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, ...
Paleomagnetic dating of non-sulfide Zn-Pb ores in SW Sardinia (Italy): a first attempt
paleomagnetism non-sulfideores calamine Sardinia
2015/9/10
A first paleomagnetic investigation aimed at constraining the age of the non-sulfide Zn-Pb ore deposits in the
Iglesiente district (SW Sardinia, Italy) was carried out. In these ores, the oxidation o...
VLF-EM and VES: an application to groundwater exploration in a Precambrian basement terrain SW Nigeria
Electromagnetic (VLF-EM) Hard rock environment Groundwater development Layer resistivity Bed thickness mappingss mapping
2015/8/17
In a hard rock environment with surface or near surface expression of outcrops, the use of VES only becomes difficult due to its associated problems and limitations. However, the use of VLF-EM becomes...

zircon geochronology Hekou Group Yangtze Block supercontinent Columbia
2017/4/11
The Hekou Group, an outcrop at the west margin of the Yangtze Block, consists of volcanic and sedimentary rocks of
sodic lava, sodic pyroclastic rocks, coarse to fine-grained siliciclastic rocks and ...
Frame-dragging, disk warping, jet precessing, and dipped X-ray lightcurve of Sw J1644+57
Frame-dragging disk warping jet precessing dipped X-ray lightcurve Sw J1644+57
2012/2/23
The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events, the...
Maastrichtian Rudist Fauna from Tarbur Formation (Zagros Region, SW Iran): Preliminary Observations
Tarbur Formation Preliminary Observations
2010/12/20
The uppermost Cretaceous Tarbur Formation of the Zagros region (SW Iran) is mainly siliciclastic in composition, though it also incorporates some carbonate units including several rudist lithosomes.
Oligocene history of the Çardak - Dazkırı subbasin (Denizli, SW Turkey): Integrated molluscan and planktonic foraminiferal biostratigraphy
Oligocene history of the Ç ardak Integrated molluscan planktonic foraminiferal biostratigraphy

The detailed analysis of molluscan and planktonic foraminiferal fauna in the Oligocene Çardak-Dazkırı sub-basin, in northeastern Denizli provin ce (western Turkey) allowed accurate da...
Testing Miocene Remagnetization of Bey Dağları: Timing and Amount of Neogene Rotations in SW Turkey
Aegean orocline palaeomagnetism IRM component analysis remagnetization
2010/10/14
Here we reassess the timing and amount of rotation of the eastern limb of the Aegean orocline, located in SW Turkey. The current model for this orocline involves a 25-30° counterclockwise (CCW) rotati...
