Dear all, with the present discussion about organic material in rocks I
wish to ask this question - How does one isolate all organic material from a
black shale? Not only the bitumen matter, but the Kerogen matter too - All
organic matter!!!!
I have used the HF-BO3 technique to remove the silicates, but this procedure
appears to have caused demineralization of elements Re and Os (already known
to remove Ni) from the organic material.
I wish to isolate the organic from the black shale in order to analyse the
organic material for Re and Os.
Can any one help in this task?
I look forward to hearing from you and thank you for your time.
Regards, Dave Selby
