Comparative Study of Gacun and Youre Silver–Lead–Zinc–Copper Deposits in Sichuan, SW China, and their Mineralization Significance
ore-bearing horizon structure of ore-bearing belt VMS deposit Gacun–Youre ore district
2018/4/10
The large Gacun silver–lead–zinc–copper deposit in Sichuan Province is one of the largest volcanogenic massive sulfide (VMS) deposits in China. The deposit consists of western and central ore bodies, ...
Discovery and significance of Quaternary aqueously deposited aeolian sandstones in the Sanhu area, Qaidam Basin, China
Qaidam Basin Qigequan Formation Aqueously deposited Aeolian sandstones Paleoclimate
2018/4/2
Influenced by neo-tectonic movement, the Sanhu area of China’s Qaidam Basin formed in the Quaternary in response to migration of its depocentre. A study of core material from the Qijia 1 Well reveals ...
Nucleosynthetic isotope anomalies and their cosmochemical significance
isotope anomalies nucleosynthetic effects metal isotopes
2017/4/10
Unlike most terrestrial rocks, some meteorites and their mineral components show isotope compositions that are clearly
associated with nucleosynthetic processes in stars other than the Sun. Although ...
Significance test for seismicity rate changes before the 1987 Chiba-toho-oki earthquake (M 6.7) Japan
quiescence seismicity rate increasa quantitative analysis significance test the 1987 Chiba-toho-oki earthquake
2015/9/30
A precursory seismic quiescence lasting 1.5 ± 0.5 years was observed prior to the 1987 M 6.7 Chiba-toho-oki earthquake, Central Japan. This event was the largest mainshock to occur in the region in 60...
The largest magnitudes of earthquakes associated with some historical volcanic eruptions and their volcanological significance
Earthquake magnitudes distance of perceptibility 1815 eruption of Tambora 1883 eruption of Krakatau magmatotectonic earthquakes
2015/9/28
We know several reports of earthquake swarms associated with volcanic eruptions in the 19th century or older periods when seismographs were not yet available. Even if we have no seismographs, the larg...
Crude oil He and Ar isotopic characteristics and their geochemical significance: an example from the Gangxi oil field in the Huanghua depression
crude oil noble gas tracing Gangxi oil field Huanghua depression
2015/9/10
Sampled from the Gangxi oil field in the Huanghua depression, Bohaiwan Basin, the crude oil He and Ar isotopic
compositions and their geochemical significance were investigated. The result shows that...
This paper discusses the problem of identifying di erentially expressed groups of genes from a microarray experiment. The groups
of genes are externally de ned, for example, sets of gene pathways

The Prediction,Verification,and Significance of Flank Jets at Mid-Ocean Ridges
Prediction Verification Significance Flank Jets Mid-Ocean Ridges
2015/7/14
One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows. Those unidirectional flows take the fo...
The significance of Fe(III) reducing bacteria in U(VI) bioremediation and energy production by sediment fuel cells
Iron metabolism sedimentary environments uranium contaminated sediments geochemistry pathogenic bacteria
2015/1/28
Dissimilatory Fe(III) reduction is one of the most significant metabolisms in sedimentary environments. Molecular and geochemical studies conducted on uranium contaminated sediments suggested that Fe(...
We have used new and archival infrared and radio observations to search for a dwarf galaxy associated with the high-velocity cloud (HVC) known as `complex H.' Complex H is a large (Ω gtrsim 400 deg2) ...

2014/11/12
Achankovil shear zone is a major tectonic crustal segment of south India.The recently
observed gas bubbles streaming water jets in the ponds along the shearzone and the minor
tremors released betw...
Depth-diameter ratios of lunar craters from chandrayaan-1 TMC images and DEM and its significance
Chandrayaan-1, TMC Depth-Diameter
2014/11/11
The most common features observed on the lunar surface are its craters. They differ from each
other in terms of age, composition and origin. Craters are the crustal depressions or areas of
negativ...
Significance of Water-Related Features on Mars
