摘要
造山带火山岩石学研究的主要目的在于重溯造山带的构造 -岩浆演化历史。纵观我国以至全球的大陆造山带形成、演化历史 ,一个造山带往往经历了古大陆裂解、洋陆转换、陆块拼合—碰撞、陆内伸展—盆山耦合和新构造隆升 (陆内造山 )等众多不同的构造演化阶段 ,这些不同的构造演化阶段和不同的构造环境均有特定火山岩浆作用与之相伴。因此 ,可以根据造山带形成、演化不同阶段火山岩浆作用的特点来重溯造山带的构造 -岩浆演化历史 ,进而从更大尺度上加以对比 ,探索全球动力学乃至比较行星动力学等重大科学问题。本文对造山带火山岩石学研究中的一些重要问题进行了讨论和评述 ,这些问题包括 :板块内部火山岩浆活动、离散板块边界上的火山岩浆活动。
The study of volcanic rocks in orogenic belts aims mainly at retracing the tectono_magmatic evolutionary history of orogenic belts. A general survey of the formation, evolutionary histories of continental orogenic belts both in China and abroad reveals that orogenic belts have often undergone numerous and varied tectono_evolutionary stages, such as palaeocontinental break_up, ocean_land transition, continental matching_collision, intracontinental extension-basin_range coupling, and new tectonic uplift (intracontinental orogeny), which are respectively accompanied by characteristic volcano_magmatisms. We might therefore retrace the tectono_magmatic evolutionary history of orogenic belts in the light of characteristics of volcanic magmatism at different forming and evolutionary stages of orogenic belts and further explore some important scientific problems of global dynamics and comparative planetary dynamics by means of comparison on larger scales. Some important problems on the study of volcanic rocks of orogenic belts, which include volcanic magmatism within the plate, volcanic magmatism at constructive plate margins and volcanic magmatism at destructive plate margins, are discussed and reviewed in this paper.
