The goal was to c.mpare body mass index (BMI), waist c.rc.mferenc. (Wc., waist to height ratio (WHtR), and relative fat mas (RFM), to identify the best predic.or of overweight and obesity in university students from Mexic.. This is a c.oss-sec.ional survey with 697 university students from northern and c.ntral Mexic. (448 women, and 249 men aged 18 - 19 years). Data was c.llec.ed during 2018. Overweight and obesity were c.lc.lated from those indic.s and for both, female and male students, the order of c.rrelation between a pair of indic.s were WHtR vs. RFM > WHtR vs. Wc.> RFM vs. Wc.> WHtR vs. BMI > BMI vs. Wc.> RFM vs. BMI. It is c.nc.uded to use the WHtR and the RFM to better predic. overweight and obesity in young Mexic.n university students.

浅成低温热液矿床是世界上银矿的重要矿床类型,伴生有金铜铅锌等多种金属。银的赋存状态研究可以为矿床资源禀赋、选冶成本以及经济价值的综合评价提供重要的依据。近年来,矿物自动定量分析系统越来越多地应用到贵金属的赋存状态研究中,相比传统方法而言其能提供精确定量的矿物学信息。悦洋银多金属矿床位于福建省紫金山矿田,是典型的浅成低温热液矿床,是研究银赋存状态的理想选区。通过野外地质调查研究发现,矿体主要受控于岩性边界和断裂构造,主要矿石类型为热液角砾岩型和石英脉型。成矿作用可以分为石英-黄铁矿、石英-黄铁矿-黄铜矿、石英-银多金属、石英-碳酸盐等四个阶段,其中银在石英-银多金属阶段沉淀,可以进一步划分为石英伊利石硫化物亚阶段和石英冰长石硫化物亚阶段。本文在野外地质调查的基础上,针对不同的矿石类型使用TIMA(TESc.N Integrated Mineral Analyzer)自动矿物分析系统,结合显微镜下观察、扫描电镜和电子探针分析手段,对银的赋存形式和分布情况进行了定量化研究,根据矿物共生组合对银沉淀机制及成矿过程进行了探讨。研究结果显示,悦洋矿床中的银90%以上以独立矿物的形式存在,主要是硫化银和自然银,且粒径大多在10~50μm之间;少部分银以次显微包裹体形式存在于黄铜矿中,或以显微包裹体和类质同相形式存在于黄铁矿和闪锌矿中。成矿热液中银主要以硫氢络合物形式运移,主成矿期大量的冰长石与银矿物共生表明沸腾作用是主要的沉淀机制。
