Division of Geology and Mineral Resources

Limestone is a chemical (or organic) sedimentary rock that is composed of lime mud and/or crystalline calcite, and may contain shells and skeletons of fossil marine organisms. Limestone often forms in quiet shallow marine environments. Due to the variety of marine settings in ia, limestone is most common in the Valley and Ridge province.

Argillite

Argillite (/ ˈ ɑːr dʒ ɪ l aɪ t /) is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are basically lithified muds and oozes.They contain variable amounts of silt-sized particles.The argillites grade into shale when the fissile layering typical of shale is developed. Another name for poorly lithified argillites is mudstone.

 · In the early stage of SQ1 (Mao-1c–Mao-2c), the lithology was dominated by dark gray argillaceous limestone. The high positive carbon isotopes, which increase slowly constantly, indicate a large paleo-water depth and slowly rising paleo-sea level. In the late stage of SQ1 (Mao-2b), a relatively pure carbonate rock began to deposit.
