Abstract
The Mt. Lofty-Olary arc is the result of a deep-seated crustal folding which commenced in the Pre-Cambrian and continued with alternating phases of paroxysm and quiescence through Palaeozoic, Mesozoie and Tertiary times. The Archaean crystalline basement, which forms anticlinal cores in the Mt. Lofty and Olary axial culminations, played the active rôle in the folding process, the sedimentary mantle adjusting itself passively by sharp curvatures of the lower beds and broad undulations at higher levels. Faulting, where it occurs, is regarded as a subordinate effect of a diastrophism controlled by folding.Keywords
