Abstract Boron is a quintessential crustal element but its conspicuous presence in diamond – a mantle mineral – raises questions about potential subduction pathways for boron and other volatiles. It has been a long-standing goal to characterize the isotopic composition of boron in blue,...

Download2017-02-01
E. Jackson, Simon E., Bussweiler, Yannick, Hardman, Matthew, Stern, Richard A., Brey, Gerhard Peter, Kjarsgaard, B.A., Pearson, Graham, Stachel, Thomas
This study provides an experimental calibration of the empirical Al-in-olivine thermometer for mantle peridotites proposed by De Hoog et al. (2010). We report Al concentrations measured by secondary ion mass spectrometry (SIMS) in olivines produced in the original high-pressure, high-temperature,...

The evolution of calcite-bearing kimberlites by melt-rock reaction: evidence from polymineralic inclusions within clinopyroxene and garnet megacrysts from Lac de Gras kimberlites, Canada

Luth, R. W., Stone, Rebecca, Menzies, Andrew, Bussweiler, Yannick, Pearson, Graham, Stachel, Thomas, Kjarsgaard, B. A.
Megacrystic (>1 cm) clinopyroxene (Cr-diopside) and garnet (Cr-pyrope) xenocrysts within kimberlites from Lac de Gras (Northwest Territories, Canada) contain fully crystallized melt inclusions. These ‘polymineralic inclusions’ have previously been interpreted to form by necking down of melts at...
