Clinoclasite, olivenite, cornwallite, cornuhite, conichalcite, adamite, duftite, hayldonite, mimetesite, carminite, dussertite, scorodite, Ba-bearing pharmacosiderite and heudanite. The physical properties, optical constants, chemical composition, X-ray data, infrared absorption spectra and differential thermal analyses of the minerals are given in this paper, which serve as a sheet of fairly perfect data for arsenate minerals in China.

是有疑义的矿物；而光线石、墨绿砷铜石、羟砷铜石、乳砷铅铜石、砷铅铁石、绿砷钡铁石及含钡毒铁石等是在国内首次发现的矿物；橄榄铜矿、砷铅石等在国内未见有其矿物学数据的公开报导。

As a common secondary mineral, feldspar minerals, especially albite, have shared a close relationship with jadeite minerals.

长石矿物特别是钠长石作为翡翠的常见次要矿物，与硬玉矿物之间存在着密切的关系。

Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。

High salinity fluid inclusionscontaining daughter minerals have been found in quartz and ankerite of main mineralizingstages, Taibai and Baguamiao gold deposits of Shaanxi province, located in South Qinling.Both deposits occur in Devonian low-grade metamorphic rocks. Daughter minerals weredetected as pyrite, ankerite, halite and arsenopyrite by SEM/EDS and EPMA.

对赋存于南秦岭泥盆系浅变质碎屑岩中的陕西太白金矿、凤县八卦庙金矿主成矿阶段的石英和含铁白云石中的流体包裹体进行研究，发现局部富含高盐度、含子矿物的流体包裹体，通过光学显微镜、电子探针、扫描电镜/能谱发现子矿物主要为黄铁矿、铁白云石、石盐、毒砂及一些成分复杂的子矿物。

Finally, the paper makes a preliminary discussion on the formation conditions of arsenate minerals.

文章提供了这16种砷酸盐矿物的矿物学参数，并对该类矿物的形成条件进行了初步的探讨。

The monocrastal minerals of gold are native gold, calaverite and electrum. Besides the native gold, pyrites and pyrrhotites are main auriferous minerals, inside which the aurum are in the form of fracture aurum, intercrastalline aurum and aurum inclusions.

Au的独立矿物主要为自然金、碲金矿和银金矿，金除了自然Au之外，黄铁矿和此黄铁矿是主要载金矿物，在载金矿物中Au主要呈裂隙金、晶间金和包体存在。

Using optical microscope, manual artificial heavy concentrate, electron microprobe and scanning electron microscopy, we tested major gold- bearing minerals in Zhaishang deposit. Pyrite and scheelite are the most important gold-bearing minerals. Quartz, limonite, and chalcocite are the secondary gold-bearing minerals. Calcite, siderite, barite and other minerals do not contain any gold.

通过光学显微镜、人工重砂、电子探针、扫描电镜等显微测试手段对寨上矿区主要载金矿物进行分析测试得出：黄铁矿、白钨矿是最主要的载金矿物之一，石英、褐铁矿、辉铜矿是次要的载金矿物，方解石、菱铁矿、重晶石等不含金。

Through micro-test ing technologies such as optical microscope manual artificial heavy concentrate electron microprobe and scanning electron microscopy major gold-bearing minerals are tested in Zhaishang deposit. Pyrite and scheelite are the most important gold-bearing minerals. Quartz limonite and chalcocite are the secondary gold-bearing minerals.

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。
