1黑龙江省嫩江-黑河构造混杂岩带科洛金矿床成因:来自黄铁矿化学成分及He-Ar、S、Pb同位素证据显示文摘科洛金矿床位于黑龙江省嫩江—黑河构造混杂岩带中,为一正在勘查的中型金矿床。前人研究认为该矿床为一中温、富水、低盐度的韧性剪切带型金矿床。但随着勘查工作的持续开展,新发现了大量含多金属硫化物的石英脉型矿石。为进一步明确该矿床成因,对科洛金矿床内韧性变形和浸染状-团块状两种不同产状黄铁矿进行了系统的成分标型及稳定同位素特征研究。结果表明:韧性变形黄铁矿较浸染-团块状黄铁矿的S/Fe值低,Au、Ag、Co含量高,As含量低,总体显示韧性变形黄铁矿相对贫硫;黄铁矿微量元素显示两类黄铁矿REE具有相似的地球化学特征,整体呈轻稀土富集、重稀土亏损的'右倾'式稀土配分模式。稀土元素总量为17.00×10^-6~66.95×10^-6,韧性变形黄铁矿含量明显偏低,LREE/HREE值为5.25~12.50,相对较稳定。Y/Ho值与地幔和地壳重合范围较多,Zr/Hf值、Nb/Ta值变化范围较大,显示成矿环境不稳定;黄铁矿^3He含量为2.405×10^-13~10.811×10^-13,^4He含量为3.35×10^-7~4.99×10^-7,^3He-^4He图和R/Ra-40Ar/36Ar图显示成矿流体有以地幔为主的壳幔混源特征,成矿过程应有大气降水的参与;黄铁矿δ^34S变化范围小,集中在+2.3‰^+7.6‰(韧性变形黄铁矿δ^34S平均值偏低),稍正向偏离陨石硫特征;黄铁矿的^206Pb/^204Pb=18.157~18.211;^207Pb/^204Pb=15.542~15.594;^208Pb/^204Pb=38.032~38.218(韧性变形黄铁矿的^206Pb/^204Pb、^207Pb/^204Pb、^208Pb/^204Pb平均值偏低),均显示与造山作用关系密切。利用黄铁矿化学成分特征元素Co/Ni值及Co-Ni成因判别图解认为科洛金矿有热液成因矿床特征;利用w(Fe+S)-w(As)图解和Co-Ni-As含量图解显示石英脉型矿石反映浅成低温热液型金矿特征。综合区域变质变形事件、典型矿床特征及矿区内已取得的年龄、流体包裹体等相关数据认为,科洛金矿床应存在两期矿化:三叠纪形成的韧性剪切带型金矿床和白垩纪形成的浅成低温热液型金矿床。建议在今后的矿产勘查中注意寻找真正的韧性剪切带型金矿。李成禄 李胜荣 袁茂文 杜兵盈 李文龙 Masroor ALAM 刘东园 刘浩 2020地学前缘2020,27,5:11
2NS1 antigen: A new beam of light in the early diagnosis of dengue infection显示文摘Objective: To evaluate NS1 antigen detection ELISA for the early laboratory diagnosis of dengue virus infection. Methods: The present study was conducted to evaluate the overall positivity of NS1 antigen detection ELISA and its comparison with viral RNA detection via real time PCR and Ig M antibodies detection by ELISA. Results: A total of 1 270 serum samples were tested 86%(1 097/1 270) were detected positive by one or more than one diagnostic test. Out of 1 270, 64%(807/1 270) were positive by NS1 ELISA and 52%(662/1 270), 51%(646/1 270) were positive by real-time RT-PCR and Ig M ELISA respectively.Conclusions: NS1 antigen detection ELISA is highly suitable diagnostic tools and it also has great value for use in outbreak and epidemic situation.Muhammad Suleman Rani Faryal Muhammad Masroor Alam Salmaan Sharif Shahzad Shaukat Uzma Bashir Aamir Adnan Khurshid Mehar Angez Massab Umair Mian Muhammad Sufian Yasir Arshad Ghulam Mujtaba Syed Sohail Zahoor Zaidi 2016Asian Pacific Journal of Tropical Medicine2016,9,12:6
3Environmental Suitability and Distribution of the Caucasian Rock Agama,Paralaudakia caucasia (Sauria:Agamidae) in Western and Central Asia显示文摘Predictive potential distribution modeling is crucial in outlining habitat usage and establishing conservation management priorities.In this paper we provide detailed data on the distribution of the Caucasian rock agama Paralaudakia caucasia,and use species distribution models(MAXENT) to evaluate environmental suitability and potential distribution at a broad spatial scale.Locality data on the distribution of P.caucasia have been gathered over nearly its entire range by various authors from f ield surveys.The distribution model of P.caucasia showed good performance(AUC=0.887),and predicted high suitability in regions mainly located in Tajikistan,north Pakistan,Afghanistan,southeast Turkmenistan,northeast Iran along the Elburz mountains,Transcaucasus(Azerbajan,Armenia,Georgia),northeastern Turkey and northward along the Caspian Sea coast in Daghestan,Russia.The identifi cation of suitable areas for this species will help to assess conservation status of the species,and to set up management programs.Seyyed Saeed HOSSEINIAN YOUSEFKHANI Gentile Francesco FICETOLA Nasrullah RASTEGAR-POUYANI Natalia B ANANJEVA Eskandar RASTEGAR-POUYANI Rafaqat MASROOR 2013Asian Herpetological Research2013,4,3:4
4Analysing the relationship between drought and soil erosion using vegetation health index and RUSLE models in Godavari middle sub-basin,India显示文摘Drought is a natural phenomenon posing severe implications for soil,groundwater and agricultural yield.It has been recognized as one of the most pervasive global change drivers to affect the soil.Soil being a weakly renewable resource takes a long time to form,but it takes no time to degrade.However,the response of soil to drought conditions as soil loss is not manifested in the existing literature.Thus,this study makes a concerted effort to analyze the relationship between drought conditions and soil erosion in the middle sub-basin of the Godavari River in India.MODIS remote sensing data was utilized for driving drought indices during 