Petrographic Description: 

Specimen: 2014-076-1
This sample is a relatively coarse grained marble. The texture is overall granoblastic with random grain orientation. Maximum carbonate grain size is around 2.2 mm, minimum is .1 mm, the modal size is a wide range between .3 to 1.5 mm. Grain boundaries are mostly curved or straight with a lesser amount of sutured boundaries. Twinning lamellae in carbonates are common and rarely show evidence of pressure deformation. The most common non-carbonate accessory minerals are quartz and feldspar (albite twinning) that occur as individual crystals and small aggregates. Individual quartz grains have a maximum dimension of .4 mm, most are significantly smaller. The aggregates of quartz grains reflect strain induced nucleation of grains. Other minerals such as micas (muscovite, phlogopite?) and opaques are present only in trace amounts. All non-carbonate accessory minerals constitute less than 3 percent of slide area. Small diffuse clouds of darker minerals are minimally present in the hand sample. There is no appreciable weathering in this sample.

Specimen: 2014-076-2
This sample is a relatively coarse grained marble. The texture is overall granoblastic with random grain orientation. Maximum carbonate grain size is around 2.15 mm, minimum is .1 mm, the modal size is a wide range between .4 to 1.2 mm. Grain boundaries are mostly curved or straight with a lesser amount of sutured boundaries. Twinning lamellae in carbonates are common. The most common non-carbonate accessory minerals are quartz and feldspar (albite twinning) that occur as individual crystals and in small aggregates. Individual quartz grains have a maximum dimension of .4 mm, most are significantly smaller. Other minerals are relatively rare, micas (muscovite, phlogopite?) form aggregates in small bands ~.2 mm wide and generally under 2 mm long. Opaques occur in these bands and as individual crystals. Very rare amphiboles (richterite, tremolite?) occur in trace amounts. There is one localized band of a low birefringence mica or platy mineral (chlorite?) .2 by 1.4 mm in size that is likely the result of an alteration product. All non-carbonate accessory minerals constitute less than 5 percent of slide area. There are only very faint and diffuse clouds of darker minerals visible in hand specimen. There is no appreciable weathering in this sample.
