orthomagmatic deposit

All possible kinds of ore deposits including magmatic deposits connected directly with the mantle plume and indirect deposits due to crust response have been discussed.

概述了峨眉山地幔柱成矿作用的基本类型和主要特点,对主要成矿类型包括地幔柱活动直接形成的岩浆矿床和地壳响应形成的间接矿床作了全面的分析介绍,初步勾画了峨眉山大火成岩省地幔柱成矿作用的基本框架。

But superlarge and large magmatic deposits have been discovered in many small intrusions.

我国没有发现与巨型层状岩体有关的岩浆矿床 ,但是在许多小岩体中 ,却发现了超大型和大型的岩浆矿床 ;提出了小岩体岩浆矿床是今后一个重要的研究和勘查方

AH possible kinds of ore deposits include magmatic deposits connected directly with mantle plume and indirect deposits of response in the crust have been discussed.

本文概略的阐述了峨眉山地幔柱成矿作用的基本类型和主要特点,对主要成矿类型包括地幔柱活动直接形成的岩浆矿床和地壳响应形成的间接矿床作了全面的分析介绍,初步的勾画了峨眉山大火成岩省地幔柱成矿作用的基本框架。

The application of the Re-Os system into the typical magmatic ore deposits hasindicated the complex ore-forming sources for this type of deposits which used to be con-sidered to have been solelv derived from the mantle, The analvtical results from importantdeposits such as Bushveld,Sudbury,Noril'sk imply that they have a considerable portionof the crustal materials.

近几年以来，由于铼－锇同位素体系逐渐应用于基性－超基性岩有关的岩浆型矿床中，对这类矿床的成矿物质来源有了更为深刻的认识。
