“…The Bundelkhand granite hosts geothermal circulation at Tattapani (Minissale et al 2000) and the reported heat generating capacity of these granites varies from 3-8 lW/m 3 . These are fertile granites with high thorium (3-101 ppm), uranium (5-14 ppm) and potassium contents, indicating that they are high heat generating granites (Chandrasekharam and Chandrasekhar 2010).…”

Creation of optimal fracture networks through enhanced geothermal system within the reservoir for the extraction of the geothermal energy will require proper understanding of the thermo-mechanical behavior of the reservoir rocks i.e. granites. Current research work has focused the thermo-mechanical properties of granite under various temperature and strain rate conditions. Bundelkhand granite of India has been investigated for the proposed research work. Four different strain rates viz. 0.05, 0.5, 5.0 and 50.0 mm/ min at three different temperatures viz. room temperature (25°C), 200 and 400°C were considered for experimental analysis. It was observed that at room temperature, with increasing strain rate the uniaxial compressive strength of the rock increases and the same trend is also observed at higher temperature conditions. However, at low strain rate (0.05 mm/min) the compressive strength decreases with increase in temperature and the trend is irregular at higher strain rates. It was also observed that Young's modulus of Bundelkhand granite increases with increase in strain rate however it reduces with increase in temperature. Thermal conductivity value of Bundelkhand granite ranges from 3.1 to 3.6 W/m K.

“…Icelandic lava flows, which exhibit a relatively unaltered basaltic composition, have served as geological, geomorphological, and geochemical Mars analogues for decades (Allen et al, 1981;Nelson et al, 2005;Cousins et al, 2010;. Minissale et al (2000) measured the fluid composition of the moderately hydrothermal (48°C) Deccan flood basalt springs, sourced from up to 3 km depth. This system has been used as a baseline for geochemical models of Gale Crater, the landing site for the Mars Science Laboratory mission (Schwenzer et al, 2012) and is the basis for Fluid 6 used in this study.…”

The Potential for Biologically Catalyzed Anaerobic Methane Oxidation on Ancient Mars

et al. 2014

This study examines the potential for the biologically mediated anaerobic oxidation of methane (AOM) coupled to sulfate reduction on ancient Mars. Seven distinct fluids representative of putative martian groundwater were used to calculate Gibbs energy values in the presence of dissolved methane under a range of atmospheric CO 2 partial pressures. In all scenarios, AOM is exergonic, ranging from -31 to -135 kJ/mol CH 4 . A reaction transport model was constructed to examine how environmentally relevant parameters such as advection velocity, reactant concentrations, and biomass production rate affect the spatial and temporal dependences of AOM reaction rates. Two geologically supported models for ancient martian AOM are presented: a sulfate-rich groundwater with methane produced from serpentinization by-products, and acid-sulfate fluids with methane from basalt alteration. The simulations presented in this study indicate that AOM could have been a feasible metabolism on ancient Mars, and fossil or isotopic evidence of this metabolic pathway may persist beneath the surface and in surface exposures of eroded ancient terrains.

“…Further, the Narmada and Tapti Rivers flow through areas more prone to inputs from groundwater and hydrothermal waters. A number of hydrothermal springs have been reported along the Narmada-Tapti lineament (Minissale et al, 2000). Ramesh and Subramanian (1988) also had reported major ion composition of the Krishna River and in a few of its major tributaries as a part of their work to determine fluxes of various elements transported by this river system to the Bay of Bengal.…”
