2阿尔金断裂带印支期走滑活动的地质及年代学证据显示文摘阿尔金断裂带中段出露一套花岗质和角闪质糜棱岩及糜棱岩化岩石, 初步研究表明这套岩石是左行走滑剪切过程中同构造深熔作用的产物, 是韧性转换挤压作用的结果. 同剪切深熔作用形成的花岗质和角闪质糜棱岩中, 分选出深熔成因的长柱状锆石和残余的变质成因次浑圆柱状锆石两种类型. 单颗粒锆石离子探针(SHRIMP)定年测得两组年龄, 其中461~547 Ma年龄组为次浑圆柱状残余的变质成因锆石的年龄, 另一组239~244 Ma为长柱状深熔型锆石的年龄, 这种锆石在岩石中定向排列, 其晶体长轴方向与拉伸线理方向一致, 代表走滑剪切过程中的构造应力方向. 测得同样糜棱岩样品中定向生长的角闪石的-(40)Ar--(39)Ar年龄为223~226 Ma. 以上地质学及年代学证据表明同构造深熔作用发生在印支期, 说明阿尔金断裂带至少在印支期发生了强烈的走滑运动.李海兵 杨经绥 许志琴 吴才来 万渝生 史仁灯 J.

3Adakitic rocks associated with the Shilu copper–molybdenum deposit in the Yangchun Basin,South China,and their tectonic implications显示文摘South China is famous for the extensive magmatism and polymetallic mineralization that took place there in the Mesozoic. Shilu is a large porphyry–skarn Cu–Mo deposit in the Yangchun Basin, South China. The lithology of the Shilu intrusion is granodiorite and quartz diorite, both of which are high-K calc-alkaline series, with high Sr([400 ppm) content along with low Y and Yb contents. Most of the samples have characteristics of adakite except for a few samples that have slightly higher Y and Yb contents, which may be plausibly explained by crustal contamination. Laser Ablation Inductively Coupled Plasma Mass Spectrometry zircon U–Pb dating revealed ages between 106.6 ± 1.3 and 103.9 ± 0.5 Ma, with multiple magmatic pulses. Molybdenite Re–Os isochron age of 102.2 ± 2.9 Ma(MSWD = 9.4) was determined, which is identical to the youngest zircon U–Pb age(103.9 ± 0.5 Ma) within error.The Shilu intrusion has high oxygen fugacity as indicated by high zircon Ce^(4+)/Ce^(3+) and Eu_N/Eu_N* ratios. Considering the geochemical characteristics(high Sr, and low Y and Yb contents), high oxygen fugacity, and copper mineralization of the Shilu intrusion, it was most likely formed by partial melting of a subducted young oceanic slab. Whole-rock Sr–Nd isotope-, zircon Hf isotope-, and whole-rock trace element analyses show that Shilu adakitic magmas may have interacted with type II enriched mantle and/or crustal materials during ascent. South China was affected by the Pacific tectonic regime to the east and the Neo-Tethys tectonic regime to the south in the Cretaceous. Based on the Pacific Plate drifting and rotation history, it is hard to explain how the Pacific Plate would have subducted and melted, forming adakitic rocks in the Shilu region. Considering the tectonic history of Southeast Asia and the South China Sea, the Neo-Tethys trench should have been much closer to the South China Block in the Cretaceous, and thus have had a greater impact on the South China Block. Based on the subduction direction, time of subduction,and distance between the Neo-Tethys subduction zone and the Shilu deposit, subduction of the Neo-Tethys ridge is the best mechanism for explaining the Shilu adakitic rocks and Cu–Mo mineralization.Lipeng Zhang Yongbin Hu Jinlong Liang Trevor Ireland Youliang Chen Rongqing Zhang Saijun Sun Weidong Sun 2017Acta Geochimica2017,36,2:15
4Development of the Documentation and Appraisal Review Tool for systematic reviews显示文摘AIM:To develop a tool to more explicitly assess and document the quality of systematic reviews.METHODS:We developed the Documentation and Appraisal Review Tool(DART)using epidemiologic principles of study design and the following resources:the modified Overview Quality Assessment Questionnaire(modified OQAQ),Assessment of Multiple Systematic Reviews(AMSTAR),the Cochrane Handbook,and the standards promoted by the Agency for Healthcare Research and Quality,and the Institutes of Medicine(IOM).We designed the DART tool to include the following:more detail to provide guidance and improve standardization of use,an approach to assess quality of systematic reviews addressing a variety of research designs,and additional space for recording notes to facilitate recall.DART underwent multiple rounds of testing with methodologists of varying levels of training and experience.Based on the results of six phases of pilot testing,we revised DART to improve performance,clarity and consistency.Pilot testing also included comparisons between DART,and the two most commonly used tools to evaluate the quality of systematic reviews,the modified OQAQ and AMSTAR.RESULTS:Compared to AMSTAR and modified OQAQ,DART includes two unique questions and several questions