摘要:
蛇绿岩概念自上世纪70年代提出以来,就成为确定古板块边界的重要证据,具有重要大地构造学意义,一直是地质学家研究的热点之一。近年来,随着地球化学技术的发展以及深海钻探计划和大洋钻探计划的实施,世界各地蛇绿岩研究不断深入,取得了很大的发展,同时也提出了很多新的问题。本文主要论述了蛇绿岩研究的最新动态,并对华南蛇绿岩的研究进展进行了分析梳理,对存在的一些问题作了初步讨论。
Abstract:
Ophiolite is an important evidence to determine the palaeo-plate boundaries and shows an important geotectonic significance since 1970s,thus when the concept of ophiolite was proposed,it has become one of the most important object of study for geologists.With the development of geochemical techniques and implement of deep sea drilling program(DSDP) and ocean drilling program(ODP),further studies on ophiolites have been made and a great progress has been acquired in recent years,however many new problems have been raised at the same time.This paper mainly discusses the recent development in the study on ophiolites and analyzes the present situation of researches on ophiolites in south China.In addition,some existed problems have been preliminarily discussed.
