Figure 8-3. Euhedral calcite (C) and surrounding void space (V) in a stalagmite from Carlsbad Caverns. The calcite contains multiple growth zones (red arrows), suggesting mutliple late stages of precipitation and documenting growth laterally rather than in the overall direction of growth of the speleothem (which is upward in this view). Such growth is expected of diagenetic crystals.    Photomicrograph was taken in plane-polarized light; field of view is 2.2 mm wide. Carlsbad caverns, New Mexico, U.S.A.; Georgia Giant Speleothem; thin section CB84. Sample collected by Dr. George A. Brook.
