摘要
在藏北丁固地区,变质岩广泛分布,主要为区域变质岩,少量接触变质岩、混合岩化变质岩及动力变质岩。变质类型、变质岩相及变质岩石组合的空间分布等,受地层时代、原岩性质、地质构造及中酸性侵入岩体等多重因素控制。本文初步建立其综合模式。
At Dinggu there are widespread metamorphic rock in distribution dominated to regional metamorphic rock, with a small amount of contact metamorphic rock, migmatization metamorphic rock and dynamic metamorphic rock. Metamorphic types, lithofaeies and spatial distribution of metamorphic rock are under control of ages of beds, attributes of primary rocks, geologic structure and neutral - acid intrusive rocks
