WEST GREENLAND GEOTHERM CALCULATION
|
The chart below demonstrates the very cold nature of
the geotherm within the region encompassing Hudson's Greenland
Exploration Licences. It was generated from and forms
part of a larger report prepared by Dr. Herman Grütter,
of Mineral Services Canada. It demonstrates that the west
Greenland geotherm is substantially colder than the geotherms
pertinent to the Kirkland Lake and Somerset Island kimberlites
and arguably colder than the geotherm recorded by clinopyroxenes
in garnet lherzolite xenoliths from the Diavik, Gahcho
Kue (Kennady Lake) and Jericho kimberlites that are situated
in the Slave craton, Canada. As stated in the report,
"having a cold geotherm constitutes one of the fundamental
pre-requisites for the presence of diamondiferous, economic
or near-economic kimberlites. The presence of diamond-facies
harzburgite-derived G10 garnets, such as also found in
the Kangerlussuaq area (Jensen et al., 2003), constitutes
another prerequisite."
