The newly discovered Paodaoling porphyry Au deposit from the Guichi region, Lower Yangtze River Metallogenic Belt （LYRB）, contains 〉35 tons of Au at an average grade of -1.7 g/t. It is a porphyry ＇Au-only＇ deposit, as revealed by current exploration in the depths, mostly above -400 m, which is quite uncommon among coeval porphyry mineralization along the LYRB. Additionally, there are also Cu-Au bearing porphyries and barren alkaline granitoids in the Paodaoling district. Zircon LA-ICP-MS U-Pb dating of the Cu-Au-bearing porphyries yield an age of 141-140 Ma, falling within the main magmatic stage of the LYRB, whereas the barren granites give an age of 125-120 Ma, coeval with the regional A- type granites. The Cu-Au-bearing porphyries are LILE-, LREE-enriched and HFSE-depleted, typical of arc magmatic affinities. The barren granites are HFSE-enriched, with lower LREE/HREE ratios and pronounced negative Eu anomalies. The Cu-Au-bearing porphyries in the Paodaoling district have high oxygen fugacities and high water content. Pyrite sulfur isotopes of the Paodaoling gold deposit indicate a magmatic-sedimentary mixed source for the ore-forming fluids. Based on the alteration and poly-metal zonation of the deepest exploration drill hole from the Paodaoling Au deposit, we propose that Cu ore bodies could lie at depth beneath the current Au ore bodies. The magmatism and associated Cu-Au mineralization of the Paodaoling district are likely to have formed in a subduction setting, during slab rollback of the paleo-Pacific plate.

Isotope Geochronologic and Geochemical Constraints on the Magmatic Associations of the Collisional Orogenic Zone in the West Kunlun Orogen, China

引用

Acta Geologica Sinica(English Edition) 2018年第2期92卷 482-498页

作者： WANG Chan LIU Hao deng jianghong LIU Xianfan ZHAO Fufeng WANG Chun TIAN Xin School of Earth Science Chengdu University of Technology Chengdu 610059 China State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation School of Energy Chengdu University of Technology Chengdu 610059 China The Geophysical Prospecting Team of Sichuan Geological & Mineral Bureau Chengdu 610072 Sichuan China

The Jiajiwaxi pluton in the southern portion of the West Kunlun Range can be divided into two collision-related intrusive rock series, i.e., a gabbro-quartz diorite-granodiorite series that formed at 224±2.0 Ma and a monzonitic granite-syenogranite series that formed at 222±2.0 Ma. The systematic analysis of zircon U-Pb geochronology and bulk geochemistry is used to discuss the magmatic origin （material source and thermal source）, tectonic setting, genesis and geotectonic implications of these rocks. The results of this analysis indicate that the parent magma of the first series, representing a transition from I-type to S-type granites, formed from thermally triggered partial melting of deep crustal components in an early island-arc-type igneous complex, similar to an I-type granite, during the continental collision orogenic stage. The parent magma of the second series, corresponding to an S-type granite, formed from the partial melting of forearc accretionary wedge sediments in a subduction zone in the late Palaeozoic-Triassic. During continued collision, the second series magma was emplaced into the first series pluton along a central fault zone in the original island arc region, forming an immiscible puncture-type complex. The deep tectonothermal events associated with the continent-continent collision during the orogenic cycle are constrained by the compositions and origins of the two series. The new information provided by this paper will aid in future research into the dynamic mechanisms affecting magmatic evolution in the West Kunlun orogenic belt.

Gene mutations and clinical phenotypes in Chinese children with Blau syndrome

作者： Caifeng Li Junmei Zhang Shipeng Li Tongxin Han Weiying Kuang Yifang Zhou jianghong deng Xiaohua Tan Department of Rheumatology and Immunology Beijing Children's Hospital Capital Medical University National Center for Children's Health Beijing 100045 China

The mutations of CARD15 gene and clinical features of Chinese patients with Blau syndrome were analyzed. We identified10 missense mutations, out of which five were new: R334 L, E383 D, R471 C, C495 R and D512 F. The rest of them, R334 W,R334Q, G481 D, M513 T and R587 C, have been reported previously. Among all the mutations, R334 W, R334 Q and C495 R had the highest frequency. Blau syndrome was found at early age after birth. It began with lepidic rash and symmetric polyarthritis and was phenotypically characterized by typical rash, arthritis, iridocyclitis and arteritis. Cardiac involvement was also found in Blau syndrome. In addition to nerve deafness, renal involvement, osteochondroma and central nervous system involvement were also found in our patients. Therefore, Chinese children with Blau syndrome have unique gene mutations and complicated clinical phenotypes. Pathologic examination and CARD15 mutation testing should be considered for diagnosis as early as possible for suspected patients.

Gene mutations and clinical phenotypes in 15 Chinese children with cryopyrin-associated periodic syndrome(CAPS)

Science China(Life Sciences) 2017年第12期60卷 1436-1444页

作者： Caifeng Li Xiaohua Tan Junmei Zhang Shipeng Li Wenxiu Mo Tongxin Han Weiying Kuang Yifang Zhou jianghong deng Department of Rheumatology and Immunology Beijing Children's HospitalCapital Medical UniversityNational Center for Children"s HealthBeijing 100045China

The aim of our study is to explore the features of clinical manifestations and genetic mutations in Chinese CAPS patients. Fifteen confirmed patients with CAPS were enrolled. The onset time ranges from 2 days after birth to 6 years and 1 month. Recurrent urticaria rash(93.3%) with fever(100%) were two dominant characteristics of these patients that were presented as either acute or chronic process. Systemic involvements were found in all patients except for one with only rash and fever. The top three symptoms were fever(100%), rash(93.3%) and myalgia(76%). Other clinical manifestations include arthritis(11 cases), lung involvement(seven cases), optical dysfunction(seven cases), nerve deafness(six cases), nervous system involvement(five cases), hepatomegaly, splenomegaly and lymphadenectasis(five cases). Also, four patients had heart involvement and one patient suffered kidney involvement. The laboratory inflammation index such as leukocyte counts, platelet counts, erythrocyte sedimentation rate(ESR), C-reactive protein(CRP), serum amyloid A(SAA) and fibrinogen(FIB) increased significantly at initial stage, but decreased after therapy. As for gene mutation detection, Twelve out of 15 patients were confirmed with mutation in NLRP3, including 11 mutant site: c1789 A>G, c.1703 T>A, c.913 G>A, c.1710 G>C, c.1057 G >T, c.2335 C>T, c.932 T>C,c.296 G>C, c.663 C>T, t.1702 T>A, 299 G>A. Mutation sites c.1703 T>A, c.2335 C>T, c.296 G>C, c.663 C>T, and 299 G>A were newly identified. The association between gene mutation and clinical manifestation shows that D305 N was highly associated with severe organs involvements, and therefore, the time of therapy and regimen were critical for the prognosis of disease. As the largest cohort study of Chinese CAPS patients, we confirmed that all patients presented typical clinical manifestations, identified five new mutation sites on NLRP3 and analyzed the correlation between the genotypes and phenotypes. We also raise concerns for one case
