Holocene volcanic soils in the Mt. Gambier region, South Australia [PDF]

, 2010
Volcanic soils derived from mid-Holocene basaltic tephra in the Mt. Gambier region of South Australia have developed in a xeric moisture regime. We studied two soils, one at Mt Gambier (MTG) and the other at nearby Mt Schank (MTS).
