study of khraghan (ghazvin) mineral springs
one of the natural resources in our country is mineral water that hasnot been used as it should, and can be found allover the country. kharaqhan hot water is located by the ghazvin-hamedan road. this spring is being used in a very primitive way and is the subject of this investigation. the analyses were carried on the field and in the laboratory by standard methods and the results are shown in ...
متن کاملRadiological aspects of some Egyptian thermo-mineral springs.
In Egypt, nineteen water springs with temperatures exceeding 35 degrees C, which can be considered thermal waters, were reported. The radiological aspects of thermal water in three northern regions of Egypt (Gulf of Suez, Cairo, and Bahariya Oasis) were investigated. The activity concentrations of natural radionuclides of 226Ra, 40K, total uranium and 210Pb (210Po) in water samples were determi...
متن کاملIn situ production of crenarchaeol in two california hot springs.
Crenarchaeol, a membrane-spanning glycerol dialkyl glycerol tetraether (GDGT) containing a cyclohexane moiety in addition to four cyclopentane moieties, was originally hypothesized to be synthesized exclusively by the mesophilic Crenarchaeota. Recent studies reporting the occurrence of crenarchaeol in hot springs and as a membrane constituent of the recently isolated thermophilic crenarchaeote ...
متن کاملBarioperovskite, BaTiO3, a new mineral from the Benitoite Mine, California
Barioperovskite, ideally BaTiO3, is a new member of the perovskite group. It is found as microto nano-crystals in a host of amorphous material contained within hollow, tubular inclusions in benitoite from the Benitoite Mine, San Benito County, California, U.S.A. The mean chemical composition determined by electron-microprobe analysis is (wt%) BaO 65.46, TiO2 34.57, SiO2 0.89, sum 100.92. The em...
متن کاملHydrogeochemistry and Genesis Analysis of Thermal and Mineral Springs in Arxan, Northeastern China
In this work, the hydrogeochemistry and environmental isotopic compositions of thermal and mineral springs in Arxan, northeastern China, were used to assess the genesis of the thermal system hosted by deep-seated faults. The reservoir temperature was calculated using the mineral saturation index and geothermometers. According to isotopic analysis, the spring water was of meteoric origin. Sixtee...
