Summary

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, in press). 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 [...]

Purpose

The data were obtained to demonstrate a practical application of the LA-ICPMS analytical procedure for U–Pb dating of cassiterite (SnO2) without reliance on an independently dated matrix-matched cassiterite reference material that was characterized by other (“higher precision”) technique such as ID-TIMS. The area chosen for this study was the Cornwall and Devon regions of southwest England where known ages of the host granitic rock (Cornubian Batholith) could be compared to the newly acquired cassiterite ages.
