摘要
依据同源岩浆演化理论和花岗岩类岩石等级体制的划分,将青海省侵入岩划分为13个构造岩石区;划分了108个超单位、117个(命名)单元(含7个独立单元)、255个岩性单元及数十个类型的年代加岩性侵入体。全省侵入岩成因初步分为幔源型、壳幔混合型、壳源深部型、壳源浅部型和浅壳源型;其分别形成于裂谷、深部裂冲、板块俯冲、板内挤压、板块碰撞及造山期后抬升环境。
In the term of the theory of comagmatic evolution and dividing system ofgranitoid rocks the intrusive rock in Qinghai province can be divided into 13 tecto-petrologicarea, 108 super-units, 117(named) units (include 7 independent units), 255 lithologic unitsand dozens of chronolithologic instrusive bodies. The origin of the intrusive rocks are respec-tively belonged to mantle type, crust-mantle type,deep crust type, shallow crust type, andshallow type. They formed separately in such tectonic setting as rift, deep rift-thrust, platesubduction,intraplate compression, plate collision and post-orogenic uplift.
