According to the experimental results of Watson (1978), and Ryerson and Hess (1980), pertaining to the distribution of trace elements between basic and acidic liquids in the temperature above magmatic liquidus, and the investigation of Webster (1997) on the melt inclusion in pegmatitic quartz from Ehrenfriedersdorf ore district, Germany, it should be drawn that there probably exists the liquid immiscibility in the early stage of pegmatitic evolution, due to the perphosphorus content in the magmatic systems. The perphosphorus feature of the melt is of great impact on the petrogenesis and matellogenesis of pegmatites.

Acid-fracturing treatment and testing technology level have great impact for testing production. The reservoir can be damaged easily and the uncertainty for calibrating log interpretation will increase according to testing conclusions.⑶ Lithology complex (quartz sandstone, lithic sandstone, arcose), the reservoir has different characteristics with different lithology. Conventional log interpretation methods can not accurately identify the various sandstone.

酸化压裂和试油工艺水平对测试产能的影响很大，储层容易被伤害，使根据试油气结论进行测井解释标定的不确定性增大；⑶岩性（石英砂岩、岩屑砂岩、长石砂岩）复杂，不同岩性的储层具有不同的特征，常规测井解释方法无法准确的识别各类砂岩岩性等。

Inside the rock body of Rose Stone, in addition to rosy red rhodonite, it also includes tawny and grayish white manganese pyroxene, pink manganesite, black soft manganese mine, other quartz, and dolomite minerals etc.

玫瑰石的岩体内除具有玫瑰红色的蔷薇辉石外，还间夹了黄褐色和灰白色的锰辉矿、粉红色的菱锰矿、黑色的软锰矿，以及其他石英、白云石等矿物。

Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.

说明早期成矿流体为富含CO〓、H〓O等的碱性流体，其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源，带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化，带出的Na〓则在浅部形成钠长石脉。

This paper reports the results of highly precise zircon SHRIMP U-Pb dating of quartz albitite in the volcanic-sedimentary series of the Tuolugou cobalt deposit, Golmud, Qinghai. Analyses of eight spots presented 206Pb/238U ages of 455 to 483Ma with a weighted mean age of 468±9Ma, which represents the timing of submarine volcanic exhalation in this area. Therefore, the age of the host rocks of the Tuolugou ore district is redefined as Ordovician, which implies that regionally the main part of the Naij Tal Group should be Early Paleozoic in age.

青海格尔木驼路沟矿区赋矿火山－沉积岩系中的石英钠长石岩样品锆石SHRIMP U-Pb精细测年结果表明，该岩石具有一组8个测点构成的455~483Ma的206Pb/238U年龄数据，加权平均年龄为468Ma±9Ma，应代表本区海底火山喷流作用的时间，因此重新厘定了矿区内含矿岩系的时代为奥陶纪，同时，这一年龄指示区域上纳赤台群主体的时代应为早古生代。

Formation of augen fabrics is decided by the ductile deference between the porphyroblast and matrix in deformation rock.

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

It indicated that, brecciated granodiorite was foemed mainly by chemical attack, brecciated ore and brecciated marble were hydraulic breccias which were formed mainly by mechanical process, and the energy when brecciated ore was formed is higher than the energy when brecciated marble was formed.During the research of tectono-geochemistry in the south part of Fenghuangshan copper deposit, it is discovered that the fractal character of Cu is multifractality, and different from each other according to the geological bodies.

凤凰山铜矿床南区构造地球化学取样分析中的Cu元素含量具有多重分形的特点，且不同的地质体中其分形特征不同，结合Cu元素在不同地质体中的分布特点，说明本区不同地质体所经历的成矿作用不同，其中以石英二长闪长岩所经历的成矿作用强度较大，较有利于成矿元素的富集。

One is that,by the shove of passive rift valley polycycle,quartz sandstone with high maturity of lithologic composition deposits on the background of sub-plain during sag period;together with the rock formation environment of paranormal saltless local water,the reservoir characterized b.

厘定该盆地这种突出商业价值的地质因素主要表现在以下两个方面：1被动裂谷的多旋回推移，在坳陷期的准平原背景下沉积了高岩石成分成熟度的石英砂岩，加之超淡地层水的成岩环境，最终形成盆地的高孔高渗储层；2&教科书&式的生储盖组合。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
