| Analytically, RLW vessels are mineralogically and geochemically homogenous and distinctive. |
| In this case the fossil consists of original material, albeit in a geochemically altered state. |
| Gabbro intrusions of the Cobequid Shear Zone are of olivine tholeiite composition and appear geochemically related to the basalt. |
| On the seabed the abundance of nodules varies and is likely controlled by the thickness and stability of a geochemically active layer that forms at the seabed. |
| A poorly exposed but geochemically distinct suite of peraluminous granites occurs in the Buchan terrain. |
| Of the three resulting rock suites, the East Hill suite is the youngest, the most geochemically evolved, and the subject of this investigation. |
