Genesis of the Baiyangping Cu–Co and Pb–Zn Mineralizations in Lanping Basin, SW China
The Oligocene to Miocene Baiyangping Cu–Co and Pb–Zn mineralization was deposited during the collision of the India and Asia continents. The mineralization is hosted in veins in faulted carbonate and clastic rocks, which act as fluid pathways. A detailed

High Precision Strontium Isotope Measurement of Rock Standard Materials by Multi-dynamic TIMS
BACKGROUNDStrontium isotopes are a powerful geochemical indicator for tracing the sources and ages of ore-forming materials. TIMS is internationally recognized as the “gold standard” for determining Sr isotopic compositions, however, its analysis ...

Analytical solution for residual stress and strain preserved in anisotropic inclusion entrapped in an isotropic host [PDF]
Raman elastic thermobarometry has recently been applied in many petrological studies to recover the pressure and temperature (P–T) conditions of mineral inclusion entrapment.

Complex Vulnerabilities of the Water and Aquatic Carbon Cycles to Permafrost Thaw
The spatial distribution and depth of permafrost are changing in response to warming and landscape disturbance across northern Arctic and boreal regions. This alters the infiltration, flow, surface and subsurface distribution, and hydrologic connectivity

Carbonation and serpentinization of diopsidite in the Altun Mountains, NW China
Mineral carbonation of mafic–ultramafic rocks has been highlighted as a promising way for permanent carbon capture and storage. Carbonatization involves the release of Ca, Mg and Fe from silicate minerals by dissolution and reaction in the aqueous phase ...

Mercury spikes suggest volcanic driver of the Ordovician-Silurian mass extinction
The second largest Phanerozoic mass extinction occurred at the Ordovician-Silurian (O-S) boundary. However, unlike the other major mass extinction events, the driver for the O-S extinction remains uncertain.

Nickel isotopic evidence for late-stage accretion of Mercury-like differentiated planetary embryos
Based on Nickel isotope analysis of meteorites and terrestrial rocks, the authors suggest that the Bulk Silicate Earth has a sub-chondritic Nickel isotope composition.

A new clinopyroxene thermobarometer for mafic to intermediate magmatic systems [PDF]
Clinopyroxene-only thermobarometry is one of the most practical tools to reconstruct crystallization pressures and temperatures of clinopyroxenes. Because it does not require any information of coexisting silicate melt or other co-crystallized mineral ...
