AC18.10660

Shale

The material consists of flagstone rock sourced from an operating (Mintaro) quarry located approx. 110km north of the city of Adelaide in South Australia. This Proterozoic (~800 Ma) siliclastic sedimentary rock is part of the Mintaro Shale Formation originally deposited in a quiet, relatively deep-water marine (outer shelf) environment. The mineralogy consists of quartz (35 %), biotite (16 %), dolomite (12 %), muscovite-sericite (12 %) and plagioclase (10 %) with minor amounts of chlorite, kaolinite, and calcite.

AC18.10660 is available as 50 g units packed into glass, wide-mouth jars.
