These variants commonly display an irregular fine lamination, but are otherwise extremely uniform, although locally banding may be present. |
The sandstones show variable grading, with planar, rippled and undulatory lamination. |
Hot laminators provide a better quality, more durable lamination that is more resistant to wear and tear. |
With the possible exception of some early Chinese fossils, the origin of lamination significantly post-dates determinacy and dorsiventrality. |
At an embossing station, at least one embossment is provided in at least each of the laminations preceding the last lamination. |
Intervals of siltstone and fine sandstone show climbing ripple lamination and low-angle cross-bedding. |
