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...
CA-ID-TIMSWilyerpa FormationArticleA central prediction of the Snowball Earth hypothesis is that glacial onset should be synchronous at low latitudes, and its termination should be rapid and synchronous globally. High precision U/Pb zircon ages provide supporting evidence for the synchronous onset (...

New U–Pb CA-ID-TIMS geochronology Meaningful paleobiologic analyses of fauna associated with the zenith of dinosaur diversity in the Campanian requires a set of internally consistent radioisotopic ages of wide geographic distribution upon which high resolution chronostratigraphic frameworks can be construct...
The sample matrix must be separated before ID-TIMS measurements, which is a slow and tedious process that hindered the adoption of the technique in routine clinical measurements. We have developed a fast and accurate method for the determination of Ca, Mg, and K in serum by taking advantage ...
