Marble from Slovenia
CRM-CJNMarble, Calcite CaCO3
Field of View: 0.2 mm
The microstructure of marbles:
Polygonal aggregates of calcite in an extremely fine-grained marble from marble quarry Stahovica, Kamnik.
Ultrathin section manufactured by Günter Grundmann. The thin section has been ground and polished on both sides much thinner than usual, namely to about 0.015 mm thickness (= 15 μm). Base of photo 0.2 mm.

YJW-M0MMarble, Calcite CaCO3
Field of View: 0.2 mm
The microstructure of marbles:
Polygonal aggregates of calcite in an extremely fine-grained marble from marble quarry Stahovica, Kamnik. The deformation twins and grain boundaries are visible as single dark lines.
Ultrathin section manufactured by Günter Grundmann. The thin section has been ground and polished on both sides much thinner than usual, namely to about 0.003 mm thickness (= 3 μm). Greyish colours are off-colours caused by quartz compensator. Base of photo 0.2 mm.

AVA-083Marble, Calcite CaCO3
Field of View: 8 mm
The microstructure of marbles:
Polygonal aggregates of calcite in an extremely fine-grained marble from marble quarry Stahovica, Kamnik. The bright areas are shape relics of microfossils.
Ultrathin section manufactured by Günter Grundmann. The thin section has been ground and polished on both sides much thinner than usual, namely to about 0.007 mm thickness (= 7 μm). Greyish colours are off-colours caused by quartz compensator. The dark lines are healed fractures. Base of photo 8 mm.
