Ken:
I haven't seen any IP data over kimberlite. I would expect that a weathered
kimberlite would have clay magnitude. The highest response from massive clay I've
seen is 8msec for 2sec on-2sec off pulse. More typically, an IP response from clay is
around 4msec.

Subject: [SEGMIN]: IP Response of Kimberlites
Dear All:
I have been trying to get a better idea of the IP response of kimberlites. I have a
paper written by Jim McNae where he suggests a quite low value (~3 msec). Any other
comments?
Regards
Ken
