| The Marble Hills area comprise limestone/marble bedrocks with an intermittent cover of till with predominantly sandstone, quartzite, metasedimentary and some |
| ferromagnesian rich rocks; till sequences are not clearly expressed and the till which is from a non local source, may have been reworked by local ice masses |
