Figure 4: Petrographic analysis (a-b) and SEM images (c-g) of KL-3 stalagmite. (a) polished thinsection from upper middle part with multiple compact layers; (b) high resolution image of upperpart with flat-topped calcite (C) layers; (c) SEM image at depth of 1.5 cm showing long columnar calcite (CC), arrows indicating the orientation and termination of calcite crystals; (d) palisade calcite (PC) at 3.0 cm depth, arrow indicating interwoven calcite; (e) palisade calcite (PC) at 9.5cm depth, arrow showing straight parallel crystal boundaries and approximate crystallographic orientation between the crystals; (f) interwoven trigonal crystals of equant calcite (EC) at 12.0 cm, arrows showing parallel orientation of crystals; (g) porous layers at 6.2 cm showing the presence of microsparitic calcite (MSC), arrows indicating arrangement of MSC crystals with a few voids.
