Abstract: Abstract. Seismic faulting causes wall rock damage, which is driven by both mechanical and thermal stress. In the lower crust, co-seismic damage increases wall rock permeability, permits fluid infiltration and triggers metamorphic reactions that transform… read more here.

DOI: 10.5382/econgeo.5142
Abstract: A feature of some of the most important lithium deposits that has received limited attention is the alteration of hornblende in the amphibolite host to holmquistite. This study investigates the holmquistite-bearing alteration halo of amphibolite… read more here.
