Timing of formation of the Hongdonggou Pb-Zn polymetallic ore deposit,Henan Province,China:Evidence from Rb-Sr isotopic dating of sphalerites

引用

Geoscience Frontiers 2017年第3期8卷 605-616页

作者： Fan Yang Gongwen Wang Huawen Cao ruixi li li Tang Yufeng Huang Hao Zhang Fei Xue Wenjuan Jia Nana Guo School of Earth Sciences and Resources China University of Geosciences Beijing29 Xueyuan RoadBeijing 100083China Chengdu Center China Geological SurveyChengdu 610081China Luanchuan Bureau of Geology and Resources Luoyang 417500China

The Hongdonggou Pb-Zn polymetallic ore deposit, located in the southwestern part of the Luanchuan Mo-W-Pb-Zn-Ag polymetallic ore mineralization in Henan Province, China, is an important part of the East Qinling metallogenic belt. The orebodies in the deposit, which are vein, bedded and lenticular, are mainly hosted in the syenite porphyry, and formed within the carbonate and clastic rocks of the Yuku and Qiumugou formations partially. The genesis of the deposit has previously been argued to be of hydrothermal-vein type or of skarn-hydrothermal type. In this study, we report the results of Rb-Sr isotopic dating based on sphalerites from the main orebody of the Hongdonggou Pb-Zn polymetallic ore deposit, which yield an isochron age of 135.7 ± 3.2 Ma, constraining the timing of mineralization as early Cretaceous. The age is close to those reported for the Pb-Zn deposits in the Luanchuan ore belt. The （87Sr/86Sr）i values of the sphalerites （0.71127± 0.00010） are lower than that of terrigenous silicates （0.720） and higher than the mantle （0.707）, suggesting that the metallogenic components were mainly derived through crust-mantle mixing. Combining the results from this study with those from previous work, we propose that the Hongdonggou Pb-Zn polymetallic ore deposit is a hydrothermal-vein deposit associated with the early Cretaceous tectonothermal event, and the mineralization is controlled by NW- and near EW-trending faults in the Luanchuan Mo-W-Pb-Zn-Ag polymetallic ore concentration belt.

为了了解塔里木河上游地区荒漠植物叶片的功能性状及其对不同生境的生态适应性,以花花柴(Karelinia caspica)和骆驼刺(Alhagi sparsifolia)两种典型荒漠植物为研究对象,分析沙地和盐碱地等不同生境下两种荒漠植物叶片的结构性状和化学性状,并结合冗余分析探讨了其与土壤因子的关系。结果表明:(1)研究区花花柴、骆驼刺两种荒漠植物的叶厚度(LT)、叶面积(LA)、比叶面积(SLA)及叶组织密度(LTD)等结构性状在不同物种之间存在显著差异(P<0.05),而叶片有机碳(LOC)、氮(LN)、磷(LP)含量等化学性状在不同生境之间存在显著差异(P<0.05),其平均值分别为417.67g/kg、15.14g/kg及1.12g/kg,低于全球植物叶片平均水平。(2)在沙地和盐碱地等不同生境下两种荒漠植物叶片LA、SLA及LTD等均呈极显著负相关(P<0.01),LA和N/P是两种生境下植物叶片性状中综合排名前三的共同指标因子。(3)冗余分析结果表明,土壤因子中的土壤含水量(SWC)、土壤有机碳(SOC)和土壤氮(SN)对荒漠植物叶片性状变异起到了较好的解释。本研究表明不同荒漠植物在长期进化过程中形成了相对稳定的叶片结构性状特征,而叶片化学性状对生境土壤因子的变化则较为敏感。
