Possible of Piercement structures, local unconformities, and secondary basins in the Eastern Geosyncline, New Zealand

Abstract

Piercement structures, local unconformities, and secondary sedimentary basins observed in the Eastern Geosyncline are often closely associated with transcurrent fault-zones. Spasmodic and uneven transcurrent movement along these faultzones is thought to be responsible for the features. Their probable development is shown diagrammatically.
