Partially melted lithic megablocks in the Yardea Dacite Gawler Range Volcanics, Australia: implications for eruption and emplacement mechanisms

, 1999
Lithic megablocks ranging from 200 m) felsic volcanic unit in the Mesoproterozoic Gawler Range Volcanic Province (GRV) of South Australia. Throughout its vast extent, the Yardea Dacite shows typical lava-like features, in that it is massive, columnar ...
