper, based on the existing coreing samples, seismic profiles, and acoustic wave data, the forming conditions of natural gas hydrates in the Bellinsgauzen Sea are discusseci, and gas hydrates predicted according to gas source, stability domain, structure transduction, and sedimentary accumulation. The prospecting area for mineralization is studied for exploration of the forming mechanism, in order to provide some scientific references for the investigation and research of gas hydrate in the regcon.
