Stacked sills forming a deep melt-mush feeder conduit beneath Axial Seamount

open access: yesGeology, 2020
Magmatic systems are composed of melt accumulations and crystal mush that evolve with melt transport, contributing to igneous processes, volcano dynamics, and eruption triggering. Geophysical studies of active volcanoes have revealed details of shallow-

Application of geological methods for prospecting of podiform chromite deposits in the Khoy ophiolite zone, Northwestern Iran

open access: yesJournal of Economic Geology, 2019
Introduction Podiform chromite deposits are small magmatic chromite bodies formed in the lower section of an ophiolite complex. Podiform chromite mines have produced 57.4 percent of the world’s total chromite production.
