Study on the phosphorate minerals assemblage shows that strongly developed anatexis of the area is responsible the occurrence of wagnerite and its coexistence with apatite, and both present as rock-forming minerals. The volatiles F, P and components Ca, Mg determine the formation of wagnerite, while the P-T condition affects the variation of wagnerite polytypes.

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。

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

In the condition of keeping F、 K、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.

2对测定粘度的冷凝渣所进行的X粉晶衍射及显微分析和鉴定表明，增加MgO含量，渣中枪晶石将减少甚至消失，而钙镁橄榄石则随MgO含量增加而增加，在／SiO〓不变时，黄长石含量也有所增加，高熔点矿物的出现和增加，提高了含氟熔渣的熔化性温度；加入TiO〓熔渣中将形成高熔点矿物-钙钛矿，钙钛矿的形成还促使黄长石的结晶，这是TiO〓提高含氟熔渣熔化性温度的根本原因。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

Therefore, its U-Pb ages are likely to yield the age of metamorphic crystallization rather than resetting by simple diffusion, such that metamorphic titanite may preserve complicated U-Pb system that contains information of the whole metamorphic history of the rock, which can be revealed by in situ U-Pb dating, e.

由于榍石的组成元素均为岩石中的主要元素，很容易与其它矿物、熔体及流体发生反应，所以榍石的U-Pb年龄记录的更可能是结晶年龄，而不是简单的扩散重置年龄；也因为它容易反应，变质榍石复杂的U-Pb体系可能记录了岩石的整个变质历史信息。
