The northwestern region of Bangladesh, an extension of India's ancient landmass, differs geologically from the sediment-covered rest of the country. Our research using gravity, magnetic, seismic, and drilling methods revealed distinctive magnetic anomalies suggesting gabbro rocks along fault lines, forming patterns of elevated and depressed blocks underground. This structural model, particularly in the Rangpur Saddle area, indicates significant potential for mineral resources.

Contrary to current CCS (Carbon Capture and Storage) models, reaction experiments conducted at subsurface stress and temperature conditions reveal that feldspars, common, reactive grains in sandstone reservoirs, can undergo significant chemical and mechanical changes when exposed to CO₂ enriched water. These chemo-mechanical processes, including grain fracturing, dissolution, and clay precipitation, can modify fluid pathways and rock strength, potentially reducing reservoir productivity and increasing leakage risk.

Curling stones often collide with each other during a game. Over time, these collisions cause damage in the striking bands on the sides of the stones. We determined experimentally how hard these stones collide into one another. We then looked at old curling stones to understand how damage builds up in these rocks. We found that early, fast impacts produce fractures until the striking band is saturated in fractures. Repeated impacts after this stage make fractures grow.
