Sorry I cannot Crispin, but don't misunderstand me, I wouldn't expect this carbonate to be a big part of low temperature chars, I was referring to when the char is reheated in a retort to a higher temperature for analysis. Of course carbonates exist for long periods in alkaline soils and the sea, which at the moment is barely alkaline.
