Very cool rock! Dev and I were offered a parcel this by a rough dealer who knows my love of inclusions. It is herkimer like quartz with petroleum (the yellow liquid) and bituminous solid inclusions. This particular piece also has a three phase inclusion of an air bubble that moves with the solid in the petroleum! I think it is my favorite rock of all time. I started a thread on the Mindat.org message boards: http://www.mindat.org/mesg-11-61219.html They are such a wonderful, knowledgeable group. Some of the best mineralogists in the world hang out there!
