摘要
本文主要在前人研究的工作基础上,对华北克拉通(中朝克拉通)和华南地区产出的下地壳麻粒岩捕虏体的研究进展及其地质意义作一简要综述。文中共涉及8个方面:①基本情况;②国内外研究现状;③麻粒岩捕虏体的产出特征;④麻粒岩捕虏体的岩石类型,伴生的地幔岩、共生矿物组合、温压条件;⑤麻粒岩捕虏体的原岩年龄和变质年龄;⑥麻粒岩捕虏体的岩石化学和地球化学特征;⑦华北和华南麻粒岩捕虏体所代表的下地壳位置;⑧麻粒岩捕虏体同位素年龄的地质意义和麻粒岩捕虏体的成因。并提出了4个科学问题和今后工作的建议。
Based on previous researches,this paper chiefly summarized some progresses made in the study of continental lower crust granulite xenoliths in North China Craton（Sino-Korean Craton） and South China region as well as their geological significance.Eight aspects are dealt with in this paper： ① general situation;② current researches conducted both in China and abroad;③ modes of occurrence of granulite xenoliths;④ rock types,associated mantle rocks,mineral assemblages and p-t conditions of granulite xenoliths;⑤ dating of original rock age and metamorphic age;⑥ petrochemistry and geochemistry of granulite xenoliths;⑦ lower crust position in North China Craton and South China region represented by granulite xenoliths;⑧ geological significance of isotope ages and genesis of granulite xenoliths.Four scientific problems and some suggestions concerning further studies are also put forward in this paper.
