东坑-菖蒲地区燕山晚期脉岩地球化学特征及其成因
A discussion on geochemical characteristics and petrogenesis of the Late Yanshanian dikes in Dongkeng-Changpu area
摘要
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 compoent. It was inferred that metallogenic fluid and matter may derived from the mantle enriched component or the low crust.关键词
