According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

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。

In this paper, by analysis of reservoir characteristic, lithology, sedimental environment and geological feature of Putaohua oil layer in Fang 3 area Songfangtun oilfield, Songliao basin, the authors discuss reservoir characteristics and its influence factors. Feldspathic sandstone and detritus sandstone are the main type of reservoir which is lithology has siltstone, fine sandstone etc.

摘 要：通过对松辽盆地宋芳屯油田芳3区块葡萄花油层砂岩储层岩性、物性、沉积环境及地质特征的研究，对葡萄花油层砂岩储层的物性特征及其影响因素进行了系统的分析，认为长石砂岩和岩屑质长石砂岩是主要砂岩类型，岩性有粉、细砂岩等，但以粉砂岩为主。

Danfengchang formation Xujiahe reservoir thickness is 460-500m, the lithological character is feldspathic lithic quartzite sandstone, feldspathic quartzite sandstone and lithic quartzite sandstone in the formation of Xujiahe.

丹凤场构造须家河组地层厚度为460-500m，须家河组储层岩性主要为长石岩屑石英砂岩、长石石英砂岩和岩屑石英砂岩。

The gold deposit is closely associated with the feldspathic quartz gray-wacke of the Zhuanqiangwan Formation of the Furongxi Group and the pebble-bearing feldspathic quartz gray-wacke of the Sinian Changtan Formation.

芙蓉溪群砖墙湾组长石石英杂砂岩和震旦系长滩组含砾长石石英杂砂岩均具明显的控金作用。砂岩层往往大面积发生矿化蚀变，矿体严格受砂岩层控制。

Lithologically, the content quartz is lower than those of feldspar and detritus, and the cement is dominated by clay, which gives the feature of low compositional maturity and low textural maturity.

馆上段储层岩性以岩屑质长石细砂岩为主，其次为中细砂岩和粉砂岩，岩石中石英含量低，而长石、岩屑含量高，胶结物以泥质为主，表现出低成分成熟度和低结构成熟度的特点。

We suggest that the shocked meteorites could be classified into two groups; the group-A contains high-density phases, such as maskelynite and other high-pressure minerals; the group-B contains low-density phases, for instance diaplectic feldspar glass, molten glass and the assemblages of low-pressure minerals.

本文提出，陨石按照冲击变质特征可以划分为以下两类：一是含高密度相类，如熔长石和各种高压矿物；二是合低密度相类，如长石击变玻璃、低压熔融玻璃和低压矿物组合。

Crystal structure of melilite is limited by MgO content of glazes, also restricted by O/Si ratio. Because of differences of ionic radius and ionic polarization capacity between Ca〓 and Mg〓, suitable O/Si ratio for melilite is influenced by content of CaO and MgO to a certain extent.

结晶釉中黄长石结构的出现，除了和MgO含量相关外，还受O/Si比值的限制；而Ca〓和Mg〓离子半径和离子间的极化能力的差异，使钙镁含量对形成黄长石结构的O/Si比值具有一定的影响。

Associations of phases include cyclowallastonite and wallastonite, wallastonite and clinopyroxene, clinopyroxene and melilite, wallastonite and clinopyroxene and melilite, cyclowallastonite and clinopyroxene.
