The first data on abnormally high δ13С values in hydrocarbonates (НСО 3-) dissolved in underground waters of coal deposits of Kuzbass (up to +30.9‰) are reported. It is shown that such an unusual isotope composition of waters results from the long, strictly directed interaction in the water–rock–gas–organic material system occurring under the conditions of hindered water exchange. Extensive fractionation of C isotopes is the result of the evolution of the water–rock–gas–coal system after penetration of infiltration waters into the coal deposits and their long interaction with all these components, rather than metamorphism of organic material upon its transformation into coal. With respect to such an approach, the isotope composition of dissolved C may indicate the duration of the evolution in the water–rock–gas–organic material system. 相似文献

One of the probable mechanisms that controls the composition of highly mineralized chloride groundwaters is studied using physicochemical numerical simulations of equilibria in water–rock systems. Concentrated brines in the Olenek cryoartesian basin in the northeastern Siberian Platform are determined to be undersaturated with respect of major rock-forming minerals, which suggests that the metamorphosed sedimentary brines should have been diluted by meteoric waters during a certain evolutionary episode of the permafrost zone of the basin in the Late Pleistocene and Holocene. 相似文献

The chemical, gas, and isotopic compositions of nitric thermal waters in the Baikal Rift Zone are considered. It is shown that the behavior of sulfate and carbonate ions in hydrothermal systems is different, which indicates that they are of two different origins. The studied thermal waters are of five chemical types formed in different geologic conditions. Special attention is given to the genesis of hydrotherms, the geologic and geomorphologic conditions of their recharge, and their equilibrium with rocks. It has been established that most of chemical elements of the waters migrated from rocks, but a significant portion of them is bound by secondary minerals, which results in their deep differentiation, accumulation, or precipitation. Thus, the so-called redundant elements appear, which were earlier considered to be of mantle origin. 相似文献

This paper addresses the main mechanisms controlling the continuous and geologically long evolution of the water-rock system, which produced diverse hydrogenous mineral complexes. The concept of such complexes was introduced by the author. It was shown that the water-rock system is a steady-state and equilibrium-disequilibrium one. Its development occurs in a far from equilibrium region and results in the formation of fundamentally new mineral associations and geochemical types of water. Taking into account that water is the main factor controlling the evolutionary trend of this system, it is argued that this system must be among the most important targets of hydrogeology. 相似文献

Geochemistry of sodic waters in the Datong intermountain basin,Shanxi Province,northwestern China 总被引：1，自引：0，他引：1
The paper presents a critical analysis of current concepts of the origin of sodic waters. The example of the Datong Basin
with widespread sodic waters is employed to demonstrate that these waters typically have salinities of 0.6–4.5 g/l at pH of
7.8–8.8. It was determined that sodic waters are in equilibrium with calcite and clay minerals (montmorillonite and kaolinite)
and, sometimes, also with analcime but are never in equilibrium with anorthite, albite, forsterite, microcline, and muscovite;
i.e., the water-rock system is in equilibrium-unequilibrium state. The degree of evaporation concentration of salts is in
places as high as a few tens. The complex analyses of conditions under which sodic waters are formed indicates that these
waters are produced during a certain weathering stage of aluminosilicates, after the groundwaters have reached equilibrium
with calcite. The time when this equilibrium can be reached is controlled by the intensity of the water exchange.
