The timing of a diamondiferous kimberlite cluster within the Archean Superior Province, the Renard cluster (Otish field, Québec), was investigated by ID-TIMS U-Pb dating of groundmass perovskite. Few Otish field kimberlites were previously dated by U-Pb perovskite (Renard 1-3 and Lac Beaver) but...

Improving the use of eclogitic garnet as a diamond indicator mineral, and constraining the origin of eclogites in the subcontinental lithospheric mantle
DownloadSpring 2020
Diamond occurs in the subcontinental lithospheric mantle (SCLM) and is transported to the surface by kimberlite-lamproite volcanism and other deeply-derived volcanic rocks. In the SCLM diamond is often hosted by peridotitic or eclogitic substrates. Even when it occurs in economic abundances in a...

The Pikoo kimberlites of east-central Saskatchewan are a relatively recent discovery, comprising at least ten discreet bodies thought to erupt through the Sask Craton, a small Archean microcontinent enclosed within the Paleoproterozoic Trans-Hudson Orogen. Since the Sask Craton also plays host...
