U-Pb data for: U-Pb geochronology of tin deposits associated with the Cornubian Batholith of southwest England: Direct dating of cassiterite by in situ LA-ICPMS

Cassiterite (SnO2) samples were collected throughout Devon and Cornwall Counties in southwest England, United Kingdom. Samples were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICPMS) system at the U.S. Geological Survey in Denver, Colorado in February and April 2018. This data release accompanies the publication, 'U-Pb geochronology of tin deposits associated with the Cornubian Batholith of southwest England: Direct dating of cassiterite by in situ LA-ICPMS' (Moscati and Neymark, 2018). The publication describes a greater chronologic control and refinement of Cornubian tin ore deposition and allows comparison of its timing with previously published ages for the granitic intrusions that host the cassiterite.

锡石（Cassiterite，SnO₂）样本采集自英国英格兰西南部的德文郡与康沃尔郡全域。2018年2月及4月，研究人员于美国科罗拉多州丹佛市的美国地质调查局，使用激光剥蚀电感耦合等离子体质谱仪（Laser Ablation Inductively Coupled Plasma Mass Spectrometer，LA-ICPMS）系统完成样本制备与直接定年分析。本数据集发布配套于论文《英国西南部康沃尔岩基（Cornubian Batholith）相关锡矿床的U-Pb年代学：基于原位LA-ICPMS直接定年锡石》（Moscati与Neymark，2018）。该论文详述了康沃尔锡矿成矿作用的年代学约束与精细化厘定，并可将其成矿时序与此前已发表的赋存锡石的花岗岩侵入体年代进行对比分析。
