Digging out Argillaceous Limestone and Marlstone
Digging out Argillaceous Limestone and Marlstone in the hills behind Taormina and Castelmola in Sicily. These are lime-rich mudstones which contains variable amounts of clays and silt. The dominant carbonate mineral in most marls is calcite, lake chalk is sometimes used to describe it in Europe. This may have been burnt locally to produce hydraulic hot lime mixes.
Womersleys are running a training course in Sicily in March 2018 and this includes a lime kiln burn using this stone
