raw clay

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

嘗試了一種從沉積巖中分離提純自生粘土礦物的方法———反復冷凍 -解凍法。

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-新場-合興場地區上三疊統須家河組砂巖為例,應用鑄體薄片、普通薄片、X射線衍射分析和掃描電鏡分析,研究了在成巖過程中自生粘土礦物的沉淀作用及其對儲層的影響。

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.

　提出了一種假說:地球生物信息起源于海陸交界處的一種次生粘土礦物——蒙脫石〔(OH)4Al4Si8O20〕。
