Nov 29, 2006 · Thin bands of katophorite and less silicic amphiboles occur (1) around winchite/barroisite composite grains (Fig. 4), (2) at the interface between garnet and barroisite and (3) in veins (Fig. 5). These amphiboles are distinctly richer in Ca-tschermakite and edenite components than winchite/barroisite formed at the earlier stage of exhumation

May 23, 2020 · Three types of amphibolites were found around a large serpentinite body in the basement of the Ohmachi Seamount in the Izu-Bonin-Mariana arc: epidote-albite amphibolite, epidote-garnet amphibolite, and garnet-zoisite amphibolite. The epidote-albite amphibolite shows a mid-ocean ridge basalt geochemical affinity based on whole-rock chemistry and Nd and Sr isotopes. The epidote

This carbonatite contains the amphibole minerals winchite and barroisite. Ferrocolumbite forms subhedral to anhedral, sometimes strongly poikilitic, individual grains and composite grains with pyrochlore. Mineral liberation analyses show that the majority (~80%) of liberated grains are less than 110 µm in diameter
