Investigating the temporal fluctuations in geoelectrical and geochemical signals Jointly measured in a seismic area of Southern Apennine chain (Italy)
geoelectrical and geochemical signal scaling power spectral analysis
2015/9/28
We analyse geoelectrical and geochemical time series jointly measured by means of a multiparametric automatic station close to an anomalous fluid emission in Val d'Agri (Basilicata, Southern Italy). I...
The November 2002 degassing event at Panarea Island (Italy): five months of geochemical monitoring
Aeolian Islands Panarea submarine fumaroles gas chemistry geochemical monitoring
2015/9/10
On 3rd November 2002, at about 3 km off-shore of Panarea Island (Aeolian Islands, Southern Italy), a series of
gas vents suddenly and violently opened from the seafloor at the depth of 10-15 m, with ...
Geochemical modeling of magmatic gas scrubbing
magmatic gas magma degassing hydrothermalsystem crater lake meteoric water scrubbing reaction path modeling
2015/9/10
The EQ3/6 software package, version 7.2 was successfully used to model scrubbing of magmatic gas by pure
water at 0.1 MPa, in the liquid and liquid-plus-gas regions. Some post-calculations were neces...
Investigating correlations of local seismicty with anomalous geoelectrical, hydrogeological and geochemical signals jointly recorded in Basilicata Region (Southern Italy)
self-potential records gas flow seismicity fluids precursor effects
2015/9/2
This paper presents the preliminary results analysing the correlation between local seismicity and geoelectrical, hydrogeological
and geochemical signals concomitantly recorded in Basilicata Region, ...
Geochemical features and effects on deep-seated fluids during the May-June 2012 southern Po Valley seismic sequence
Fluids Geochemistry Faults Temporal changes
2015/8/26
A periodic sampling of the groundwaters and dissolved and free gases in selected deep wells located in the area affected by the May-June 2012 southern Po Valley seismic sequence has provided insight i...
Factors controlling the geochemical composition of Limnopolar Lake sediments (Byers Peninsula, Livingston Island, South Shetland Island, Antarctica) during the last ca. 1600 years
Lake sediments Limnopolar high resolution element analysis mineral composition energy dispersive x ray spectrometer glass mineral particles
2015/1/6
We sampled a short (57 cm) sediment core in Limnopolar Lake (Byers Peninsula, Livingston Island, South Shetland Islands), which spans the last ca. 1600 years. The core was sectioned at high resolution...
Increase in acetate concentrations during sediment sample onboard storage: a caution for pore-water geochemical analyses
acetogen microbial community pore water marine sediment storage condition
2017/4/11
Microbial activity in marine sediment plays an important biogeochemical role in cycling of carbon and other elements.
Acetate is a key intermediate of various microbial metabolic pathways. In this st...
Long range gas-geochemical anomalies of a remote earthquake recorded simultaneously at distant monitoring stations in India
thermal spring gas-geochemical monitoring
2017/4/12
Continuous He, 222Rn concentrations and gamma dose rate were simultaneously monitored for pre-seismic signatures
at two thermal springs in India that are separated at a distance of approximately 1612...
Arbitrary scaling in ISOCON method of geochemical mass balance: An evaluation of the graphical approach
least squares regression volume factor alteration mass balanc
2017/8/10
Rock alteration processes can be studied through geochemical Mass Balance (MB) estimation in several ways. Due to the ease of its adaptability, especially its graphical approach, the ISOCON method of ...
