Burgess Shale-type Preservation and its Distribution

Burgess Shale-type fossil assemblages provide a unique record of animal life in the immediate aftermath of the so-called "Cambrian explosion." While most soft-bodied faunas in the rock record were conserved by mineral replication of soft tissues Burgess Shale-type preservation involved the conservation of whole assemblages of soft-bodied animals as primary carbonaceous remains often

PAPER OPEN ACCESS Validation of shale brittleness index

The parameter of the shale brittleness index is the key to success in hydrocarbon shale stimulation as in Barnett Shale Texas USA where brittleness is controlled by quartz content. Based on the mineral content of the shale the ductility (opposite of brittleness) is controlled by the content of clay and calcite.
