Frictional Stability of Laumontite Under Hydrothermal Conditions and Implications for Injection‐Induced Seismicity in the Gonghe Geothermal Reservoir, Northwest China

Geophysical Research Letters, Volume 51, Issue 10, 28 May 2024.
Abstract Laumontite is a common and potentially frictionally unstable hydrothermal alteration product present in deep faults of the Gonghe EGS reservoir. We characterize the friction‐stability characteristics of synthetic laumontite gouge under in situ reservoir conditions. The pure laumontite gouge is frictionally strong (μ = 0.73–0.98) and the quartz/

Magnetotelluric images of the medium enthalpy Bakreswar geothermal province within a granitic gneissic complex, Eastern Indian Peninsula

Geophysical Prospecting, Volume 72, Issue 2, Page 857-881, February 2024.
Abstract The Bakreswar geothermal province represents a medium enthalpy geothermal system with its Bakreswar and Tantloie hot springs. It lies within the Chotanagpur Granite Gneissic Complex in the eastern part of the Indian Peninsula. The province has a high heat flow and a high geothermal gradient of 90°C/km.

Magnetic Fabric of Freshly Consolidated Lacustrine Mudstones Constrains the “Present‐Day” Strain Field

Geophysical Research Letters, Volume 51, Issue 2, 28 January 2024.
Abstract The anisotropy of magnetic susceptibility (AMS) has great potential in deciphering weakly deformed fabrics that may be related to tectonic stress. Previous studies have suggested that magnetic lineation is a good indicator of paleostrain direction.

Experimental Study on the Evolution of Fracture Aperture of Single‐Fracture Granite during Liquid Nitrogen Cold Shock Cycling

Geofluids, Volume 2024, Issue 1, 2024.
Fractures in hot dry rock (HDR) reservoirs are the locations where heating fluid flows exchange heat with the HDR matrix. Cold shock with liquid nitrogen is one method for stimulating cracks. This study investigates the evolution law of fracture aperture under cold shock with liquid nitrogen.
