उदाहरण वाक्य
- The sediments and volcaniclastic sediments are of Precambrian Uriconian age and were deposited in rifts and basins that would have been sub-parallel to the back arc basin as subduction continued.
- Given the steep dip of the Uriconian rocks relative to the shallow inclination of the Cambrian, the Uriconian the tectonic events can be classed as pre-Atdabanian ( Stage 2, Lower Cambrian ).

- The sediments of the Uriconian are indicated to have been deposited rapidly with such volcanism being dated ( U-Pb Zircon ) at 566 + /-2Ma ( Note the Uriconian is cross-cut by the Late Precambrian Ercall Granophyre dated 560 + /-1Ma . ) The sequence is dominated by pyroclastic deposits, breccias and welded tuffs which is suggestive of a former volcanic centre being in close proximity and deposition in a subaerial environment.
