摘要

摘要: 曾母盆地作为发育于古巽他陆架上的盆地,南部的古巽他河所携带的巨量沉积物和曾母盆地的陆架特征使得陆架边缘三角洲在曾母盆地南部发育成为必然。通过对曾母盆地中中新世以来陆架边缘三角洲的地震、钻井及进积特征分析,认为曾母盆地内陆架边缘三角洲的沉积形态呈分别向陆和向海减薄的楔形体,古巽他河携带多期次的沉积物向陆坡沉积过程中形成多套沉积复合体,这些沉积体由于具有良好的生储条件,因而具有重要的油气勘探价值。

Abstract: The Zengmu basin lies in the Sunda shelf. A great number of sediments brought in by the ancient Sunda River and features of Zengmu basin shelf may have made shelf-margin deltas develop in the south of the basin,and such shelf-margin deltas in the south of the Zengmu basin have also been proved through the analysis of drilling core and seismic characteristics. The sedimentary bodies in the shelf-margin deltas of the basin occur as wedges thinning towards land and sea.The sediments brought by the Sunda River formed many sets of sedimentary complexes. These sedimentary bodies have good oil and gas prospects because of good source-reservoir conditions of them.

青岛海洋地质研究所1963年始建于南京，几经迁转，于1979年正式在青岛恢复重建，时为“国家地质总局海洋地质研究所”。当前，青岛海洋地质研究所隶属于自然资源部中国地质调查局，主要承担国家基础性、公益性海洋地质调查研究和战略性海洋矿产资源调查评价任务。坚持以海洋基础地质、海岸带综合地质、天然气水合物地质、海洋油气地质、深海地质与矿产、数字海洋地质六大领域为主攻方向，不断加强发展海洋探测、数据处理、测试分析、海洋信息四项核心技术支撑能力，为我国海洋矿产资源开发、海洋环境保护、海防建设、海洋权益维护和海岸带生态文明建设、减灾防灾提供决策依据和支撑。

1979年，青岛海洋地质研究所主办《海洋地质研究》，当年出版2期内部期刊，1980年又出版4期内部期刊。1981年9月15日，宣告正式创刊，公开出版，国内外同步发行。刘光鼎院士题写发刊词，“这个刊物是海洋地质科研的百花园，也是相互沟通交流的桥梁。它以发表海洋地质各个领域及其分支科学的学术论著、科研成果，探讨海洋地质科技（定位、取样、物探、化探、分析与解释等）的发展方向，促进国内外学术交流为主要任务”。1983年，为配合东亚东南亚地学计划协调委员会（CCOP）在青岛建立“区域第四纪地质中心”，特增加刊载第四纪地质的内容，更为现刊名“海洋地质与第四纪地质”。汪品先院士说：“海洋地质和第四纪地质两个学科，在地球科学界都属于‘显学’范畴，世界上有不少脍炙人口的期刊，然而将两者合而为一的期刊，似乎只我中国独有”。

日落归山海，山海藏深意。海洋地质人在山海之间不断探索真理，探索的艰辛与成就悉数记录在了期刊之上。至今已有44卷、221期、3000余篇华章，如同年轮刻画着中国海洋地质成长史。

《海洋地质与第四纪地质》跟随青岛海洋地质研究所风雨同行——观山问海四十五载，谈古论今于洋陆间。未来，期刊还将记录她更多的探索、更多的辉煌！
