Working for many years with Civil engineers,  I never saw and I don't know what is that unit  "Mg"  to measure the amount of shale-oil rock.


It would be good  (and NECESSARY)  if it be explained in the post


(although I  197%  sure that the person who posted and invented it,  does not know it, too).
