Oriented kokchetavite compound rods in clinopyroxene of Kokchetav ultrahigh-pressure rocks

► Oriented KAlSi3O8 rod inclusions within Cpx of two Kokchetav UHP rocks were studied. ► The majority of KAlSi3O8 rod inclusions within Cpx is kokchetavite. ► Kokchetavite is associated with Phn, Crs and other phases, forming compound rods. ► Similar kokchetavite polyphase inclusions are also present within garnet. ► Kokchetavite most likely resulted from melt/fluid-clinopyroxene interactions.
