By using geological and geochemical data, the genetic type of the Silurian asphaltic sandstones in Tarim Basin is investigated and divided as the following:(1)Oxidized asphalt on surface or in shallow-layer is the heavy asphalt crude and solid oxidized asphalt or gilsonite formed by volatilization, oxidization, water washing and biodegradation in oil-layer outcrop area or near earth surface.

通过对地质、地球化学等资料的研究，认为塔里木盆地志留系沥青砂岩有5种成因类型：①表生—浅层氧化沥青是指在油层露头区或油层位于近地表处，由于挥发、氧化、水洗和生物降解等作用而形成的一些焦油状沥青质重油以及固体浅层氧化沥青或硬质沥青。

The research based on mineral analyses and experiments show that in the sulphate system hydronic jarosite will precipitate when the concentratjon of Fe3+ and SO increases, and goethite will be formed by hydrolises, or goethite and hydrogoethite will be formed when the concentration of .

运用多种方法鉴定表明，在硫酸盐体系中，从高浓度Fe3+和SO溶液中形成的草黄铁矾在表生条件下可水解成外铁矿。

Regarding groundwater as the main clue, the study of assessment method of supergene eco-environment in watersheds is developing.

以地下水为主线，开展流域表生生态环境评价的方法研究尚处于发展之中。

In addition, Cd and Tl are the potential toxic elements in the supergene environment; therefore, their isotopic composition could be used to trace the source of contamination.

另外，Cd，Tl是环境污染的主要潜在元素，因此采用稳定同位素示踪还可能示踪表生环境中的污染来源。

In the course of alteration,the unstable elements in supergene zone are leached out in quantity,but the stable ones are relatively enriched.

在蚀变过程中，那些在表生条件下不稳定或较不稳定的元素大量流失，而那些稳定或较稳定元素则很少流失或相对富集。

Due to the surface ecological environment is controlled by the water table, so to protect the water table from obvious decline is a core task for the water-conserving mining in the fragile ecological mine area.

表生生态环境严格受控于地下水位，采煤过程中，控制地下水位不发生明显下降是陕北生态脆弱矿区保水开采的核心。

There are three evolution paths for the kaolinitic rocks in the diagenesis:one is that kaolinite is transformed to the mixed minerial of kaolinite/dickite and dickite in the acid environment; the second is to be trnasformed to the ammonium illite,chlorite and pyrophyllite in alkaline environment;The third is to be transformed to well ordered kaolinite in the superfacial environment. The highly orderization of kaolinite may be related to the hot solution underground.

提出煤系高岭岩三种成岩演化轨迹；一种是在酸性环境下朝高岭石/地开石间层矿物和地开石方面演化；另一种是在碱性环境中朝氨伊利石、绿泥石和叶腊石方向演化；第三种是在表生环境种朝高度有序高岭石方向演化，高岭石的高度有序化可能与热水溶液作用有关。
