I've seen the stuff from Disko and the metal is MUCH more sparse than
Putorana. Plus the matrix is very grey and dull.

Hi there folks,
Further to the Putorana thread... whilst it is said that this material is
one of the best meteorwrongs around, I have never seen any of the other iron
in basalt contenders (ie material from Disko Isl. &c.)
Has anyone out there got any pics of the other iron in basalt from these
other sources?
I was just interested to see if they were similar in appearance.
I could see that one of the arguments supporting Mr. Norton's hypothesis
that the iron in Putorana was sourced from a plume from the core was the
presence of Ni. Would not any iron derived from mantle rocks also have a
%age of Ni in it?
very best!
