Figure 1-3. Transverse view of calcite crystals (C) in palisade fabric (view looking down crystallographic C axis). Note pore spaces (larger of which are marked with "P"s) between crystals and subtle boundaries between individual crystals (red arrows). An
image in cross-polarized light and an
image in plane-polarized light show this fabric in a more conventional longitudinal view. Photomicrograph was taken in parallel-polarized light (polarizer and analyzer parallel); field of view is 2.1 mm wide. Carlsbad Cavern, New Mexico, U.S.A.; Georgia Giant Stalagmite; thin section CB10. Sample collected by Dr. George A. Brook. |
