Carbonaceous matter in Kumtor

 

Interbedded CM-poor and CM-rich layers

CM in S2 cleavage planes
CM in bedding-parallel layers and in S2 fabric pressure solution planes occurring in phyllitic clasts in hydrothermal breccia
Bleaching around the vein is caused by partial removal of CM and pervasive seriitization, chloritization, silicification, and carbonation.
Redistribution of CM.  Some areas are bleached, whereas others (confined to faults and fractures) are enriched in CM.,
"Graphitic fault" bears clay alteration and CM
