Flow-foot breccia in the Upper Lachlan valley, NSW, probably formed when Early Miocene lavas dammed the Lachlan River and lava flow continued into the resultant lake. The distribution of the breccia and its non-brecciated lateral equivalent indicates flow in the Early Miocene Lachlan River in the same direction as at present. Other evidence for the lava-dammed lake includes palaeocurrent data consistent with flow into the lake, a small outcrop of fine-grained, laminated sediments which would have been under the lake waters and, near the flow-foot breccia, abundant silicified wood which probably resulted from drowning of the local vegetation, progradation of the flow-foot breccia around the trees and their subsequent silicification. |
