Crustal flow, exhumation and fault reactivation may hinder river incision and help preserve orogenic plateaus, according to a combination of thermochronology and numerical modelling applied to the Yarlung River in the southern Tibetan plateau
Ferromanganese oxides formed by hydrothermal activity have been collected from a petit-spot volcano that erupted on an old and cold oceanic plate prior to subduction. This is the first evidence of hydrothermal activity due to the deepest submarine volcanism.
Mountains act as natural water towers, influencing the water cycle by storing snow until the melt season when downstream demand is high. We calculate and track historic changes in the degree to which mountainous snowpacks delay the timing and amount of water availability relative to precipitation.
