Mesoproterozoic magma events in the Bayan Obo rift belt have remained poorly constrained and as a result, the Late Paleoproterozoic–Mesoproterozoic tectonic evolution of the rift belt has remained unclear. By a multiple-facetted regional geological investigation of this belt, we have resolved the stratigraphic sequence and geochronology of the Bayan Obo Group and made new discoveries including a three-stage mantle-derived magmatic sequence. Zircon and baddeleyite dating of Xiaonanshan hornblende pyroxenite emplaced into the Bayan Obo Group yields 207Pb/206Pb ages of ca. 1.34 and 1.33 Ga. The geochronological, geochemistry, Hf isotopic analyses place an important constraint on ages of the Late Paleoproterozoic–Mesoproterozoic strata and the evolution of the rift belt. Our field observations and U-Pb dating results suggest that mineralization is genetically related to Mesoproterozoic magmatism in North China Craton, i.e., 1.33–1.34 Ga. The δ34SV-CDT values of sulphide from the ore-bearing ultra-/mafic samples are about 6.2‰, whereas the 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb values vary in the ranges of 17.598–18.115, 15.496–15.501, and 37.478–37.952, respectively. The Late Paleozoic mafic gabbro and acidic granite porphyry intrusions are possible to bimodal magmatic event related to the extensional tectonic setting of the Central Asia in this period.

The Cu/ZnO flower-like hierarchical porous structures were successfully synthesized via the cetyltrimethyl ammonium bromide(CTAB) assisted hydrothermal method. The morphology and structure as well as the catalytic performance for dimethyl oxalate(DMO) hydrogenation to ethylene glycol(EG) were investigated. Through annealing the zinc copper hydroxide carbonate(ZCHC) precursors, the Cu/ZnO flower-like hierarchical porous structures were obtained, which were assembled by a number of porous nanosheets. The catalyst made of these well-defined flower-like hierarchical porous structures with large specific surface area and effective gas diffusion path via the well-aligned porous structures showed higher EG selectivity and yield as compared to the Cu/ZnO catalyst obtained by conventional co-precipitation technique. The results indicated that the Cu/ZnO flower-like hierarchical porous structures have excellent potential application for manufacture of high performance catalysts.

The Meso–Neoproterozoic Bayan Obo Rift is located along the northern margin of the North China Craton， and was associated with the break-up of the Columbia supercontinent. During rift evolution， syn-sedimentary deformation occurred due to tectonic activity and earthquakes. Seismic events are recorded in the Jianshan Formation of the Bayan Obo Group， Inner Mongolia， as soft sediment deformation structures in the central Bayan Obo Rift. Druse calcite crystals and collapse breccias in the Jianshan Formation may provide information on the rift evolution. The druse calcite crystals are idiomorphic–columnar in shape and associated with graphite， pyrite， and quartz. δ13C values of the graphite are –20‰， indicative of biogenic deoxygenation and formation in water. The druse calcite crystals are inorganic in origin and formed in water at a temperature of 55?C， based on calcite δ13C and δ18O data. The calcite grew in paleo-caves containing fault breccias， with heat derived from faulting. As such， the druse calcite crystals are important evidence for seismic events. The collapse breccias （i.e.， fault breccias） and other indicators of slip show that displacement occurred from NE to SW， which is different from the paleocurrent direction in the Jianshan Formation. The thickness of the collapse breccia is ～200 m， which represents the height of the fault scarp. The strike of the fault scarp was NE–SW， based on the distribution of the collapse breccia. The Bayan Obo and Yanliao rifts experienced rapid NW–SE extension， and developed similar deformation structures at ca. 1.6 Ga related to break-up of the Columbia supercontinent.

The Xing’an–Inner Mongolia Orogen is a critical tectonic unit for constraining the evolution of the Paleo-Asian Ocean. However， the location and time for the closure of the Paleo-Asian Ocean are still debated. Here， we select a representative basin in Dashizhai in northeastern China， using U-Pb zircon geochronology and geochemistry to analyze the sedimentary facies， depositional ages， and provenance. The results show that the age of the Dashizhai Formation range from 400 to 347 Ma， the Shoushangou Formation range from 400 to 348 Ma， the Zhesi Formation range from 307 to 252 Ma， and the Linxi Formation range from 299 to 241 Ma. The Dashizhai Formation is composed of metamorphic andesite and clastic rocks. The Shoushangou Formation comprises siltstone， rhyolite， and argillaceous siltstone. The Zhesi and Linxi Formations are composed of mudstone and argillaceous siltstone. Geochemical data shows that these rocks are enriched in light rare earth elements and depleted in Eu with various La/Sc， Th/Sc， and La/Co ratios. The Permian Dashizhai Basin is from Permian volcanic and felsic igneous rocks from the Ergun， Xing’an， and Songliao blocks. The absence of the Late Carboniferous strata in the Dashizhai Basin indicates an extension setting during this period. Furthermore， we suggest the Xing’an–Inner Mongolia Orogen was an uplifting process associated with evolution the Paleo-Asian Ocean during the Late Permian.
