Pakohe or Argillite Nelson, Marlborough
There are at least 16 quarries which Jim Eyles and I recorded on the Nelson Mineral Belt of this very hard rock. (Walls, J Y. (1974). Argillite quarries of the Nelson mineral belt. Newsletter (New Zealand Archaeological Association), 17, 1, ) The description of quarrying by use of fire and water at the Rushpool has long been discredited.
