Geology and mineralization of the Dayin’gezhuang supergiant gold deposit (180 t) in the Jiaodong Peninsula, China: A review

China Geology, 2022
The Dayin’gezhuang gold deposit is located in the central part of the Zhaoping Fault metallogenic belt in the Jiaodong gold province —the world ’s third-largest gold metallogenic area. It is a typical successful case of prospecting at a depth of 500‒2000

Komatiites: From Earth's Geological Settings to Planetary and Astrobiological Contexts [PDF]

arXiv, 2005
Komatiites are fascinating volcanic rocks. They are among the most ancient lavas of the Earth following the 3.8 Ga pillow basalts at Isua and they represent some of the oldest ultramafic magmatic rocks preserved in the Earth's crust at 3.5 Ga. This fact, linked to their particular features (high magnesium content, high melting temperatures, low dynamic

Hanohano: A Deep Ocean Anti-Neutrino Detector for Unique Neutrino Physics and Geophysics Studies [PDF]

arXiv, 2008
The science potential of a 10 kiloton deep-ocean liquid scintillation detector for ~1 MeV energy scale electron anti-neutrinos has been studied. Such an instrument, designed to be portable and function in the deep ocean (3-5 km) can make unique measurements of the anti-neutrinos from radioactive decays in the Earth'.s mantle.

Mantle heterogeneity controls on small-volume basaltic volcanism

Geology, 2015
Eruptions of basaltic material in small-scale volcanic fields located in intraplate settings display a very diverse range in physical and chemical characteristics. Despite its relevance to the understanding of volcanic hazards, the relationship between physical properties of eruptions (explosivity, volume, location) and chemical composition of erupted ...
