| 摘 要： | 本文以东坑-菖蒲地区发育的燕山晚期脉岩为对象,阐述了其岩石学和地球化学特征,并结合脉岩产出的大地构造背景,对其成因进行探讨。认为中基性脉岩为岩浆快速上升侵位所形成,其岩浆来源于地幔混染端员,源区受到富集地幔流体的交代作用;酸性脉岩具A2型花岗岩特征,岩浆源区较深,以地壳组分为主,受到富集地幔组分混染;推测该区部分铀成矿流体和成矿物质来源于地幔或下地壳。

| Abstract: | The paper studied the characteristics of Late Yenshanian dikes in Dongkeng-Changpu area in petrology and geochemistry and discussed its origin in the tectonic setting.It was believed that the intermediate basic dikes was the rapidly emplaced magama which was originated from the contaminated chamber metasomatized by the fliud enriched mantle and the acidic dikes is with the characteristics of A2-type granitoids,and the magma was formed in the deep with crustal major contaminated by the mantle enriched compoe... |
