Specimen: 2014-067
This sample is a metamorphosed limestone with a predominantly coarse, but locally fine, grained texture. The size and grain boundaries of most crystals reflect fairly complete metamorphism, indicating the rock is best described with the terminology of a marble, as opposed to a limestone. The texture is granoblastic with random grain orientation. Maximum grain size is near 3.5 mm, minimum is .05, and the modal size is approximately 2 to 1.25 mm. Fine and coarse grained areas are intermixed with no macro patterning. Twinning of calcite/dolomite crystals is common. Grain boundaries are a mix of sutured and straight equant-rhombohedra edges. Accessory minerals appear absent in this thin section. A few relict, but unidentifiable, fossil structures are visible, suggesting metamorphism was fairly low grade and insufficient to technically classify this sample as a marble in geologic terms. There is no appreciable macrostructure such as foliation or weathering visible in the thin section, but the hand sample clearly presents relict bedding and what are likely more preserved fossils.
