网络释义

用法例句

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 analysis results show that there are two types of zircons from the Danzhu granodiorite:magmatic zircon and metamorphic zircon.

研究结果表明,该花岗闪长岩中存在两种不同类型的锆石:岩浆锆石和变质锆石。

In the end,the author get a conclusion that magmatic zircons with simple composition are ideal minerals for zircon U-Pb dating.

笔者认为,组成单一的岩浆锆石是理想的U-Pb定年对象,变质重结晶锆石域常是重结晶锆石和继承晶质锆石的混合区,容易给出混合年龄,只有变质增生锆石和完全变质重结晶锆石才能给出准确的变质时代,而从继承锆石中鉴别出的热液锆石可以获得可靠的流体活动时间。
