Correlative microscopy of the constituents of a dinosaur rib fossil and hosting mudstone: Implications on diagenesis and fossil preservation
Fig 6
An area showing lateral variation of the 1M-type illite and the 2M-type illite within the same layer.
The gradual transformation of the 1M to 2M illite in a lateral direction is apparent. Note the highly disordered {00l} lattices of 2M from the HRTEM image.
