Hi people
This may be a naive question, but it stems from a paper I was just reading
on a gold deposit in the Northern Territory of Australia. The deposit, Gold
Creek, has been interpreted as having a phase of graphite alteration. My
question is: How common is graphite alteration? I don't know of the
metamorphic grade of the rocks, but since it is in the Pine Creek Inlier I
don't think it is that high. I was under the impression that graphite
alteration was a high-grade phenomena. Most graphite I've seen in gold
deposits occurs as a residual concentration due to dissolution of more
soluble elements and because we were originally dealing with carbon-bearing
sediments eg the argillaceous rocks of the Hodgkinson Province in north
Queensland.
Thanks in advance for any info.
Cheers
Brett
