raw clay

A new method with repetitive freezing thawing process was developed to separate authigenic clay minerals from sedimentary rocks.

尝试了一种从沉积岩中分离提纯自生粘土矿物的方法———反复冷冻 -解冻法。

This paper takes upper Triassic Xujiahe formation sandstones in western Sichuan depression as an example to analyze diagenesis of authigenic clay minerals for clastic reservoirs and its effect on reservoirs by means of techniques of core cast slice,ordinary slice,X-diffraction and micro-observation of scanning electric microscope.

本文以川西坳陷孝泉-新场-合兴场地区上三叠统须家河组砂岩为例,应用铸体薄片、普通薄片、X射线衍射分析和扫描电镜分析,研究了在成岩过程中自生粘土矿物的沉淀作用及其对储层的影响。

A hypothesis was described in the paper as follows; biological information on the earth originated from the montmorillonite〔(OH)\-4Al\-4Si\-8O\-\{20\}〕 that was a kind of secondary clay mineral on the juncture of the sea and the land.

　提出了一种假说:地球生物信息起源于海陆交界处的一种次生粘土矿物——蒙脱石〔(OH)4Al4Si8O20〕。
