1986年9月2—13日在新西兰库克群岛的腊罗汤加举行第十五届南太平洋CCOP会议,与会的除南太平洋十三个成员国代表外,尚有中国、美国、苏联、日本、英国、法国、联邦德国、加拿大、挪威等国代表作为技术顾问组的身份参加,中国地质矿产部派出蒋敏喜和金庆焕两位同志赴会.现将此次会议所交流的海洋地质调查资料作一简要的汇报,以供国内同行参考.南太平洋CCOP成员国及其附近海域处于太平洋、欧亚和印度—澳大利亚三大板块的结合部位,其边缘地带组成多种类型的沟、弧、盆体系,地质构造极为复杂.另在南太平洋海域分布有翁通—爪哇等海台,因其地壳较厚而显然属于巨大的陆块,这些陆块为持板块构造观点的人们所不解,因而早已为地质学家所瞩目.南太平洋海底蕴有较丰 The 15th South Pacific CCOP Conference was held on September 2-13, 1986, in Larong Tonga, Cook Islands, New Zealand. In addition to the representatives of thirteen member countries of the South Pacific, there are also representatives of China, the United States, the Soviet Union, Japan, Representatives of the United Kingdom, France, the Federal Republic of Germany, Canada and Norway attended the meeting as representatives of the technical advisory group, and the Chinese Ministry of Geology and Mineralism sent two comrades Jiang Minxi and Jin Qinghuan to attend the meeting. Brief report for reference of domestic counterparts.The South Pacific CCOP member and its adjacent waters are in the combination of the three plates of the Pacific Ocean, Eurasia and India-Australia, and their margins are composed of various types of ditch, arc and basin systems, The geological structure is extremely complicated.Otherwise in the South Pacific Ocean, there are Wengtong-Java and other offshore platforms. Because of their thick crust, they are obviously huge land masses which are unknown to the people who hold plate tectonics. Geologists have attracted the attention of the South Pacific Ocean
