Strontium Isotope Analysis of Kimberlitic Groundmass Perovskite via LA‐MC‐ICP‐MS

Geostandards and Geoanalytical Research, 2007
Strontium isotopic composition is a potentially powerful tracer in studies of kimberlitic rocks but the results from even the most carefully collected and stringently prepared bulk‐rock samples are still hampered by contamination and alteration effects.
