碎屑的

Plentiful oil and gas reservoir in the Tertiary clastic rocks in north edge of Chaidamu Basin.

柴达木盆地北缘第三系有丰富的油气储集，主要存在于碎屑岩中，油气的储集明显与碎屑岩的沉积环境和成岩作用有关。

Basal synthem is the Taishan mountain group in archaean, is mainly the gneiss; The paleozoic synthem besides the regional lost stratas: Upper Ordovician, Silurian-Devonian and Lower Carboniferous, other stratas have the distribution, divides into Cambro-ordovician and Permo-Carboniferous two structure subgroups. Cambro-ordovician is a set of carbonate construction, Permo-Carboniferous system is a set contains the coal clastic rock deposition; In the mesozoic synthem lost Upper Triassic and Upper Crataceous ,growth Middle-Lower Triassic and Middle-Lower Jurassic and Lower Crataceous three structure subgroups, main growth varicolored land facies clastic rock, discovered rich fossil data such as cryptogam ,Ostracoda and Chareae and so on.

基底构造层指太古界泰山群，主要为片麻岩；古生界构造层除区域性缺失的上奥陶统、志留-泥盆系和下石炭统外，其余地层均有分布，分为冷武-奥陶系和石炭-二叠系两个构造亚层，冷武-奥陶系为一套碳酸盐建造，石炭-二叠系为一套含煤碎屑岩沉积；中生界构造层缺失上三叠统和上白垩统，发育下-中三叠统、下-中侏罗统和上侏罗-下白垩统三个构造亚层，为杂色陆相碎屑岩，发现丰富的孢粉、介形类、轮藻等化石；新生界古近系岩性以砂泥岩互层为主，含薄层油页岩，新近系-第四系为一套河流相沉积。

Despite of this, the field geology and the character of pyroclastic rocks remain the basis of the petrogenesis of pyroclasic rocks.

尽管这样，野外地质和火山碎屑岩的岩性特征，仍是火山碎屑岩成因研究的基础。

In this sea area, the main origin of the detrital minerals is Hainan island, and the characteristics of genetic mineralogy of the zicon and garnet indicate that the detrital minerals mainly come from regional mid-degree-metamorphic area.

3研究区碎屑矿物主要物源是海南岛，锆石和石榴石的成因矿物学特征指示研究区的碎屑矿物可能主要来自中级区域变质物源区。

The main lithologic characteristic is that the rock types are dominated by light-colored clastic rocks reflecting the oxidation environment with a low maturity. The grain size distribution and sedimentary structure show that the rocks have the sedimentary characters of both gravity currents and tractional currents. Plant fragments are lacking and bioturbation structures are abundant and cyclic. Sandbodies are distributed in a ring shape.

其主要岩性特征为：岩石类型以反映氧化环境的浅色碎屑岩类为主，成熟度较低，粒度分布和沉积构造反映其兼有重力流和牵引流的沉积特点，植物碎屑贫乏而生物扰动构造丰富且具周期性，砂体呈环带状分布。

There are 4 end members of volcanic clasts, including catapult airfall, ejection airfall, base surge and volcanic clasts flow.

与火山作用有关岩相有4种端元的火山碎屑岩相：弹射坠落爆发空落相、喷射降落爆发空落相、热碎屑流相和热基浪相。

If the volcanic clasts were deposited on volcanic slope and/or fluvial plain, they would occur in the 4 faceis mentioned above or in alluvial fan and braid stream.

与火山作用有关岩相有4种端元的火山碎屑岩相：弹射坠落爆发空落相、喷射降落爆发空落相、热碎屑流相和热基浪相。

Combined with previous studies, we suggest that the 1100-2200 Ma zircons perhaps originate from the China North Craton, while the zircons of 520 Ma may stem from Jiamusi massif.

根据目前有关年代学研究成果，推断1100~2200 Ma碎屑锆石可能来源于华北克拉通，而样品中的520 Ma的碎屑锆石则可能来源于佳木斯地块。

This paper expatiates on the hazards of volcanic falling tephra, and demonstrates the pratical importance of making program for forecasting the risk of volcanic falling tephra.

简述了火山空降碎屑灾害的危害性，指出研制火山空降碎屑灾害预测软件包的实际意义。

The optimal volumetric concentration of the acid is determined by comparison of the effects of one acid with different volumetric concentrations on the solution ration of the fragmental rock;then with analysis of the experimental results of the fragmental rock's breaking rat.

比较不同体积分数单种酸对碎屑岩心溶蚀率，优化最佳酸液体积分数值；在此基础上，研究不同体积分数酸液复配体系对碎屑岩心破碎率实验结果，优选出适合萨零组油层的酸化解堵配方为7%HCl+0.5%HF+5%CH3COOH及12%HCl+0.5%HF+0.5%HBF4+3%CH3COOH体积分数

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
