  author={M. Hodgson and A. Dudeney},
Olivine and serpentine in kimberlite from the Wesselton pipe have been quantitatively determined by a modified X-ray diffraction procedure in which concentrates of the minerals were separated from the kimberlite for use as analytical standards. The olivine extracted was essentially mono-mineralic but the serpentine contained 25% olivine as finely disseminated inclusions. Equations were deduced to interrelate measured X-ray diffraction intensities with the mineral content and particle size… Expand
