Thanks for the reply mineman. Interesting as always. Here are a few more thoughts:

<< Mapping was done in 1996 and published in 1998 at 1:50 000.

I would not argue with you for the 3 anomalies within the volcano-sedimentary rocks. They could be related near surface gabbroic
intrusions.

But the one in the granite batholith (the NWI one) is difficult to
correlate with the others since the granite intruded millions of years
later and only diabase dikes (and possibly kimberlites) are the only
post-granitic intrusives in this area. From the description made by NWI, it is not a kimberlite nor a diabase dike.

This is why I think it is a remnant of a pre-granitic differentiated
intrusive. >>

If it is as suggested, the implications for additional discoveries at depth are positive. The question, of course, is how deep could they be?

Regards,

Bob
