Noble gases within the crust originate from three main sources: the atmosphere, introduced
into the crust dissolved in groundwater; the mantle, in regions of magmatic activity; and …

Helium and argon isotopic and elemental compositions of fluids released by crushing pyrite
grains are reported from the Ailaoshan Gold Province, China. The province is a series of …

The Xiangshan U deposit, the largest hydrothermal U deposit in China, is hosted in late
Jurassic felsic volcanic rocks although the U mineralization post dates the volcanics by at …

The Red River–Jinshajiang strike-slip fault zone on the eastern margin of the Tibetan
plateau was originally produced by the India–Eurasia collision∼ 60–70 Myr ago. Numerous …

Abstract The Muruntau gold deposit, Uzbekistan, is one of the largest gold deposits known
worldwide, but its origin remains controversial. We used Re-Os arsenopyrite geochronology …

Helium trapped in arsenopyrite and wolframite from the Panasqueira hydrothermal deposit
in central Portugal is overwhelmingly—≈ 75%—derived from the mantle. This is surprising …

Fluid inclusions provide the only means possible for sampling fluids from the Earth's deep-
