简介:化学溶蚀热电离质谱法(CA-ID-TIMS)是单颗粒锆石U-Pb年代学上的重大突破,是目前国际上锆石年代学高精度定年的首选,也使得我们可以深入研究地史时期重大地质事件的过程和速率。聚焦“层圈相互作用”,我们将“火山作用”作为联系地球内...
About a dozen U–Pb zircon dates have previously been reported from the Campanian of the WIB (Supplementary TableS1) and all but two are microbeam U–Pb analyses of detrital zircons59,91. The only two published CA-ID-TIMS bentonite ages were from the lower portion of the Kaiparowits Fm. ...
ID-TIMS U-Pb年龄测定结果表明大西山剖面含重要化石地层的年龄在160.89 Ma至160.25 Ma之间,属于晚侏罗纪早期牛津阶。该研究成果为目前发现的最古老带羽毛恐龙和真兽类哺乳动物的生存年代提供了确凿的高精度同位素年代学证据。 著录项 来源 《2016中国地球科学联合学术年会》||2295-2297|共3页 会议地点 北京 ...

The chronostratigraphic framework of the Sydney, Gunnedah and Bowen basins using CA-IDTIMS geochronology is enhancing correlation of stratigraphic units and providing a better understanding of local and regional sedimentation patterns. Ages range from 271.45 Ma (Rowan Formation) to 247.71 Ma (Garie For...
U–Pb geochronology using isotope dilution-thermal ionization mass spectrometry (ID-TIMS) is by far the most precise analytical technique. It affords the opportunity to determine 206Pb/238U dates with unprecedented precision often <1‰ on single analyses or weighted mean dates derived from multiple ...
