This sample is a predominantly coarse grained metamorphosed limestone with portions of locally fine grained texture. The size and grain boundaries of most crystals reflect fairly complete metamorphism, indicating the rock is more easily 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 1.75 mm, minimum is .05, and the modal size is approximately 1 to 1.25 mm. Fine and coarse grained areas are intermixed with no macro patterning. Twinning of calcite/dolomite crystals is ubiquitous. Many twin lamellae are curved, suggesting post formation stress. Grain boundaries are mostly sutured, but straight equant-rhombohedra edges are present at a low frequency. Only one non-carbonate accessory mineral was noted; it occurs in the same size range as the coarse calcite component and is isotropic with distinct cleavage. Periclase seems a plausible identification. The only visible weathering is rare incipient cracks that are beginning to infill with clay sized particles. These cracks are less than .05 mm in width and mostly follow existing grain boundaries. A few grains present features that may be relict fossil structures, indicating relative low grade metamorphism overall that is likely insufficient to geologically classify this rock as a marble. There is no appreciable macrostructure such as foliation visible in this section, but such structures including visible in-filled cracks are visible in the hand sample. The cracks visible in thin section can seen to be stylolites in hand section.
