Abstract A radiological analysis of hot spring water of Hammam Debagh (also called Hammam Meskhoutine) and its associated deposits was realized. Hammam Debagh is considered to be the second hottest springs in the world with a temperature of 98°C and this lead to the creation of travertine. This later was formed because of limestone deposited by mineral springs in a rapid sedimentation of calcium, magnesium bicarbonates, and sulphides. The analysis showed that two-thirds of radioactivity was left by spring water in their deposits. The presence of uranium in the spring deposits was due to the property of the uranyl ion to form stable complexes with carbonates and precipitates. The radiation hazards indexes were estimated and compared with those given in literature.

Copper Sulphides

This work presents the results of sulphur isotopic analyses conducted on 130 samples of sulphides and 50 samples of sulphates, collected in different parts of the Lubin mine. Simple copper sulphides contain isotopically very light sulphur. For digenite average value of δ34S was found to be –35,9‰, and for chalcocite –32,0‰. Bornite also has low value of δ34S, on average –31,7‰. Slightly higher values were found for chalcopyrite and covellite: –29,6 and –27,9‰ on average. The heaviest sulphur is in tennantite–tetrahedrite series: –9,3‰. Sphalerite and galena also have isotopically light sulphur, –27,1 and –25,4‰, respectively. The lightest isotopic composition of sulphur was found in pyrite and marcasite (–37,9‰). There were found consistent differences in the isotopic composition of sulphides depending on their formation and localization in the deposit. Barite from the Lubin mine is shows higher values of δ34S: 12,3‰ on average, similarly to gypsum and anhydrite: 12,1‰. All those minerals have lighter composition when they occur in veins with sulphides comparing those in barren veins. Weathering sulphates – chalcantite and epsomite have the lowest values of δ34S, similar to the composition of copper sulphides.

Sulphur Isotopic Composition

Sulphur-isotopic composition of soft tissues from Bathymodiolusmarisindicus collected from hydrothermal vents in the Indian Ocean was reported. The δ34S values of the soft tissues (+3∼+5‰ vs Cañyon Diablo troilite) were nearly identical to those from the associated hydrothermal fluid and chimney sulphides (+5 to +8‰), but were significantly different from that of the common seawater sulphate (+21‰), which suggested that the endosymbiotic bacteria used sulphide in the fluid as an energy source. Transmission electron microscopic observation of the endosymbionts also suggested that the symbiont is a thioautotroph. Bathymodiolus species, which depend on either sulphide or methane oxidation, or both, have a worldwide distribution. Bathymodiolus marisindicus from the Indian Ocean has a close relationship with congeners in the Pacific Ocean as evidenced by form of symbiosis. Biogeography and migration of the genus Bathymodiolus based on the relevant data are briefly discussed.
