The lowermost 345 m comprises countless thin layers and wisps, commonly no
more than a few mm thick, of dunite, poikilitic and granular harzburgite, olivine
pyroxenite and feldspathic pyroxenite. Rarely, individual layers reach up to 40 m.

Nevertheless, the sNd values in the rocks under study indicate that the pyroxenite
and gabbro-pegmatite are not comagmatic with dunite, chromitite and olivine
pyroxenite. This implies, that there are three types of rocks in the Render
intrusion ...
