Picrite Evidence for Fe-Rich Heterogeneities in Archean Mantle
Terrestrial basalts generally have low FeO content, but Archean mafic/ultramafic rocks show high FeO levels inconsistent with typical sources. Neoarchean Fe-rich magmatism is observed, with ferropicrites displaying unique geochemical characteristics. This study explores the widespread presence of Fe

Geology and Magmatism in Canadian Cordilleran Terranes
The content discusses the geological features of Cordilleran terranes in Canada, including the Stikine and Quesnel arcs, Cache Creek, Slide Mountain, and more. It delves into the relationship between magmatism, porphyry mineralization, and subduction processes, highlighting the Kutcho-Sitlika-Venabl

Understanding the Low Velocity Layer (LVZ) in Subduction Zones
The presence of a Low Velocity Layer (LVZ) at the top of subducting plates in subduction zones has significant implications for imaging and potentially seismogenesis. This hydrated layer of oceanic crust, likely caused by dehydration reactions during subduction, affects seismic wave behaviors and ca
