Summary

Cassiterite (SnO2) samples were collected from alluvial ore concentrate from the Abu Dabbab Granite in eastern Egypt. Samples (in the form of mounted loose grains) 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 2019. This data release accompanies the publication, 'Monazite and cassiterite U-Pb dating of the Abu Dabbab rare-metal granite, Egypt: Late Cryogenian metalliferous granite magmatism in the Arabian-Nubian Shield.' (Lehmann and others, 2020). The publication constrains the timing of the magmatic-hydrothermal processes of the Abu Dabbab Granite which represents the oldest, highly-evolved [...]

Purpose

The data were obtained to further demonstrate the 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") techniques such as ID-TIMS. The area chosen for this study was the Abu Dabbab Granite. Here, the cassiterite geochronology dataset, along with further geochronology of columbite-tantalite and monazite and other geological information, will provide the framework to elucidate the time-space evolution of the Abu Dabbab magmatic and hydrothermal systems.
