| 41. | During the Cretaceous, low-relief drainage areas are completely transgressed and the clastic supply is shut off.
|
| 42. | Stratigraphically equivalent rocks on the mainland are clastic sediments with coal beds, marine to brackish fluvial units and travertines.
|
| 43. | Varves form in a variety of depositional environments from seasonal variation in clastic, biological, and chemical sedimentary processes.
|
| 44. | In general the Br�ches du Grand Fond Group consists of coarse grained clastic sediments composed of pre-rift lithologies.
|
| 45. | Lastly, the Wara formation is created by a fluvial system exposed to bio clastic dolomite known as the wara shales.
|
| 46. | The majority of the lower Triassic clastic sediments originated from a Variscan source area in northern France with minor local input.
|
| 47. | The formation consists of two members : clastic, mostly feldspathic various grained sandstones, and volcano erupted-alkali lavas.
|
| 48. | This alluvium is adjacent to and probably underlain by volcanic clastic rock deposited by Mount Shasta in the course of its development.
|
| 49. | As the graben dropped, it immediately began to fill with clastic sediment from the surrounding hills, creating the Chumstick formation.
|
| 50. | The stratigraphy of the Sauk sequence indicates shallow-water deposition, primarily consisting of well-sorted sandstones and clastic carbonates.
