Photos improve understanding volcanic processes
2020/7/24
The shapes of volcanoes and their craters provide critical information on their formation and eruption history. Techniques applied to photographs -- photogrammetry -- show promise in correlating shape...
Fluid Evolution and Ore-forming Processes of the Jiama Cu Deposit, Tibet: Evidence from Fluid Inclusions
fluid inclusion fluid evolution ore-forming processes Jiama deposit Tibet
2018/4/10
The Jiama deposit is a large copper deposit in Tibet. Mineralization occurs in three different host rocks: skarn, hornfels and porphyry. A detailed fluid inclusion study was conducted for veins in the...
The Dihedral Angle and Intersection Processes of a Conjugate Strike-Slip Fault System in the Tarim Basin, NW China
Conjugate fault strike-slip dihedral angle fault intersection faulting process Carbonate
2018/4/10
Recent studies, focused on dihedral angles and intersection processes, have increased understandings of conjugate fault mechanisms. We present new 3-D seismic data and microstructural core analysis in...

Long time-series of chemical and isotopic compositions of Vesuvius fumaroles: evidence for deep and shallow processes
Chemical and isotopic composition mount Vesuvius jet orifice
2015/8/27
Long time-series of chemical and isotopic compositions of Vesuvius fumaroles were acquired in the framework of the volcanic surveillance in the 1998-2010 period. These allow the identification of proc...

The production, transport and deposition of sediment occur to varying degrees on Earth, Mars, Venus, and Titan. These sedimentary processes are significantly influenced by climate that affects product...
Illite authigenesis - new constrains on fundamental clay crystallization processes using the NANOKIN code
Illite authigenesis new constrains fundamental clay crystallization processes the NANOKIN code
2012/3/30
Illite clay formation occurs widely in sedimentary basins. Illite is formed mainly in low-temperature environments where mineral reactions are governed by kinetics rather than equilibrium thermodynami...
Dissolution processes of elements from subducting sediments into fluids: Evidence from the chemical composition of the Sanbagawa pelitic schists
element mobility subduction zones pelitic schists
2017/4/12
In order to evaluate the dissolution processes of elements from subducting sediments into fluids during early stages of
metamorphism (up to oligoclase–biotite zone at about 30 km depth), the chemical...
Sorption Characteristics of CO2 on Rocks and Minerals in Storing CO2 Processes
Sorption Characteristics Rocks Minerals Storing CO2 Processes CO2 Geological Storage
2013/3/8
As CO2 is injected into pore spaces of water-filled reservoir rocks, it displaces much of the pore fluids. In short terms (several to tens of years), the greater part of the injected CO2 is predicted ...
An analogue model of melt segregation and accumulation processes in the Earth's crust
analogue modelling melt segregation migmatites fractals self-organized criticality
2009/10/21
An analogue experiment was carried out to model melt segregation from the solid rock matrix and its subsequent transport. Carbon dioxide gas and sand were used as analogue materials of crustal partial...
