Relations of Debris Size and Slope with Distance along Two Rhyolite Pediments in the Arid Environment of Rajasthan

Abstract

Studies on the relations of debris size and slope with distance along two rhyolite pediments at Kui Jodha in Jodhpur district reveals that the variation in lithological character has significant control over the rate of diminution of debris size. The more weatherable the rock is, the less significant is the relation of the distribution of debris produced with the distance along the pediment. Slope angle does not change appreciably with distance. Since the rate of reduction in debris size is faster along the pediments than the rate of change in slope, it may be inferred that the progressive diminution of debris size may have some control on the flattening of slope towards the distal end.
