Arc Heat Flow and Magmatic Heat Budgets
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...

Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.
