Mineralisation:
The material consists of siltstone rock sourced from an operating (Donnybrook) quarry located approx. 29 km north of the city of Melbourne, Victoria. This very pale orange (moderately weathered) Upper Silurian, siliclastic sedimentary rock is part of the Melbourne Formation originally deposited in a quiet, relatively deep-water marine (outer shelf) environment. The mineralogy consists of quartz (59 %) and muscovite/sericite (23 %) with minor vermiculite, phlogopite, plagioclase, K-feldspar and tourmaline. The rock is also anomalous in As, Au, Bi, La, Sb, W and Sn.
AC18.10663.0100 is available as 50 g units packed into glass, wide-mouth jars.
