Temperature and pressure gas geoindicators at the Solfatara fumaroles (Campi Flegrei)
Fluid pressure temperature hydrothermal system sulfur volcanic jet hole jet hole gas system

Long time series of fluid pressure and temperature within a hydrothermal system feeding the Solfatara fumaroles are investigated here, on the basis of the chemical equilibria within the CO2–H2O–H2–CO ...
Experimental study of rare earth element partitioning between calcite and sodium chloride solution at room temperature and pressure

The rare earth element (REE) partition coefficients between calcite and aqueous solution were obtained experimentally
under the conditions of pH, ionic strength and REE concentration level in the par...
Coral growth-rate insensitive Sr/Ca as a robust temperature recorder at the extreme latitudinal limits of Porites
skeletal oxygen isotope in the coral Sr/Ca high latitudes coral growth rates

2017/4/11
Oxygen isotope values of low-growth coral (<5 mm/yr) skeletons may reflect kinetic effects, which is problematic for
sea surface temperature (SST) reconstruction. Here, we report a Sr/Ca-based SST re...
Mid-Holocene sea-surface temperature reconstruction using fossil corals from Kume Island, Ryukyu, Japan

The relative warmth and stability of the Holocene was punctuated by several brief cold events. Whereas these cold
events on a global scale are widely reported, the lack of records from regions such a...
Closed-system programmed-temperature pyrolysis on n-octadecane: Implications for the conversion of oil to gas
n-octadecane pyrolysis experiment gaseous hydrocarbon stable carbon isotope kinetic

2017/8/10
The aim of this work is to determine the molecular and stable carbon isotope compositions of pyrolysates from normal octadecane and, then, to study methane generation kinetic and carbon isotope fracti...
