| Lithological Description: |
Limestone-dominant gravels occurring at the base of the Wolston Glacigenic Formation. The unit includes bodies of purplish clay (cf. Moreton Member (MTON)), and has an interfingering relationship with evident outwash gravels. It is probably a composite deposit of scree/head gravels partly reworked by outwash during ice advance. The gravels have yielded a molar of mammoth (Richardson and Sandford, 1960). |
