The regularities of distribution of methane and sulfide sulfur (total sulfide ? ?H2S) in the bottom sediment deposits of therapeutic sulfide mud Lake Bolshoy (Big) Tambukan, located in the region of Caucasian Mineral Waters. Determination of methane and sulfide sulfur were produced in black and dark grey therapeutic mud, as well as in the underlying steel-grey clays and coastal sediments, represented by yellow-brown clay and loam. The formation of therapeutic sulfide mud flows through the biogeochemical environmen...

The results of Chembursky lake, Vityazevsky, Kiziltashsky and Bugazsky coastal salt lakes expeditionary research are observed, aimed to examine the allocation of methane and sulfur sulfide (total sulfide) according to the vertical cut of bottom sediments (sulfidic muds), and also the value of Eh and pH. pH and Eh values in the examined horizons of coastal salt lakes bottom sediments vary correspondingly in the limits from 7.33?8.06 and -198?-2.5 mV, in the Chembursky lake sediments ? 7.47?7.64 ? -78?+46 mV. CH4 an...
