Abstract:
Based on the simulating experiments on the formation mechanism of banded iron-silica formation in the solution from weathering-leaching basalts, the authors have come to the conclusion that Archaean seawater was an acid solution evolving from strong ...

Abstract:
Pb-210 atmospheric flux of 2.06dpm/cm2·year has been determined by means ofmeasuring the soil sample from the area near the East China Sea continental shelf.The result agrees with the value prodicted from the model. After the Pb-210 activities in the...

Abstract:
Ancient resedimented carbonates along platform-foreslope are considered as a deep-water type of carbonates, including gravity flows, gravity slide ( slump ) deposits, and talus wedges ( aprons ) . A series of deposits belonging to this kind of carbon...

Abstract:
The Upper Devonian in Guilin district consists of a series of carbonate strata of marine facies. Obviously, they are of the same period and different facies. They can be divided into two lithofacies. One is dolomitic limestone facies, its lower part ...

Abstract:
The marine turbidite deposit rock of Middle Triassic is widely distributed in Napanjiang River of the Yunnan-Guizhou-Guangxi boundary and the Youjiang River region of western Guangxi. It is abundant, dark-gray coloured, medium-or-thin-bed, cyclotheri...

Abstract:
It is clear that different clay minerals are usually of different grain size. In order to study their interrelationship, six grades of grain size were seperated in this paper ( i. e. 0.5μ, 1μ, 2μ, 4 μ, 8μ, and 20μ) , their mineral composition and geo...

Abstract:
This paper mainly deals with how to determine paleosalinity by means of δ13C. In addition, the determination of paleotemperature is also dealt with by the use of δ12O. By a thorough analysis of the systematic data,the author has reached the following...

Abstract:
In china, hydrogen sulphide contents of natural gas are obviously controlled by reservoir lithology. H2S contents of natural gas in clastic rocks are very low even down to zero. The highest H2S contents of natural gas in those rocks are 0.68%, which ...
