This pattern coincided with a geophysical signature related to the xenolith package.
mantle xenolith at Seitapera near Kuhmo was confirmed as diamondiferous
Each sample was slabbed to approximately one centimeter in thickness, and any visible weathering rind and/or xenolith material was trimmed away.
Objectives of this study include: 1) determining mineral composition of olivine, clinopyroxene, and orthopyroxene in the xenoliths; 2) examining individual chemical zoning characteristics or orthopyroxene, clinopyroxene, and olivine; 3) comparing mineral chemistry and zoning differences between xenoliths from different eruption styles; and 4) use xenolith compositions to determine lithospheric mantle pressure and temperature.
Recent prospecting and stripping programs on the Cobalt Property have resulted in the mapping of a number of xenolith bearing hypabbysal dyke intrusions in the Pan-Anderson Lake area.
This report presents and discusses the potential beneficiation (crushing and separating rock into valuable substances or waste by any of a variety of techniques) of the diamond bearing xenolith from the matrix that hosts the xenolith in a particular diamond occurrence located on the joint venture's 45 square kilometer property situated 35 km.

Corona-type aggregates that formed on xenolith margins may be analogous to pegmatoidal "strain shadows" reported in some granitoids, which formed through the flow of intercumulus melt into low-pressure areas generated by the rotation of xenoliths during late-magmatic deformation (Paterson and Miller 1998).
