| Description: | Marmorized limestone with white mica, quartz and albite. Composed of elongated crystals of calcite, granulitized and arranged with their long axes parallel, and showing composite lamellar twinning; grain-size varying from 0.5 - 1.0 mm. The white mica occurs in-flakes up to 0-4 mm long, either distributed among the calcite or concentrated into streaks and bands. Quartz and albite reaching 0.5 mm in size but generally about 0.2 mm across, are abundant. Graphite is associated with muscovite and albite. Iron ore occurs fairly plentifully in aggregates or fine disseminations as pyrite, or oxidized to limonite or leucoxene. Limestone with quartz, albite and muscovite, granoschistose, foliated. GS0002. Britrocks S35996. Magnification x40. Light XPL. |
