|Figure 9-6. High-magnification image of one columnar calcite crystal (C1), at the boundary between clear and inclusion-rich areas shown in a another image at lower magnification. Note that the parallel linear inclusions (arrow) in the inclusion-rich calcite extend into the clear calcite. This relationship suggests that the euhedral front (dashed line) of the clear area has engulfed the arrowed linear inclusion, and that the euhedral area at the bottom of this image has formed via recrystallization of the inclusion-rich calcite.
Photomicrograph was taken in plane -polarized light; field of view is 0.35 mm wide. Wadi Sannur Cavern, Egypt; Sample EE9; thin section EE9. Sample collected by Dr. Adel Dabous.
