WebChemical analyses must be determined to be reliable before they are used to calculate geothermometers. The USGS Geothermal Resource Assessment will rely on the silica geothermometer developed by Giggenbach that approximates the transition between chalcedony at 20??C and quartz at 200??C. Above 200??C, the assessment will rely on … WebKey Words--Chlorite Geothermometer, X-Ray Diffraction. INTRODUCTION Chlorite minerals are a principal component of a great variety of rocks, including sedimentary, tow- grade metamorphic and hydrothermally altered rocks. By virtue of the wide variability in its composition, chlorite can act as a record of the chemical and phys- ...

Ferry and Spear's calculation of the garnet-biotite geothermometer (1978), involved running experimental reactions between biotite and garnet at a constant pressure (0.207 GPa) and varying temperatures between 500°C and 800°C. The focus of the reactions was on the Fe-Mg exchange: Ferry and Spear (1978) used a garnet solid solution of almandine and pyrope (All90Prp10) with an iron mole fraction of XFe = 0.9 for all reactions.
