Abstract:
Here, we present new Sr-Nd-Hf isotopic, major, and trace element compositions for 61 fresh lamproite samples with ages ranging between 2 Ga and the Quaternary, and compare these results with existing data for cratonic lamproites worldwide. We then use the combined data-set to re-evaluate the origin of cratonic lamproites on a global scale.
