Geology transition zone

The brittle-ductile transition zone (hereafter the "transition zone") is the zone of the Earth's crust that marks the transition from the upper, more brittle crust to the lower, more ductile crust. For quartz and feldspar-rich rocks in continental crust, the transition zone occurs at an approximate depth of 20 km, at temperatures of 250–400 °C. At this depth, rock becomes less likely to fracture, and more likel… WebJan 31, 2024 · Scientists identify geological 'Goldilocks zone' for the formation of metal ore deposits New research could lead to the targeted mining of metals that will be essential …
