Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.

在硅质岩方面：冈底斯构造带侏罗系硅质岩主要属泥质硅质岩，在各个碰撞结合带和弧后盆地中均有产出，主要的产出状态有：①在碰撞结合带中呈岩块产出，构成蛇绿混杂岩的重要组成部分，属蛇绿混杂岩型硅质岩；②在弧后或弧间盆地中呈厚度不等的泥质硅质岩夹层产出，常具"硅灰泥"特征，属弧后深水盆地型硅质岩；③呈夹层状产于弧火山岩系中，属火山热液或火山喷气型硅质岩。

Productivity equation of natural gas well is established.

建立气井产能方程，初步确定火山岩气藏气井产量和无阻流量差异较大，气藏模型类型复杂多样，储层平面分布范围有限，多数压裂井附近存在不流动边界，因此，单井合理配产和控制边底水采出是高效开发徐深气田的重要手段。

On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。
