| Abstract | Liquid rich secondary fluid inclusions in barite and calcite from drill hole PLTG-1 in the Platanares geothermal area, Honduras, have homogenization temperature (The) that range as much as several tens of degrees Celsius higher than the warmest reported temperature for the drill hole. Many of the barite Th measurements plot above the reference surface boiling point curve, however, absence of evidence for boiling in the fluid inclusions indicates at the time the minerals formed, the ground surface must have been several tens of meters higher than at present and underwent stream erosion to the present elevation. Melting point temperature (Tm) values of drill hole PLTG-1 fluid inclusions suggest that much of the barite and calcite precipitated from fluids of significantly greater salinity than present Platanares hot spring water. |
