The discovery of diamonds in metamorphic rocks of continental affinities occurred shortly
after the discovery of coesite in similar rocks. These important discoveries led to a revolution …

This review systematically presents all finds of geogenic, impact-induced, and
extraterrestrial iron silicide minerals known at the end of 2021. The respective morphological …

Recently a number of reports claimed enigmatic appearance of high-pressure and super-
reduced minerals in ophiolitic chromitite and peridotite. Diamond, moissanite, various metal …

Several recent papers have purported to find ultra-reduced minerals—as natural examples—
within ophiolitic mantle sections, including SiC moissanite, Fe-Si alloys, various metal …

The enigmatic appearance of cuboctahedral diamonds in ophiolitic and arc volcanic rocks
with morphology and infrared characteristics similar to synthetic diamonds that were grown …

The origin of the assemblage of ultra-high pressure (UHP), super-reduced (SuR) and
several crustally derived phases in ophiolitic chromitites is still hotly debated. In this paper …

Abstract The Pozanti–Karsanti ophiolite (PKO) is one of the largest oceanic remnants in the
Tauride belt, Turkey. Micro-diamonds were recovered from the podiform chromitites, and …

Geophysical investigations and laboratory experiments provide strong evidence for
subduction of ancient oceanic crust, and geological and mineralogical observations suggest …

Part VIII of the evolutionary system of mineralogy focuses on 1220 metamorphic mineral
species, which correspond to 755 root mineral kinds associated with varied metamorphic …

Fulgurites are glassy structures formed when lightning strikes the ground, causing ground
material (eg, rocks, sediments, or soil) to melt and fuse. While fulgurites are relatively rare …
