| 摘 要： | 大兴安岭地区酸性岩发育、中性岩次之，中酸性岩不发育，基性－超基性岩极少见，酸性岩富硅、高钾、贫铁镁，成因主要属陆壳改造型。据此，本文认为该区岩浆岩是－套富锡、铅锌（银）而贫铜岩浆的产物，并认为在此区找大型铜矿必须综合考虑岩浆岩与矿源层的成矿条件。

| Abstract: | The Daxinganling region is petrologically characterized by the dominance of deve1OPed acid rocks,subdominance ofdeveloped medium rocks and not well development of medium-acid rocks, rare occurrence of basic-- -- ultrabasic rocks, as wellas enrichment of Si-K and lack of Fe-Mn. These factors indicate that they are petrogenetically of reformed continental crusttypes and that they are the products of magma with riched Sn, Ph, Zn and lacked Cu. It is propused that the importance shoud benecessarily attached to the comprehensive metallogenlc conditions of magmatics and some source beds for the prospecting of large-sized copper deposits in this region. |
