| The deepest layer is gabbro, coarse-grained but chemically equivalent to basalt, which forms when magma cools and crystallizes slowly. |
| The highest core recovery occurs in the massive olivine gabbro, which contain lower densities of fractures and are generally undeformed. |
| Permian and Triassic plutonic complexes comprise monzonite, granite, granodiorite or tonalite with minor gabbro and diorite. |
| Contacts between plutons of gabbro or hybrid rock and granite are commonly marked by net-vein complexes. |
| A dioritic pod in varitextured gabbro was sampled for U-Pb age determination. |
| The group includes melange which consists of greywacke, limestone, pillow lava, gabbro and serpentenite blocks in a black shale matrix. |
