Some Thoughts on Making the Oldest Continental Crust Using Petrological Experiments - Don't Shoot the Messenger!
Abstract: Ongoing work to investigate the formation of the oldest continental crust 4.3-3.5 billion years ago using experimental petrology. The first continental material is represented by granitoids belonging to the tonalite, trondhjemite, granodiorite suite (TTG). The TTG are thought to be derived from the partial melting of metamorphosed basis igneous rocks. In this seminar we look at the products of melting experiments on several modern and ancient starting compositions and explore whether they can generate TTG-like liquids.