2000-2019.Firstly,we constricted Temperature condition index(TCI)and Vegetation Condition Index(VCI)from Land Surface Temperature(LST)and Enhanced Vegetation Index(EVI)derived from MODIS data.TCI and VCI were then integrated to determine the Vegetation Health Index(VHI).Revised Universal Soil Loss Equation(RUSLE)was utilized for estimating soil loss.The relationship between drought condition and vegetation was ascertained using the Pearson correlation.Most of the northern and southern watersheds experienced severe drought condition in the sub-basin during2000-2019.The mean frequency of the drought occurrence was 7.95 months.The average soil erosion in the sub-basin was estimated to be 9.88 t ha^(-1)year^(-1).A positive relationship was observed between drought indices and soil erosion values(r value being 0.35).However,wide variations were observed in the distribution of spatial correlation.Among various factors,the slope length and steepness were found to be the main drivers of soil erosion in the sub-basin.Thus,the study calls for policy measures to lessen the impact of drought and soil erosion.Md Masroor Haroon Sajjad Sufia Rehman Roshani Singh Md Hibjur Rahaman Mehebub Sahana Raihan Ahmed Ram Avtar 2022Geoscience Frontiers2022,13,2:4
5Petrography and geochemistry of Jumara Dome sediments, Kachchh Basin: Implications for provenance, tectonic setting and weathering intensity显示文摘In the Kachchh Mainland, the Jumara Dome mixed carbonate-siliciclastic succession is represented by the Jhurio and Patcham formations and siliciclastic-dominating Chari Formation(Bathonian to Oxfordian). The Jumara Dome sediments were deposited during sea-level fluctuating, and were interrupted by storms in the shallow marine environment. The sandstones are generally medium-grained, moderately sorted, subangular to subrounded and of low sphericity. The sandstones are mineralogically mature and mainly composed of quartzarenite and subarkose. The plots of petrofacies in the Qt-F-L, Qm-F-Lt, Qp-Lv-Ls and Qm-P-K ternary diagrams suggest mainly the basement uplift source(craton interior) in rifted continental margin basin setting. The sandstones were cemented by carbonate, iron oxide and silica overgrowth. The Chemical Index of Alteration values(73% sandstone and 81% shale) indicate high weathering conditions in the source area. Overall study suggests that such strong chemical weathering conditions are of unconformity with worldwide humid and warm climates during the Jurassic period. Positive correlations between Al2O3 and Fe2O3, TiO2, Na2O, MgO, K2O are evident. A high correlation coefficient between Al2O3 and K2O in shale samples suggests that clay minerals control the major oxides. The analogous contents of Si, Al, Ti, LREE and TTE in the shale to PAAS with slightly depleted values of other elements ascribe a PAAS like source(granitic gneiss and minor mafics) to the present study. The petrographic and geochemical data strongly suggest that the studied sandstones/shales were deposited on a passive margin of the stable intracratonic basin.Ahmad A.H.M Noufal K.N Masroor Alam M Tavheed Khan 2014Chinese Journal Of Geochemistry2014,33,1:3
6Distribution and Environmental Suitability of the Smallscaled Rock Agama, Paralaudakia microlepis(Sauria: Agamidae) in the Iranian Plateau显示文摘Predictive potential distribution modeling is of increasing importance in modern herpetological studies and determination of environmental and conservation priorities. In this article we provided results of analysis and forecasts of the potential distribution of smallscaled rock agama Paralaudakia microlepis(Blanford, 1874) using the distribution models through Maxent(www.cs.princeton.edu/ ~ schapire / maxent). We made an attempt for comparison of input of bioclimatic factors and characteristics of biotope distribution for three species of genus Paralaudakia. Constructed model identified dissemination of Paralaudakia microlepis enough performance(AUC = 0.972 with dispersion 0.003). According to the map constructed, the most suitable habitats of smallscaled rock agama Paralaudakia microlepis are located in southern and eastern Iran, the west of central Pakistan and southeastern Afghanistan.Natalia B.ANANJEVA Evgeny A.GOLYNSKY Seyyed Saeed HOSSEINIAN YOUSEFKHANI Rafaqat MASROOR 2014Asian Herpetological Research2014,5,3:3
