Petrographic and geochemical evidence from pyrite for the genesis of the Bainiuchang Ag-polymetallic deposit southeastern Yunnan [PDF]

open access: yesScientific Reports
Southeastern Yunnan lies within a composite zone at the convergence of the South China, Yangtze, and Indochina (Tibet-Yunnan) blocks. Its complex regional structure provides favorable conditions for metallogenesis, making it a major metallogenic province

Ferrosilicide as indicator of mineral composition of the Earth mantle?

open access: yesГеофизический журнал, 2020
The creation of plausible model of the Earth mantle is the urgent problem. Now there are different its models. According to canonical model of the Earth mantle it is rock oxide-silicate cover (the majority of geologists and geophysicists have adhered to

Linking the flow-induced tremor model to the seismological observation: application to the deep harmonic tremor at Hakone volcano, Japan

open access: yesEarth, Planets and Space, 2023
Decades ago, Julian (J Volcanol Geotherm Res 101:19–26, 1994. https://doi.org/10.1029/93JB03129 ) proposed the lumped parameter model of non-linear excitation of an elastic channel vibration by fluid flow as a mechanism of volcanic harmonic tremor. Since

The transition zone as a host for recycled volatiles: Evidence from nitrogen and carbon isotopes in ultra-deep diamonds from Monastery and Jagersfontein (South Africa) [PDF]

open access: yes, 2017
Sublithospheric (ultra-deep) diamonds provide a unique window into the deepest parts of Earth's mantle, which otherwise remain inaccessible. Here, we report the first combined C- and N-isotopic data for diamonds from the Monastery and Jagersfontein ...
