Abstract

Titanoclinohumite, titanochondrodite, and associated Na-bearing tremolite occurring as crystal fragments in the Buell Park kimberlite are not likely crystallization products of a kimberlite magma. They more likely formed as phases in hydration assemblages of peridotite at temperatures below 700 ° C and pressures below 18 kbar. The crystals were dispersed in kimberlite as rock fragments were comminuted during transport to the surface.
