- Abstract
The communication reports characterization of fluid involved in the process of serpentinization of the ultramafic rocks from the Rakhabdev-Kherwara sector constrained along the Rakhabdev Lineament, in southern Rajasthan, northwest India, at a temperature of around 350°C. The relatively low water/rock ratio in the rocks suggests the possibility of extensive isotopic exchange over a long period of time in a completely fluid buffered system. The isotopic data suggest possible involvement of at least two different fluid systems, either involving highly evolved meteoric water or a mixture of hydrothermal fluids with the meteoric water. The presence of extensive chloritization in the metamorphic country rocks suggests involvement of low degree of metamorphism during the alteration. Additional isotopic studies are required to understand the role of different fluid sources in altering the ultramafic rocks of the studied region.
