The petrogenesis of intrusive rocks is discussed in this paper according to the equilibrium of minerals. It is suggests that in the Shigujian pluton, the designations of plagioclases are 15 - 25, the plagioclases are all oligoclase; the biotites are Mg-biotites, and most of the amphiboles are edenitic amphiboles or edenite; paragenetic ...

结果表明：（1）石鼓尖侵入岩中，斜长石成分较稳定，共生角门石和黑云母为岩浆平衡结晶的矿物；（2）天堂寨和九资河侵入岩中，部分斜长石和黑云母可能为熔蚀残留矿物，角闪石属于火成岩区的新生矿物，可能为斜长石和黑云母发生熔融反应所形成；（3）三个侵入体的岩石均为岩浆成因。

40Ar-39Ar method is the first one of the possible geochronology techniques to solve this difficult scientific problem.

油气成藏作用伴生的矿物种类少，主要为碳酸盐矿物，以及少量石英和黄铁矿等，这些矿物均不适合用传统同位素年代学方法进行年龄测定，因此，油气成藏年龄是同位素年代学尚未解决的一大科学难题。40Ar-39Ar法是可能应用于油气成藏年龄测定的首选同位素定年方法。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

Mineral magnetic parameters, including magnetic susceptibility, frequency dependent susceptibility, isothermal remanent magnetization, anhysteretic remanent magnetization, temperature-dependence of susceptibility, were measured on quartzite and surface soil derived from quartzite. The results in combination with the microscope observation indicated little magnetic mineral in quartzite but a few magnetite, maghemite, iron oxyhydroxides in surface soil. The magnetic grains were mainly superparamagnetic and stable single domain. Maghemite is secondary mineral formed in the process of pedogenesis.

通过对石英岩及发育于石英岩之上表土的磁化率、频率磁化率χ(下标 fd、等温剩磁、非磁滞剩磁ARM0、k-T曲线等磁学参数测定和石英岩显微镜下观察，结果表明，石英岩中磁性矿物含量极少；表土中含磁铁矿、磁赤铁矿、铁的氢氧化物等磁性矿物，磁性矿物主要以稳定单畴(SSD和超顺磁性颗粒形式存在，磁赤铁矿是石英岩在成土过程中形成的次生矿物。

It is considered that these materials are derived from different sources: calcite comes from cigarette paper, whewellite is crystallized during the growth of tobacco leaf itself, and gypsum is formed in the combustion process of cigarette.

这些矿物具有不同的来源：方解石来自卷烟纸，一水草酸钙石是烟叶生长期间自身合成的矿物，石膏是香烟燃烧过程中新形成的矿物。

The effects of sintering temperature on the petrographic structure, mineral composition, crystalline phase and solid solubility solution composition of clinkers were studied by means of microscope, XRD, EDS and chemical analysis.

检测了不同烧成温度制成的低热水泥的物理性能及水化速率，并采用岩相分析、XRD、EDS﹑化学分析方法研究了不同烧成温度对低热水泥熟料岩相结构﹑矿物组成、矿物晶型及矿物固溶组分的影响。

No report about the analogous object in meteor ite has been seen, The mineral constituents of the vein are quartz, muscovite, illite (which was discovered firstly in meteorites), chlorite and some opeque minerals.

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。
