     On the basis of the division into third-order sequences in different paleogeographic settings and their tracing and correlation in space,12 third-order sequences may be distinguished in the Carboniferous and Permian strata in the basin and its adjacent areas.

It is the first time that glauconite has been found in permian strata in Guizhou province. Based upon the identification of microscopic characteristic of glauconite and the measurement of mineral physics(such as X-ray diffraction analysis,infrared obsorption spectra analysis as well as microprole,scanning-electron microscope). In this paper the author deal with determination in more detail to glauconite mineralogy and makes a preliminary approach to its formation and genetic mechanism. the following conclusions...

The liquid inclusions predominate in rocks.And they symbolized a good, bad, and middle petroleum exploration prospect...

The type, character, temperature and existing form of fluid inclusion in car bonatite are described in this paper.Based on the relationship between fluid inclusion and petroleum exploration, three situations can be classified as follows. l. A great amount liquid and pure liquid inclusions present and the pure gas inclusions can not be seen in rocks; 2. Only the gas and pure gas inclusions occur: 3. The liquid inclusions predominate in rocks.And they symbolized a good, bad, and middle petroleum exploration prospect in Guizhou respectively. According to the temperature of fluid [inclusion, there are three situations about inclusions, 1. Temperature of inclusions is lower than 140C or 170C, which present in post Ordovician strata in the east part of Guizhou; 2.Temperature 200C, in permian strata in North and South Guizhou; 3. Temperature 140C-150C, in Permian strata of Middle Guizhou. They also reflect the good, bad and middle petroleum prospect in Guizhou correspondingly. The ratio, CH4/(CO2+H2O ) =0.015-0.03, in the gas phase of fluid inclusion from Wenan Sinian System, is higer than that from some well-known oil and gas formation and therefore the petroleum can not be found in Sinian strata of this area. This result will be of significance for other area.

本文对贵州碳酸盐岩中矿物流体包裹体的类型、特征、温度、成份与石油地质条件的关系进行了综合分析和归纳,并用矿物流体包裹体来划分油气勘探远景,对油气资源评价提供了重要的科学依据。

Nine abnormal spots of reflecting seismic information have been revealed in Lower Permian strata from Neijang to Hechuan in Central Sichuan in the light of the concept of Emei Taphrogenesis. They are distributed in rows in four NE-trending anticlinal zones and could be the reflection of grouped reefs, or lithologic change on the rim of platform block, or even some small faults. They probably suggest some new field for gas exploration and worth further prospecting.
