Djerfisherite in xenoliths of sheared peridotite in the Udachnaya-East pipe (Yakutia): origin and relationship with kimberlitic magmatism
IS Sharygin, AV Golovin, NP Pokhilenko - Russian Geology and …, 2012 - Elsevier
Djerfisherite, a Cl-bearing potassium sulfide (K6Na (Fe, Ni, Cu) 24S26Cl), is a widespread
accessory mineral in kimberlite-hosted mantle xenoliths. Nevertheless, the origin of this
sulfide in nodules remains disputable. It is usually attributed to the replacement of primary
Fe–Ni–Cu sulfides when xenoliths interact with a K-and Cl-enriched hypothetical melt/fluid.
The paper is devoted to a detailed study of the composition and morphology of djerfisherite
from a representative collection (22 samples) of the deepest mantle xenoliths—sheared …
