安山岩

The garnet-bearing andesite in the Aqikekule Lake area, northern Tibetan Plateau contains plenty of phenocrysts of garnet, plagioclase, hornblende and quartz.

中文摘要：阿其克库勒湖地区的石榴石安山岩含有石榴石，斜长石，角闪石和石英斑晶。

Sub-volcanic rocks include andesitic porphyrite, rhylitic porphyry, cryptoexplosive breccia as well as autobreccia etc.(2) Volcanic lithofacies——through the observation of cores, identification of thin sections and interpretation of well logs and seismic data, there are 8 kinds of lithofacies for the volcanic rocks of Yingcheng Formation are identified: fallout facies, effusion facies, pyroclastic flow facies, base surges facies, lahar facies, eruption-sedimentary facies, subvolcanic facies and extrusion facies.(3) Three types of eruption——i. e. explosion, effusion and surge.(4) Two kinds of eruptive environments——Subaerial (e. g. volcano in Well Shangshen 3) and subaqueous .(5) Three remarkable volcanic apparatus in Shengping-Wangjiatun area——layered, micro-shield and cone volcanoes according to volcanic processes and lithofacies distribution.

次火山岩有安山玢岩、流纹斑岩、隐爆角砾岩及自碎角砾岩等；(2)火山岩相——通过岩芯观察、镜下鉴定、测井与地震资料解释，营城组火山岩中发育8种岩相类型，即爆发空落相、溢流相、火山碎屑流、基底涌流相、喷发沉积相、火山泥石流相、侵出相和次火山相等；(3)火山喷发的形式——有爆发、溢流和涌流三种；(4)火山喷发环境——有陆上(如尚深3井火山)和水下两种；(5)火山机构类型——根据火山作用特点和岩相分布特征，在升平—汪家屯地区识别出三类截然不同的火山机构，即层火山、微型盾火山和渣锥火山。

Meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff; in the tufaceous mud, the thermal fluid activity accelerates "maturating" of the organic carbon by heating; and the trace elements show an anomaly in the wall rocks.

同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的"催熟"加热作用，微量元素则出现异常现象。

Contamination of the continental crust material is one of the reasons for andesitic rock formation, but not all.

大陆地壳物质的混染只是安山岩成因中的一部份，并非全部。

The volcanics are most commonly andesitic in composition.

火山岩的组成最通常是安山岩。

The petrophysical properties of volcanic rock reservoirs in Junggar Basin are generally characterized by the following: the acidic lava and auto brecciated lava are the best, especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts.

准噶尔盆地火山岩储层物性一般特点是：酸性熔岩、火山角砾岩最好，特别是经后期构造运动和溶蚀作用改造后的火山角砾岩；安山岩的物性总体优于玄武岩。

The Tertiary andesites are partially mineralized and spatially associated with most of the known mineral deposits in the area.

大专安山岩部分矿化，并在空间上与大多数已知的矿藏，在封锁区内。

Chinese Academy of Sciences , Beijing 100029 , ChinaAbstract : The content s of such platinum-group element s as Ir , Ru , Rh , Pt and Pd in J ianguo basalt s and Wula 2 hada Mg- high andesites were determined using ICP-MS after a nickel sulfide fire assay preconcent ration.

采用镍锍火试金法结合 ICP-MS 分析了碱锅玄武岩和乌拉哈达高镁安山岩样品中的 Ir 、 Ru 、 Rh 、 Pt 和 Pd 的含量。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
