| Inhoud: |
The sediments immediately adjacent to the Wyangala Batholith show direct evidence of two periods of folding. The first visible folds are tightly appressed structures which transpose the bedding to produce a new layering. The plunge of these folds is variable but there is no information to distinguish between superposition on an older generation of folds, and development in a heterogeneous strain field, as mechanisms to explain this variation. The first folds are deformed by a strain-slip cleavage which is axial plane for a second generation of folds. Geometrical analysis shows that large (macroscopic) structures exist and can be related to one or the other of the two generations of small scale folds. The general absence of transposition on a large scale introduces limitations into the use of geometrical techniques and, in one area, large errors result in the determination of the plunge of macroscopic folds. |
