Evidencia de un proceso fluido en rocas veteadas ricas en Li-Rb-F-W de Degana, Rajastán, India

Several mineralized vein rocks were intruded into the granites of Rajasthan, India. In some of the vein rocks in Rajasthan has associated with enormous amount of critical metals and rare metals. The metals are spatially associated with the vein rocks of Degana, Rajasthan, India. Six samples were collected in wall and core of the vein rocks. Two samples from wall and one sample from core of each vein respectively. The samples were selected for fluid inclusion and laser Raman microprobe studies. Four distinct types of fluid inclusion were identified and classified. Type I is aqueous bi-phase (LH2O+LCO2) inclusion; Type II is aqueous-carbonic (LH2O+LCO2) inclusion; Type III is carbonic mono liquid (LCO2) inclusion under room temperature; Type IV is polyphase inclusion (LH2O+VH2O+S). The varying homogenization temperatures with different salinities implies mixed fluid process. The fluid process was mainly derived from the host rock granite. Later the cooled magmatic fluids were mixed with the meteoric water during hydrothermal stage may be the major key factor for formation of Li-Rb-F-W mineralization in Rajasthan, India.
