This pattern coincided with a geophysical signature related to the 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.
of further potentially diamond bearing mantle xenolith
The recovery of microdiamonds in the mantle xenolith
100 kilogram samples were collected representing the xenolith
, matrix and run of mill (ROM) portions of the outcropping diamond occurrence, previously identified and reported upon in April 2005.
subsequently confirmed as diamondiferous by the recovery

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).
