By summarizing the futures of the relative permeability curve in low permeable reservoirs and study of the futures of relative permeability curve in lithic arenite which rock fragments are most come from tuff and lava, it is the reservoirs rock character, the type of detrital minerals, the degree of grains coarse and the lay out of clay mineral that are main influencing factors which influence the relative permeability curve.

本文在总结低渗透油藏油水相对渗透率曲线特征的基础上，对以火山岩、凝灰岩岩屑为主的岩屑砂岩相对渗透率曲线特征进行研究，并分析了其影响因素，研究表明低渗透储层的岩石学特征，碎屑颗粒的成份、结构，其表面的粗糙程度，及其粘土矿物的产状对相对渗透率曲线有明显的影响。

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。

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian～early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末～白垩纪初印度大陆的北缘同时期存在大陆向上挠曲，导致陆源碎屑输入量的快速增加，石英砂岩广泛存在；早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深，使得较深部的深成火山岩暴露并遭受侵蚀；石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&，说明构造运动首先是从特提斯喜马拉雅的东部开始（大印度与澳大利亚的彻底分离），然后逐渐波及西部的，东西时间差为15～20Ma；由于地壳均衡作用，大陆分离后原先地壳挠曲转变为地壳下沉，发生强烈的构造沉降，故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。

Reefoid carbonate and siliciclasstic mixed sediments can be identified through components, in which both coral debris and terrigenous elastics account for 10%~50% respectively and other biogenic fragments are not counted.

礁源与陆源混合沉积的鉴别标志是珊瑚骨屑和岩屑各占10%~50%，其他生物碎屑不计。

As the years pass and layer on layer of rock fragments pile up, they are squeezed or compacted by the weight of the materials on top of them. Then sediments may be cemented together, forming the sedimentary rocks.

随着时间的流逝，岩石和矿物碎屑一层层地堆积起来，上覆岩屑物质的重量对下伏岩屑产生压实作用，然后沉积物被胶结在一起，最终形成沉积岩。
