Abstract The East Kunlun Orogen is located in the northern part of the Tibetan Plateau and has received significant attentions in tracing the evolution of Paleo-Tethys Ocean. In this study, we present U Pb zircon geochronology, geochemistry and Sr Nd isotopic data on the Kengdenongshe tholeiitic gabbro in the eastern part of the orogen. The gabbro is characterised by high and variable MgO and Fe 2 O 3 , as well as low K 2 O and TiO 2 contents, typical of low-K tholeiitic series. The rock shows e...

Abstract The Himalayan mineral field includes over 50 quartz-vein type Sb-Au deposits, and placer Au deposits. The poorly documented Laqiong deposit is a typical example of quartz-vein type Sb-Au mineralisation in Tethys Himalayan sequence. The orebody are controlled by shallow north-dipping normal faults and north–south trending faults. Magmatic zircons extracted from muscovitic leucocratic granite from the southern part of the Laqiong mine area yield a Laser Ablation-Inductively Coupled Plasma...

Abstract GeoPyTool is an open source application developed for geological calculations and plots, such as geochemical classification, parameter calculation, basic statistical analysis and diagrams for structural geology. More than acting as a link from raw data stored in Microsoft Excel ® (MS Excel) files to vector graphic files, GeoPyTool includes recently developed routines that have not been included in previous software, such as the calculation of the Ce (IV) /Ce (III) ratio for zircons as a...

Abstract Many Mesozoic Mo-bearing granites, present along the northern margin of the Precambrian North China Block (NCB) and Phanerozoic Xing'an-Mongolian Belt (XMB) within the Central Asian Orogen (CAO) have hydrated sources. These granites are temporally and spatially related to biotite-rich mafic, alkali syenitic plutons, are highly evolved, have an arc-like trace element geochemical pattern, and were emplaced between ca. 245–129 Ma bracketed by A 2 - and A 1 -type granites. This conflicts te...

Abstract The large Bilugangan porphyry Mo deposit is one of the oldest Mo deposit in eastern part of the Central Asian Orogen in Inner Mongolia. The orogen is currently regarded as the most important Phanerozoic region with widespread crustal growth between the Siberian Craton to the north, and North China Block to the south. The Bilugangan Mo mineralisation is hosted by a porphyritic monzogranite and along the contact with the Late Permian Linxi Formation. The mineralisation is disseminated in ...

Abstract The newly discovered Shuangjianzishan Ag-polymetallic deposit is in the southern part of the Great Xing’an Range of Inner Mongolia in NE China, and is China’s largest Ag deposit with a 21,665 t silver reserves. Three types of hydrothermal mineralization are evident: relatively early disseminated and stringer mineralization, succeeded by a breccia-hosted and younger vein-type mineralization. Preliminary studies show that the deposit might represent a mixed ore system where the early diss...

ABSTRACTAs the north part of Simao Terrane, Lanping Basin is located between the Sanjiang Tethys Orogen (STO) and Yangtze Block, also the junction zone between the Gondwanaland and Cathaysian old land (Pan Huaxia mainland), which includes Yangtze and Cathaysian Blocks. The aim of this study is to decipher the provenance of the sedimentary units in the Lanping Basin and affiliation of Simao Terrane by the U-Pb ages, Hf isotope of detrital zircons and whole-rock geochemistry. The whole-rock geoche...

The Caojiaba tungsten deposit (19.03 Mt@ 0.37 wt% WO3) is hosted by skarn along the contact between clastic and carbonate rocks in the Xiangzhong Metallogenic Province of southern China. The deposit is characterized by an early prograde skarn containing low andraditic garnet (Ad0.7–21.9) and hedenbergitic pyroxene (Hd52.9–77.3) overprinted by a retrograde biotite–chlorite assemblage and then by quartz–scheelite veins, similar to well-studied reduced tungsten skarns worldwide. Scheelite has low M...
