2018/4/10
The special seismic tectonic environment and frequent seismicity in the southeastern margin of the Qinghai–Tibet Plateau show that this area is an ideal location to study the present tectonic movement...
New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
Heat and mass transfer from the mantle: heat flow and He-isotope constraints

From the Mantle to Microbes: The Lost City Hydrothermal Field
Lost City Hydrothermal Field Microbes
2015/7/28
For over two decades, explorers of the deep ocean have been enthralled by volcanically driven black smoker hydrothermal systems hosting organisms that live under some of the most extreme conditions on...
Past and Future Impact of Deep Drilling in the Oceanic Crust and Mantle
Past and Future Deep Drilling Oceanic Crust and Mantle
2015/7/24
Knowledge of the composition of oceanic crust is critical for calculating the fluxes of mass, heat, and volatiles from Earth's interior to its crust, oceans, and atmosphere. In the great debate over c...
Links from Mantle to Microbe at the Lau Integrated Study Site:Insights from a Back-Arc Spreading Center
Links from Mantle Microbe Lau Integrated Study Site Back-Arc Spreading Center
2015/7/14
The Lau Integrated Study Site (ISS) has provided unique opportunities for study of ridge processes because of its back-arc setting in the southwestern Pacific. Its location allows study of a biogeogra...
