DOI: 10.1134/s1028334x19110242
Abstract: Olivine (high-Fe forsterite; Fo# 69-76) and associated minerals have been studied in a coesite-bearing diamondiferous eclogite from the Udachnaya-East kimberlite pipe. Olivine was identified in the rock interstices together with K-feldspar, sodalite, phlogopite, and djerfisherite.… read more here.

DOI: 10.1139/cjes-2017-0019
Abstract: We use analogue experimentation to test the hypothesis that host rock competence primarily determines the morphology of kimberlite pipes, which are subdivided into three classes: Class 1 pipes are steep-sided diatremes emplaced into crystalline rock;… read more here.
