Two Types of Granites in the Western Yangtze Block and Their Implications for Regional Tectonic Evolution: Constraints from Geochemistry and Isotopic Data
I-type granite S-type granite geochemistry petrogenesis tectonic setting Western Yangtze Block
2018/4/10
In the western Yangtze Block, widespread Mesoproterozoic to Neoproterozoic rocks are the key to understanding the Precambrian tectonic-magmatic evolution of the region. However, their petrogenesis and...
Multivariate analysis for geochemical process identification using stream sediment geochemical data: A perspective from compositional data
geochemical process identification k-means robust factor analysis Nanling belt log ratio transformation
2017/4/10
Identification of underlying geochemical processes based on samples of different types such as stream sediments,
soils, and water is important for a range of applications including mineral exploratio...
The Benthic Boundary Layer: geochemical and oceanographic data from the GEOSTAR-2 observatory
geochemical data oceanographic data Benthic Boundary Layer
2015/9/7
Geochemical and oceanographic data, acquired throughout 6 months by the GEOSTAR-2 benthic observatory in southern Tyrrhenian Sea, evidenced ocean-lithosphere interactions in the 1900-m deep Benthic Bo...
Anomalous pattern of geochemical data recorded in the seismically active site of Pieschi (Southern Italy)
earthquakes geochemical signals time series
2015/9/2
This work explores three years of geochemical signals recorded by Pieschi station (Southern Italy). The measuring
station is located in a thermal spring located in the Southern Apennines Chain, one o...
Statistical evaluation of the geochemical data from Akoluk epithermal gold area (Ulubey–Ordu), NE Turkey
Soil geochemistry exploration epithermal gold deposit Akoluk–Ordu
2017/4/12
The Akoluk gold mineralization area is located in the southern section of the western Pontide tectonic belt in the
northeast of Turkey. The area of interest is intensely vegetated with hazelnut trees...
Effect of organic matrices on the determination of the trace element chemistry (Mg, Sr, Mg/Ca, Sr/Ca) of aragonitic bivalve shells (Arctica islandica) —Comparison of ICP-OES and LA-ICP-MS data
trace elements bivalve shell organics LA-ICP-MS ICP-OES sclerochronology
2017/8/9
The element chemistry of biogenic carbonates can provide important data on past environments. However, the Sr/Ca and Mg/Ca ratios as well as the Mg and Sr concentrations of biological carbonates, espe...
A novel iterative approach for mapping local singularities from geochemical data
novel iterative approach local singularities geochemical data
2009/11/3
There are many phenomena in nature, such as earthquakes, landslides, floods, and large-scale mineralization that are characterized by singular functions exhibiting scale invariant properties. A local ...
The succession of Hirnantian events based on data from Baltica:brachiopods,chitinozoans,conodonts,and carbon isotopes
Hirnantian Baltica brachiopods chitinozoans conodonts graptolites carbon isotopes
2009/10/21
The Hirnantian (late Ordovician) environment was complex and dynamic. Understanding the correct order of events and their precise correlation with a time scale are extremely important for the developm...
New biostratigraphic and chemostratigraphic data from the Chicotte Formation (Llandovery,Anticosti Island,Laurentia) compared with the Viki core (Estonia,Baltica)
conodonts stable carbon isotopes Anticosti Estonia Llandovery Telychian
2009/10/21
Due to the lack of biostratigraphically useful graptolites in the crinoidal and reefal Chicotte Formation on Anticosti Island (Québec, Canada), the precise chronostratigraphic position of the formatio...
Anomalous Strong Reflections on High Resolution Seismic Data from the Turkish Shelf of the Eastern Black Sea: Possible Indicators of Shallow Hydrogen Sulphide-Rich Gas Hydrate Layers
Black Sea gas hydrate hydrogen sulphide high-resolution acoustic methods
2009/7/7
Some strong reflections about 3 to 5 m thick were observed at depths of 25-60 metres below the sea floor using deep-towed, 5 kHz subbottom profiler data in the Turkish shelf and upper slope of the Ea...
