Abstract

The results of prospecting studies of trace elements and activity ratio 234U/238U (АR4/8) in surface waters and groundwaters from the Listvyanka, Buguldeyka, and Olkhon-Priolkhonye polygons of integrated monitoring, organized since 2020, are presented. At the Listvyanka polygon, wide interval of АR4/8 from 1.67 to 2.5 is obtained for groundwater in the Bolshie Koty village, at the Buguldeyka and Olkhon-Priolkhonye polygons that are located in the zone of the Primorsky fault – an interval of AR4/8 from 1.25 to 2.70. These values is general characteristic of large active faults of the central Baikal Rift Zone. Water from the Buguldeyka River differs in terms of both trace element compositions and AR4/8 values from those of its tributary Kurtun due to location of these rivers basins in rocks of the exposed basement of the Siberian Platform and its sedimentary cover, including evaporate carbonate sediments. On the Olkhon island, determined is groundwater that differs in elemental composition from the deep Baikal water.

贝加尔湖Listvyanka、Buguldeyka和Olkhon-Priolkhonye监测多边形的开发:河流和地下水中微量元素和U同位素的找矿研究

介绍了自2020年以来组织的Listvyanka、Buguldeyka和Olkhon-Priolkhonye综合监测多边形地表水和地下水中微量元素和活度比值234U/238U (АR4/8)的找矿研究结果。在Listvyanka多边形上，Bolshie Koty村的地下水得到了从1.67到2.5的宽间隔АR4/8，在位于Primorsky断层带的Buguldeyka和Olkhon-Priolkhonye多边形上- AR4/8从1.25到2.70的间隔。这些值是贝加尔湖裂谷带中部大型活动断层的一般特征。Buguldeyka河的水在微量元素组成和AR4/8值方面与其支流Kurtun的水不同，这是由于这些河流盆地位于西伯利亚地台暴露基底及其沉积盖层的岩石中，包括蒸发碳酸盐岩沉积物。在奥尔洪岛上，地下水的元素组成与贝加尔湖深处的水不同。
