科技查新服务在地质调查工作中的作用

我国地质科技查新工作始于20世纪90年代,由地质矿产部情报研究所承担。近年来,国土资源部地学科技查新站为国土资源系统、地勘行业单位以及地学院校等单位的科研立项、成果报奖、职称评定、博硕士毕业等提供了大量支撑。该文在总结国土资源部地学科技查新站发展现状的基础上,从查新课题角度出发,分析了科技查新在地质调查工作中的作用。

高温熔融研制安山岩玻璃标准物质初探

地质标准玻璃物质在激光剥蚀等离子体质谱技术应用中发挥着重要的作用,目前国内对于地质标准玻璃物质合成方法研究还较少,一定程度上限制了该技术的高精度应用。本文对国家一级安山岩粉末标准物质(GSR-2)采用高温熔融法合成安山岩玻璃标准物质(GSR-2G),探讨了熔融温度、时间、淬火方式对安山岩玻璃均一性的影响。实验确定了在熔融温度1300℃、熔融时间4 h的最佳条件下,采用液氮淬火合成的安山岩玻璃标准物质GSR-2G均一性较好,可作为微区分析的内部标准物质。利用193 nm ArF准分子激光剥蚀-四极杆等离子体质谱(LA-Q-ICPMS)分析合成的GSR-2G中35个微量元素和10个主量元素,精密度(RSD)均优于10%。GSR-2G的7Li～238U共35个微量元素,化学法分析测定值与LA-Q-ICPMS测定值的相对偏差优于10%;23Na～56Fe共10个主量元素,电子探针分析测定值与LA-Q-ICPMS测定值一致。利用LA-Q-ICPMS法分析GSR-2G中40个元素,获得的平均测定值可作为初步参考值。
