  modification level
This paper presents a method known as image-analysis-based silicon modification level, which provides highly reliable results to determine the level of silicon modification for Al-Si hypoeutectic and hypereutectic alloys.
      
It cannot be used to evaluate the aluminum-silicon eutectic modification level on-line.
      
It should be emphasized that the very small amount of the modification level seems enough to enhance the cellular uptake efficiency.
      
Laboratory validation should ideally use an alternate method of quantification of the DNA modification level.
      
This work presents a methodology for the quantitative assessment of the aluminum-silicon eutectic modification level using thermal analysis technique.

The gold-bearing quartz veins are mainly located in two stratigra-phic units in Xiaoyingpan gold deposits, the first is light-coloured granulite group, and the second is dark-coloured granulitite group. The geochemical character of metavolcanics has shown that their most favourable tectonic environment was an arc-island model. The structural control over the ore deposits was a thrust in the limb of the overturned syncline. The host rocks were metamorphosed to the amphibolite and granulite facies. The percentage...

The gold-bearing quartz veins are mainly located in two stratigra-phic units in Xiaoyingpan gold deposits, the first is light-coloured granulite group, and the second is dark-coloured granulitite group. The geochemical character of metavolcanics has shown that their most favourable tectonic environment was an arc-island model. The structural control over the ore deposits was a thrust in the limb of the overturned syncline. The host rocks were metamorphosed to the amphibolite and granulite facies. The percentage of gold, was calculated based on the physical-chemical conditions. In contrast to foreign gold deposits, the deposits were formed in near surface conditions.

小营盘金矿床的含金石英脉主要赋存在两个地层单位中,第一个是浅色的麻粒岩段,第二个是暗色的变粒岩段。变火山岩地球化学特征表明,它们生成的最有利的构造环境是岛弧模式;控矿构造是倒转向斜翼部的冲断层;容矿围岩变质级别达到角闪岩相和麻粒岩相。根据物理化学条件所计算的金的成色与国外金矿床相比,该矿床是近地表条件下形成的。

The Fuping gneiss complex consists mainly of the grey gneisses which are interlayered with small amount of amphibolite and metavolcanic and meta sedimentary rocks. On the basis of the REE data, the Fuping grey gneisses can be divided into two types. The REE pa+-terns of the first type show less fractionation with a prominent negative Eu anomaly. The REE patterns of the second one show highly fractionation with no prominent Eu anomally. Both types could be derived from partial melting of mafic source rocks, but...

The Fuping gneiss complex consists mainly of the grey gneisses which are interlayered with small amount of amphibolite and metavolcanic and meta sedimentary rocks. On the basis of the REE data, the Fuping grey gneisses can be divided into two types. The REE pa+-terns of the first type show less fractionation with a prominent negative Eu anomaly. The REE patterns of the second one show highly fractionation with no prominent Eu anomally. Both types could be derived from partial melting of mafic source rocks, but have different mineral phases in the residue. In the first case, the residue consists mainly of plagioclase; in the second case, the most mineral in the residue is amphibole. It is supposed that the latter is related to the total pressure under which the protolithic magma might be derived. At relatively low pressure the residue contains mainly plagioclase; at relatively high pressure the residue contains mainly amphibole. Thus, the protolith of the Fuping grey gneisses might be produced in the different crustal levels corresponding to different total pressures.

The muscovites from Precambrian metamorphic rocks in Wutai Shan belong to the 2M-polytype of dioctahedrom: those from Wutai group are common muscovites rich in celedonite and those from Hutuo group are phengite. By measuring the chemical composition and b_0 value of the muscovites,it is determined that the metamorphic conditions of Wutai group belongs to midlow pressure phase series and that of Hutuo group belongs to mid-high pressure phase series. The matamorphic pressure of greenschist phase of the Wutai group...

The muscovites from Precambrian metamorphic rocks in Wutai Shan belong to the 2M-polytype of dioctahedrom: those from Wutai group are common muscovites rich in celedonite and those from Hutuo group are phengite. By measuring the chemical composition and b_0 value of the muscovites,it is determined that the metamorphic conditions of Wutai group belongs to midlow pressure phase series and that of Hutuo group belongs to mid-high pressure phase series. The matamorphic pressure of greenschist phase of the Wutai group was of 0. 3-0. 5 Gpa and the Hutuo group of 0. 5-0. 6 Gpa. Based on studying the chemical composition and b_0 values of muscovites, it may help to determine the metamorphic grade and type,the metamorphism stage and work on the strata correlation and the regional structural analysis.

五台山早前寒武纪变质岩中的白云母属二八面体的2M型多型变体,其中五台群中的白云母为富含绿鳞石分子的普通白云母,滹沱群为多硅白云母。通过对这些白云母化学成分和b_0值测定,确定五台群变质条件属中低压相系,滹沱群属中高压相系。五台群绿片岩相的变质压力为0.3—0.5 GPa,滹沱群为0.5—0.6 GPa。基于白云母成分和b_0值的研究,对划分变质级别、变质类型;确定变质作用期次;进行地层对比和构造分析等方面是可行的。
