摘    要:基于中国大洋36和41航次浅地层剖面数据,结合DSDP钻井及国内外相关研究,对西太平洋维嘉平顶山顶部沉积物的浅地层剖面特征、沉积环境、沉积时代、沉积物厚度分布特征等进行了研究,发现3种主要的地层反射特征,分别代表3个沉积单元;山顶沉积物的厚度分布呈现出3个沉积中心区和4个基岩裸露/沉积物稀薄区的特点;平顶山东部的沉积异常可能与始新世的第二次火山活动有关。根据富钴结壳的生长和发育特点,结合维嘉平顶山的沉积物分布特征,圈定了结壳资源潜力分布区。维嘉平顶山作为中国重要的富钴结壳合同区块,本次研究对其富钴结壳资源进一步的勘探工作具有指导意义。

关 键 词:西太平洋  维嘉平顶山  浅地层剖面  沉积特征  富钴结壳

Abstract:Based on the subbottom profiles,DSDP drilling and related studies,the authors studied sedimentary environment,deposition history,sediment thickness and cobalt-rich crust resource potential of Weijia Guyot in the Western Pacific Ocean.The main conclusions are as follows:there are mainly three types of reflection characteristics on the top of the Weijia Guyot,which represent three sedimentary units;there are three depositional centers and four depositional rarefaction areas on the top of Weijia Guyot,and dcpositional rarefaction or basement outcrop areas have good crust metallogcnic conditions;the depositional anomaly area in the eastern center was related to the second volcanic activity during Eocene.This study has a very important guiding significance for the future exploration of cobalt-rich crust resources on the Weijia Guyot.
Keywords:Western Pacific Ocean  Weijia Guyot  subbottom profile  sedimentary characteristics  cobalt-rich crust
