Ghost granophyre: A new texture with implications for plagiogranite differentiation and Ti-in-Quartz thermometry
Understanding the origins of the Earth and its crust is a fundamental goal of the geosciences and the construction of the oceanic crust comprises half the story of our planet’s unique bimodal crustal distribution. The oceanic crust is overwhelmingly mafic with the exception of plagiogranites, which …
