The geophysical exploration in Changdao County is conducted using controlled source audio-frequency magnetotelluric (CSAMT) method. The inversion results reveal obvious evidences of one existed fault ...
Gas data of the Los Azufres geothermal field were analyzed using a method based on equilibrium of the Fischer- Tropsch (FT) reaction: CH4 + 2H2O = 4H2 +CO2 and on the combined pyrite-hematite-magneti...
RIVERSIDE, Calif. — In 2009, a borehole drilled at Krafla, northeast Iceland, as part of the Icelandic Deep Drilling Project (IDDP), unexpectedly penetrated into magma (molten rock) at only 2100 meter...
Chemical and isotopic (D, 18O) compositions of 40 shallow groundwater, 14 observation well water and 2 river water samples in the Sho river fan, Toyama, northern part of central Japan, were analyzed ...
The aim of this study was to understand geochemistry of thermal fluids circulating in the basin at the southwest of Tekman (Erzurum, Turkey) Geothermal Province in Eastern Anatolia as well as to esti...
In order to calculate the chronology of hydrothermal deposits precipitated from hot springs at Mataro, Los Azufres geothermal field, Mexico, their 224Ra, 226Ra, 228Ra and 210Pb activities were meas...
The Aydın-Salavatlı geothermal field is located in the middle part of the Büyük Menderes Graben, and is characterized by normal-fault structures. The stratigraphic sequence of the Aydın...
Clay mineralogical X-ray diffraction and electron microprobe studies have been carried out on separated <2 ?m fractions from cutting and core material from three wells in the Chipilapa geother- mal ...
Abstract: The chemical composition of hydrothermal chlorite was determined by means of more than 200 electron microprobe analyses (EMPA) in almost all of the 70 chlorite-bearing samples taken from 5 b...
Hydrothermal alteration has caused illitization along a 40m vertical profile in the Tsantilis bentonite deposit, Eastern Milos, Greece which consists principally of a Wyoming-type montmorillonite and ...
The crystal chemistry of Fe-Si scales deposited from geothermal brines at Salton Sea, California, was studied by powder X-ray diffraction and spectroscopic techniques including infrared, 57Fe M鰏sbauer...
Mixed-layer clays of variable composition and structure occur in core samples from two drillholes (WK207 and WK210) drilled into the Te Mihi sector of the Wairakei geothermal field. These were identif...
A smectite rich in ferrous iron and low in aluminum occurs abundantly in the Red Sea Geothermal Deposits, and appear to be forming at present.Chemical analyses and Mossbauer spectra indicate the miner...
