| 摘 要： | 造山带复杂地壳组份区的花岗岩成因类型研究倍受关注。本文从岩石化学、微量元素、稀土元素,稳定同位素等方面论述了西泰岭造山带内的沈坪地区花岗岩的成因特征,认为其成因属以S型为主并表现出大量Ⅰ型的复杂类型。文中还就其形成原因以及成因类型与构造活动演化的关系做了初步探讨。

| Abstract: | Special attention has been paid to the study on the genetic types of granites in the region with complicated crustal constituents within orogenic belt. This paper discusses the genesis of granites in Taoping region withein western Qinling orogenic belt in forms of petrochemistry minnorelements,REE and stable isotopes etc. It is considered that they have complex gentic types dominoded by S-type with I-type. The genesis and relationship between genetic types of granites and tectonic evolution are also discussed. |
