No evidence of supracrustal recycling in Si-O isotopes of Earth's oldest rocks 4 Ga ago
Identifying the oldest evidence for the recycling of hydrated crust into magma on Earth is
important because it is most effectively achieved by subduction. However, given the sparse …

High silica granites: Terminal porosity and crystal settling in shallow magma chambers
Abstract High silica (> 70 wt.% SiO 2) granites (HSGs) are important carriers of highly
incompatible elements, thus, understanding their origin is relevant to understanding how the …
