| Carbonaceous shale, including oil shale, occurs in beds of clayey to silty mudrock from 0.3 to 3 m thick. |
| This distribution defines an antithetic relationship between breccia facies in the red mudrock sequences and stratiform mineralization. |
| The TGRA has an unsteady tectonic structure, where geological hazards such as earthquakes, landslides, and mudrock flows frequently occur. |
| In response to burial in sedimentary basins, clay minerals in mudrock lithologies, including mudstone, shale and slate, undergo diagenetic and low-grade metamorphic reactions. |
| In this interpretation, the Basic Complex consists of basalts, pillowed in places, and derived volcaniclastic rock together with background mudrock. |
| The Cretaceous Winton and Mackunda Formations are composed of interbedded mudrock, sandstone, coal and carbon-bearing mudrock. |
