Slide #31
Microscope Magnification : 100X
Approximated Field Width : 1mm
1634.8 H PPTL of material and needles in pores. Some diagenetic process is filling pores and reducing open porosity at this level.
Slide #32
Microscope Magnification : 100X
Approximated Field Width : 1mm
1634.8 H XPTL of material and needles in pores. Some diagenetic process is filling pores and reducing open porosity at this level. (Same view as Slide 31)
Slide #33
Microscope Magnification : 40X
Approximated Field Width : 2.5mm
plane polarized transmitted light1634.8 V Note - calcium carbonate fossils are now silicified (no birefiingence in crossed polars).
Slide #34
Microscope Magnification : 40X
Approximated Field Width : 2.5mm
cross polarized transmitted light, 1634.8 V Note - calcium carbonate fossils are now silicified (no birefiingence in crossed polars). (Same view as Slide 33)
Slide #35

Approximated Field Width : 2.5mm
same as Slide 34, different exposure time.
cross polarized transmitted light, 1634.8 V Note - calcium carbonate fossils are now silicified (no birefiingence in crossed polars). (Same view as Slide 33)
Slide #38
Microscope Magnification : 100X
