矿物学在环境科学中的应用将是21世纪矿物学研究的一个主要方面。

Nowadays, the application of mineralogy in environmental sciences is a major aspect of mineralogical studies.

矿物学在环境科学中的应用是当前矿物学研究的一个主要方面，矿物-水界面反应对环境中物质的循环和元素的地球化学过程起着十分重要的作用。

In terms of environmental mineralogy, the application of nonmetallic and metallic minerals to contamination control and environmental protection is summarized in this paper.

简述了环境保护的紧迫性，从环境矿物学角度综述了矿物或经改性的矿物，在环境污染控制和环境修复中的作用及其应用现状，并简要分析了矿物材料在环保方面的应用前景。

The composi-tion of the seawater has changed rapidly since Phanerozoic, and the prolonged mineralogical changes of marine non-skeletal limestone and potash evaporates occurred in a phase on a 100-200 Ma.

结果表明：显生宙以来海水组分发生变化，经海相非骨骼灰岩和钾盐蒸发岩矿物学研究，发现这两种沉积岩长期以来连续变化，在"文石海"是MgSO4型蒸发盐，在"方解石海"是KCl型蒸发盐，从白垩纪晚期、第三纪早期的底部石盐溴含量及矿物学特征表明，此时处于"方解石海"，古海水组分的特点是造成缺硫酸盐型钾盐矿床形成的物化基础；通过NaCl-KCl-MgCl2-H2O和NaCl-KCl-MgCl2-CaCl2-H2O两个体系相图的分析认为，当时所形成的成钾原始体系母液是高镁、低钾氯化物型的卤水，在母液蒸发过程中，由于原始海侵母液与残余高镁母液的掺杂作用，致使结晶路线直接从氯化钠区到E点母液或光卤石与氯化钠共饱线上，而没有通过氯化钠和氯化钾的共饱线，因而在矿体中氯化钾相很少或几乎不存在，由于外界CaCl2型水体的掺杂，使成钾母液进入光卤石相区，随着蒸发的进行，最终形成溢晶石矿物。

The first method is not related to petrogenesis, but welcomed by its benefit in field work and basic petrology research; the second method reflects magma sources and tectonic environment, which has always been considered to be very important since proposed, especially a steady flow of A-type granite result in recent years; the third method, often used by researchers, consists of information about mineralogy, petology and magma source; the last method is characterized for its simple and uniform classification criterion, as well as strong operability.

矿物学－岩石学分类不涉及成因信息，比较适用于野外工作以及最基本的岩石学研究；ISMA分类的标准反映的是岩浆源区和构造环境，自提出后备受重视，尤其是A型花岗岩的研究成果近来大量涌现；Barbarin的综合性分类包含了矿物学、岩石学和岩浆源区的信息，也受到一定的推崇；Frost的地球化学分类标准统一，具有很强的操作性。

The results of process mineralogy showed that copper mineral of zinc-lead-copper complex sulphide ore existes as chalcopyrite,aftonite-binnite,polybasite and boumonite;and it was relied mainly on chalcopyrite and then aftonite-binnite.

工艺矿物学研究结果表明会理锌矿含铜的铅锌硫化矿中铜矿物以黄铜矿、银黝铜矿-砷黝铜矿、硫锑铜银矿、车轮矿等矿物形式存在，并以黄铜矿为主，其次为银黝铜矿-砷黝铜矿系列矿物。

Investigation of silver minerals in these ore deposits shows that the silver-bearing tetrahedrite and freibergite are among the most important or main industrial silver minerals.

按国际矿物学协会新矿物及矿物命名委员会的矿物命名原则，黝铜矿族矿物所含的Fe、Zn、Hg、Cd、Mn等不可作为矿物种的命名元素。

It must be pointed out that the silverbearing tetrahedrite and freibergite of the Caijiaying deposit have about the same iron and zinc content, but differ from the Fe_rich and Zn-poor tetrahedrite and freibergite in the Xiasai,Lamo, Mount Isa and Langdal deposits.

按国际矿物学协会新矿物及矿物命名委员会的矿物命名原则，黝铜矿族矿物所含的Fe、Zn、Hg、Cd、Mn等不可作为矿物种的命名元素。

The wave spectrum analytical result showed that this mineral is composed mainly of Ge and Al(GeO2 and Al2O3 are 39.84wt% and 49.96 wt%,respectively),and subordinately of F and SiF2O and SiO2 are 5.92 wt...

从成分上看，该矿物与目前已报道的含Al的独立锗矿物明显不同，可能为1种新的矿物，有待更全面、深入的矿物学研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
