Abstract We report new results of a combined focused ion beam high-resolution transmission electron microscopy (FIB/HRTEM) investigation of two grains of platinum-group minerals (PGM) corresponding to the laurite (RuS2)-erlichmanite (OsS2) solid solution series. The grains are included within unaltered chromite and the serpentine-dominant matrix of the mantle-hosted chromitite body of Monte Bueno in eastern Cuba. At the micron-scale, the grain hosted in unaltered chromite preserves magmatic feat...

Abstract Zhengguang is a partly eroded (about ≥500 m being eroded), structurally controlled intermediate sulfidation (IS) epithermal gold-zinc deposit, characterized by wide distribution of base metal sulfides, Fe-poor sphalerite and Mn-calcite, hosted by the Late Cambrian-Early Ordovician basaltic-andesitic volcanic and volcano-sedimentary rocks in northeast China. The deposit is located 4 and 8 km from the Early Ordovician Tongshan and Duobaoshan porphyry copper deposits, respectively. A 484.8...

Abstract The Hongshanliang copper deposit, hosted in the tuff of the Lower Carboniferous Yamansu Formation, is a typical copper deposit in the Aqishan–Yamansu belt, East Tianshan. Based on crosscutting relationships of veins, textural relationships and mineral assemblages, five alteration/mineralization stages at Hongshanliang have been established: chlorite–sulfide stage (Stage I), quartz–pyrite stage (Stage II), quartz–polymetallic sulfide stage (Stage III), late veins (Stage IV) and supergene...

Abstract The Larong porphyry W-(Mo) deposit, formed in the main collisional orogenic stage of Lhasa and Qiangtang terranes, is the first-discovered giant W-(Mo) deposit in the Leiwuqi-Zogang metallogenic belt, Sanjiang region. The W-Mo mineralization occurs as veins and stock-works mainly hosted in the granodiorite porphyry, monzogranite porphyry, biotite granite porphyry, and surrounding schist. Four types of fluid inclusions (FIs) including PC-type (pure vapor CO2), C-type (CO2-H2O), W-type (a...

Abstract The Bilihe gold deposit is a rare example that economical gold mineralization occurred in unidirectional solidification textures (UST) quartz at the cupola of middle Permian granodioritic intrusion. However, there is a key dispute about whether gold precipitated from low-diffusion silicate melt or high-activity fluid phase. In this paper, based on in-situ trace elements analyzing, SEM-CL mapping, and infra-red and Raman spectroscopy, the magmatic fluids are supposed to play a critical r...

Abstract The Philippine island arc is famous for the widely developed large porphyry and epithermal Cu-Au deposits and associated Cenozoic adakites/adakitic rocks. Northern Luzon is one of the most Cu-Au enriched areas in the Philippines, which develops Late-Oligocene to Pleistocene porphyry and epithermal Cu-Au deposits in the Central Cordillera Range and southernmost of Cagayan Valley Basin. In this paper, Cenozoic magmatic events and geological characteristics of typical porphyry and epitherm...

Abstract The Tongkeng tin-polymetallic ore deposit in Nandan County, Guangxi Zhuang Autonomous Region, southern China, is the representative deposit of the largest scale in the famous Dachang tin-polymetallic ore field. It consists of the upper tin-polymetallic ores and the lower newly found zinc-copper ores with the Sn metal reserve of 680,000 tons (average grade 1%), 4,500,000 tons of Zn (average grade 4%), and 80,000 tons of Cu (average grade 0.2%). The orebodies occur as layers and veins wit...

Abstract The Wuxing mafic-ultramafic complex is located in the eastern part of the Central Asian Orogenic Belt (CAOB). It consists of hornblende-olivine clinopyroxenite, hornblende clinopyroxenite, clinopyroxenite, gabbro and diorite. Hornblende occurs in all the rock types of the complex and is pargasite in composition. Clinopyroxene is diopsidic in composition with high CaO and low TiO2 contents. The flat REE and sub-parallel trace element patterns of both clinopyroxene and hornblende suggest ...

Abstract Northern Laos is at the junction of the Paleo-Tethys convergence and assemblages of several crustal blocks such as the Sibumasu, South China and the Indochina blocks, and also comprises the Houayxay-Sukhothai, the Simao-Phongsaly, the Louang Phrabang-Loei, the Truong Son and the Song Da terranes. During the amalgamation of the terranes derived from Gondwana, calc-alkaline magmatic rocks, peraluminous magmatic rocks, sub-alkaline volcanic-intrusive complexes, and alkaline rocks and relat...

Abstract This study employed high-sensitivity and high-resolution secondary ionizing mass spectrometry (NanoSIMS) to determine the distribution of Au, As, Cu, Se, and S isotopes of pyrite from the Shuiyindong Au deposit, southwestern China. NanoSIMS maps show that Au occurs as solid solution, and heterogeneously distributes at micron scale in the ore pyrite, which is the overgrowth of the preexisting synsedimentary or hydrothermal pyrite core, commonly rimmed again by the As- and Au-poor outermo...
