1Protoliths of enigmatic Archaean gneisses established from zircon inclusion studies:Case study of the Caozhuang quartzite,E.Hebei,China显示文摘A diverse suite of Archaean gneisses at Huangbaiyu village in the North China Craton,includes rare fuchsite-bearing(Cr-muscovite) siliceous rocks- known as the Caozhuang quartzite.The Caozhuang quartzite is strongly deformed and locally mylonitic,with silica penetration and pegmatite veining common.It contains abundant 3880-3600 Ma and some Palaeoarchaean zircons.Because of its siliceous nature,the presence of fuchsite and its complex zircon age distribution,it has until now been accepted as a(mature) quartzite.However,the Caozhuang quartzite sample studied here is feldspathic.The shape and cathodoluminescence petrography of the Caozhuang quartzite zircons show they resemble those found in immature detrital sedimentary rocks of local provenance or in Eoarchaean polyphase orthogneisses,and not those in mature quartzites.The Caozhuang quartzite intra-zircon mineral inclusions are dominated by quartz,with lesser biotite,apatite(7%) and alkali-feldspar,and most inclusions are morphologically simple.A Neoarchaean orthogneiss from near Huangbaiyu displays morphologically simple inclusions with much more apatite(73%),as is typical for fresh calc-alkaline granitoids elsewhere.Zircons were also examined from a mature conglomerate quartzite clast and an immature feldspathic sandstone of the overlying weakly metamorphosed Mesoproterozoic Changcheng System.These zircons have oscillatory zoning,showing they were sourced from igneous rocks.The quartzite clast zircons contain only rare apatite inclusions(<1%),with domains with apatite habit now occupied by intergrowths of muscovite + quartz ± Fe-oxides ± baddeleyite.We interpret that these were once voids after apatite inclusions that had dissolved during Mesoproterozoic weathering,which were then filled with clays ± silica and then weakly metamorphosed.Zircons in the immature feldspathic sandstone show a greater amount of preserved apatite(11%),but with petrographic evidence of replacement of other apatites by quartz and mica.From the zircon morphology and inclusions studies,our studied Caozhuang quartzite is most likely <3500 Ma immature detrital sedimentary rock of local provenance.This strengthens the case for Eoarchaean rocks with a substantial 3880-3800 Ma component occur close to Huangbaiyu.Allen P.Nutman Ronni Maciejowski Yusheng Wan 2014Geoscience Frontiers2014,5,4:7

7Analysis of Oxides Formed on the Surface of the Alloy 690 in Hydrogenated Supercritical Water显示文摘The oxides formed on the surface of the alloy 690 in hydrogenated supercritical water at 400℃ for 1000 h were investigated using scanning electron microscopy,transmission electron microscopy,scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy.The oxides on me surface of the alloy 690 exhibited multi-layer structure:an outer layer consisted of granular crystallites(NiO and NiFe_2O_4) and a compact inner layer(spinel and Cr_2O_3).Chemical analysis indicated that the outer layer was enriched in nickel but depleted in chromium,whereas the inner layer was enriched in chromium and iron but depleted in nickel.The inner layer was also characterized as layered structure by Fe-rich spinel on top of continuous Cr_2O_3 layer.Besides,Cr_2O_3 nodules were readily observed at the oxides/alloy interface.Jin Gao Fa-rong Wan Guo-ping Cao Kumar Sridharan Todd Allen 2016Acta Metallurgica Sinica(English Letters)2016,29,8:0

10中国储户转战股市显示文摘中国的普通投资者都企盼股市能有所起色。但如果他们不持谨慎态度的话,情况也许会适得其反。 尽管今年上证综合指数的跌幅已超过21%,但27岁的潘伟婷(Pan Weiting,音译)依然还是看不到股市以外其他更好的投资渠道。最近,房价攀升到了创纪录的新高,在上海任会计的潘伟婷将买房计划搁置了下来。她存在银行里的40万元人民币(约合5.9万美元)每年只有2.25%的利息,Chua Kong Ho Zhang Shidong Allen Wan 夏芳(译) 2010商业周刊(中文版)2010,,7:0
11躺平风潮蔓延全球显示文摘在世界各地,太多人正在重新思考他们的工作和生活方式一一以及如何平衡两者。“大辞职”现象下,辞去工作不干的美国打工族数量正创下历史纪录——2021年4月至9月期间,超过2400万人这样做了,而且许多人正停留在劳动力市场之外。德国、日本和其他富裕国家也出现了同样的趋势。首先是疫情的原因。调查显示,在许多国家,人们的倦总感增加,心理健康状况恶化。这种压力从几十年前就开始积累。收入停滞不前,工作上的安全感风雨飘摇,住房和教育成本升,这一切都使得能够过上稳定经济生活的年轻人越来越少。Tom Hancock Katia Dmitrieva Carolynn Look Yuko Takeo Allen Wan Amanda Wang 永年(译) 2022复印报刊资料(人力资源开发与管理)2022,,4:0
12能卖掉一切的带货女主播显示文摘忘掉威利·洛曼或《欢乐音乐妙无穷》(The Music Man)里的哈罗德·希尔(Harold Hill)教授吧。中国的直播带货女王黄薇真的能卖得掉任何商品。举例来说,今年4月份,网名薇娅的黄薇以4000万元人民币的价格卖掉了一次火箭运载服务。而比起她在2019年“光棍节”的业绩,这根本算不上什么;“光棍节”是去年中国最大的一次购物活动,那一天,薇娅引导成交销售额超过30亿元人民币。这个数字比帕劳以及圣多美和普林西比等国家的国内生产总值还要高。Jinshan Hong Chunying Zhang Allen Wan Janet Paskin 晓立(译) 2020商业周刊(中文版)2020,,10:0
