Short summary
Cassiterite is the primary tin ore mineral and is associated with other elements needed for green technology. The mineral is deposited from hydrothermal fluids released from magmas. Because it is extremely acid resistant, there has been difficulty dissolving the mineral for isotopic analysis. To improve the understanding of the timing and models of formation processes, we use a novel method to dissolve and extract radiogenic isotopes of the uranium-to-lead decay scheme from cassiterite.