covered by modified OQAQ or AMSTAR but not both.Modified OQAQ and DART had the highest reporting consistency.Four AMSTAR questions were unclear and elicited inconsistent responses.Identifying reviewer rationale was most difficult using the modified OQAQ tool,and easiest using DART.DART allowsfor documentation of reviewer rationale,facilitating reconciliation between reviewers and documentation for future updates.DART also provides a comprehensive,systematic approach for reviewers with limited experience with systematic review methodology,to critically analyze systematic reviews.In addition,DART is the only one of the three tools to explicitly include quality review for biases specific to observational studies.This is now more widely recognized as important for assessing risk in order to generate recommendations that balance benefit to harm.The tool also includes the assessment of standards recommended by the March 2011 IOM Standards for Systematic Review.CONCLUSION:This comprehensive tool improves upon existing tools for assessing the quality of systematic reviews and guides reviewers through critically analyzing a systematic review.Rebecca L Diekemper Belinda K Ireland Liana R Merz 2015World Journal of Meta-Analysis2015,3,3:5
5Major Miocene geological events in southern Tibet and eastern Asia induced by the subduction of the Ninetyeast Ridge显示文摘Cenozoic adakitic rocks in the Gangdese changed from barren continental melts to ore-forming slab melts at * 23 Ma. The distribution and chemical characteristics of the ore-forming adakites point to an association with the Ninetyeast Ridge. The subduction of the thick,rigid Ninetyeast Ridge changed the geometry and rheology of the eastern Tibetan Plateau lithosphere and asthenosphere, restrained the eastward escape of asthenospheric mantle as well as continental fragments, and promoted the uplift and building of the Tibetan Plateau, which consequently changed the tectonic and climatic regimes in eastern Asia.Xinlei Sun Wei-dong Sun Yong-bin Hu Wei Ding Trevor Ireland Mei-zhen Zhan Ji-qiang Liu Ming-xing Ling Xing Ding Zhao-feng Zhang Wei-ming Fan 2018Acta Geochimica2018,37,3:4

9Genetic and environmental control of fruit maturation,dry matter and firmness in apple(Malus×domestica Borkh.)显示文摘For any given genotype,the environment in which an apple is grown can influence the properties of the fruit considerably.While there has been extensive research on the mechanism of the genetic control of fruit quality traits,less effort has been made to investigate the way that these genetic mechanisms interact with the environment.To address this issue,we employed a large‘Royal Gala’בBraeburn’population of 572 seedlings replicated over sites in three climatically diverse apple-growing regions in New Zealand.Phenotyping for traits including fruit maturation timing,firmness and dry matter content was performed at each of these three sites for a single growing season(2011),and at two sites(Motueka and Hawke’s Bay)for two seasons(2009 and 2010).The phenotype data collected over 2 years at two sites enabled the detection of 190 quantitative trait loci(QTL)that controlled these traits regardless of year or growing location,as well as some chromosomal loci that influenced the traits in a single given environment or year.For those loci that were environmentally stable over three sites,there was an interdependency of fruit maturation date,dry matter content and storage potential within this population,with two regions on Linkage Groups(LGs)10 and 16 strongly contributing.If these loci were used in a marker-assisted selection programme to select for progeny bearing firmer fruit,this would have the unintentional consequence of selecting,high dry matter content,later maturing apples.In addition,a further 113 new QTLs with a smaller effect were identified,some of which were exhibited only in a single growing environment,demonstrating the underlying complexity of control of traits determining fruit quality,in addition to the need for being aware of environmental effects when developing new apple varieties.David Chagne Daya Dayatilake Robert Diack Murray Oliver Hilary Ireland Amy Watson Susan E Gardiner Jason W Johnston Robert J Schaffer Stuart Tustin 2014Horticulture Research2014,1,1:2
