|FOLD INTERFERENCE, TYPE 2
This pattern develops when early nearly flat lying or recumbent to reclined folds are superimposed by late upriqht folds in a manner so that the axes of two sets of folds are at high angle to each other. In other words, the amplification direction of late folds lies at high angle to the axial planes of early folds and both the hinges and axial planes of early folds are folded about the axes of second generation folds. The typical outcrop pattern developed looks like that of a mushroom. Perhaps the best example of this on a large scale is from the Nathadwara area in Western Indian Aravalli belt where early Aravalli EW trending folds are refolded by later upright NS trending folds.
