Ghost granophyre: A new texture with implications for plagiogranite differentiation and Ti-in-Quartz thermometry
… origin of plagiogranites is poorly understood. Granophyre, which is also poorly understood, is a common texture in plagiogranites as well as other granitoids. I present observations of “Ghost Granophyre,” a new cathodoluminescence texture of granophyre in Troodos quartz crystals which I argue …
