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.

Varias vetas de roca mineralizadas fueron intruidas en los granitos de Rajastán, India. Algunas de estas vetas de Rajastán presentan una enorme cantidad de metales críticos y raros. Estos metales están asociados espacialmente con las vetas de Degana, Rajastán, India. Para este trabajo se recolectaron seis muestras de la pared y del núcleo de dos vetas. Dos muestras de la pared y una del núcleo de cada veta, respectivamente. Las muestras se seleccionaron para estudios de inclusión fluida y microsonda láser Raman. Se identificaron y clasificaron cuatro tipos distintos de inclusión fluida: el tipo I es una inclusión acuosa bifásica (LH2O+LCO2); el tipo II es una inclusión acuoso-carbónica (LH2O+LCO2); el tipo III es una inclusión carbónica monolíquida (LCO2) a temperatura ambiente; y el tipo IV es una inclusión polifásica (LH2O+VH2O+S). La variación en las temperaturas de homogeneización con diferentes salinidades implica un proceso de fluido mixto. Este proceso fluido se derivó principalmente del granito de la roca huésped. Más tarde, los fluidos magmáticos enfriados se mezclaron con el agua meteórica durante la etapa hidrotermal, lo que puede ser el principal factor clave para la formación de la mineralización de Li-Rb-F-W en Rajastán, India.
