黑龙江多宝山斑岩铜矿主要赋存于奥陶纪花岗闪长岩中,少量发育于奥陶纪花岗闪长斑岩及奥陶系多宝山组安山岩中,铜矿化以浸染状、细脉-浸染状为主。成矿过程经历了斑岩期、剪切变形期。矿区发育韧性剪切变形带,多宝山组、花岗闪长岩、花岗闪长斑岩、安山质凝灰角砾岩及矿体均发生了剪切变形作用,沿剪切面发育绢云母新生矿物。绢云母的坪年龄和正反等时线年龄分别为280.1±1.2 ma和281.4±1.3 ma、281.3±1.3 ma,在误差范围内基本一致,限定矿区韧性剪切变形的时间为早二叠世(约280 ma)。多宝山斑岩铜矿床主要成矿作用形成于斑岩期,成矿时代为早奥陶世(约475 ma),早二叠世的韧性剪切变形作用对原生斑岩铜矿化进行了改造,使矿石的铜进一步富集,品位相对增高。

Transition metal oxide is a promising candidate for future supercapacitors due to its pronounced electrical properties and low cost.Unfortunately,the poor cycle stability and low capacitance due to the small lattice spacing and strong volume expansion in dense transition metal oxide impede its practical applications seriously.Herein,a nanoporous electrode of metal oxide has been prepared via the solvothermal and subsequent calcination process of MOF-74(MOF=metal-organic framework),which shows outstanding cycle reversibility,excellent capacitance.Because of large surface areas with a nanoporous structure which is beneficial to the ion transport and relief to volume expansion.Three samples with different divalent metals(MOF-74-Ni,MOF-74-NiCo2 and MOF-74-Co)were prepared by hydrothermal method.After a facile annealing process,the NiO,NiCo2O4 and Co3O4 with the large surface area and porous structure were easily obtained and further the electrochemical properties were investigated.As a result,the NiCo2O4 electrode exhibits obviously high specific capacity(684 F/g)and excellent cycling stability(86%retention after 3000 cycles)compared with the monometallic oxides.

The Northern Hemisphere(NH)often experiences frequent cold air outbreaks and heavy snowfalls during La Nina winters.In 2022,a third-year La Nina event has exceeded both the oceanic and atmospheric thresholds since spring and is predicted to reach its mature phase in December 2022.Under such a significant global climate signal,whether the Eurasian Continent will experience a tough cold winter should not be assumed,despite the direct influence of mid-to high-latitude,large-scale atmospheric circulations upon frequent Eurasian cold extremes,whose teleconnection physically operates by favoring Arctic air invasions into Eurasia as a consequence of the reduction of the meridional background temperature gradient in the NH.In the 2022/23 winter,as indicated by the seasonal predictions from various climate models and statistical approaches developed at the Institute of Atmospheric Physics,abnormal warming will very likely cover most parts of Europe under the control of the North Atlantic Oscillation and the anomalous anticyclone near the Ural Mountains,despite the cooling effects of La Nina.At the same time,the possibility of frequent cold conditions in mid-latitude Asia is also recognized for this upcoming winter,in accordance with the tendency for cold air invasions to be triggered by the synergistic effect of a warm Arctic and a cold tropical Pacific on the hemispheric scale.However,how the future climate will evolve in the 2022/23 winter is still subject to some uncertainty,mostly in terms of unpredictable internal atmospheric variability.Consequently,the status of the mid-to high-latitude atmospheric circulation should be timely updated by medium-term numerical weather forecasts and sub-seasonal-to-seasonal prediction for the necessary date information and early warnings.

TheWulong lode deposit contains over 80 tonnes of gold with an average grade of 5.35 g/t.It is one of the largest deposits in Dandong City,Liaoning Province in northeast China.Previous studies on the deposit focused on its geological characteristics,geochemistry,fluid inclusions,and the timing of gold mineralization.However,controversy remains regarding the origin of the ore-forming fluids and metals,and the genesis of the gold deposit.This paper presents zircon UePb and pyrite RbeSr ages and S,Pb,He,and Ar isotopic results along with quartz H and O isotopic data for all litho-units associated with the deposit.Laser ablation inductively coupled mass spectrometry measurements yielded zircon UePb dates for samples of pre-mineralization rocks like granite porphyry dike,the Sanguliu granodiorite,fine-grained diorite,and syn-mineralization diorite,as well as post-mineralization dolerite,and lamprophyre;their emplacement ages are 1261 ma,1241 ma,1231 ma,1201 ma,1192 ma,and 1152 ma,respectively.The pyrite RbeSr isochron age is 1191 ma,indicating that both magmatism and mineralization occurred during the Early Cretaceous.The d18OH2O values of ore-forming hydrothermal fluids from the quartzepolymetallic sulfide vein stage vary from 4.8&to 6.5&,and the dDV-SMOW values are between67.7&and75.9&,indicating that the ore-forming fluids were primarily magmatic.The noble gas isotope compositions of fluid inclusions hosted in pyrite suggest that the ore-forming fluids were dominantly derived from crustal sources with minor mantle input.Sulfur isotopic values of pyrite vary between 0.2&and 3.5&,suggesting that S was derived from a homogeneous magmatic source or possibly from fluids derived from the crust.The Pb isotopic compositions of sulfides(207Pb/204Pb?15.51 e15.71,206Pb/204Pb?17.35e18.75,208Pb/204Pb?38.27e40.03)indicate that the Pb of the Wulong gold deposit is a mixture of crust and mantle components.Geochronological and geochemical data,together with the regional geological history,indicate that Early Cretaceous mag

植被物候是表征生态系统对气候变化响应的重要指标。草地枯黄期是研究陆地生态系统对气候变化响应的重要指标,然而,植被枯黄期研究较少,寻找适合提取当地的植被枯黄期的最佳模型显得尤为重要。本研究采用双逻辑斯蒂函数拟合法(D-L)、非对称性高斯函数拟合法(A-G)、Savitzky-Golay滤波法(S-G)3种方法分别模拟了2001-2019年新疆地区草地枯黄期,对比草地枯黄期不同物候提取方法,确定新疆地区草地枯黄期的最佳遥感提取方法,并对草地枯黄期空间格局及变化趋势进行分析。结果表明:1)双逻辑斯蒂函数拟合法是提取新疆地区枯黄期的最佳方法。2)3种方法估算的新疆地区草地枯黄期均呈现自北向南逐渐提前的明显地域差异。3)3种遥感方法估算的草地枯黄期均呈现提前的趋势,显著提前(P<0.1)的区域分布于阿尔泰山以南、准噶尔盆地中部及西部边缘区。4)不同草地类型下,利用A-G和D-L两种方法提取的草地枯黄期年际变化趋势基本保持一致。
