In the case of permafrost-associated settings in northern Alaska and Canada, gas-hydrate occurrences have been identified in sand-rich units deposited mainly in deltaic environments. Many of the deposits are thought [by whom?] to have formed during the last glacial period when ground temperatures cooled and formerly free-gas reservoirs likely ...

These deltaic materials have been deposited for 9000 years atop the bedrock at the mouth of the Pearl River in Guangdong Province, situated along the northern margin of the South China Sea. [ 1 ] This landform, replete with an intricate network of river channels, has been evolving since the Early Holocene era, shaping the contemporary delta ...
The environment of deposition for these sediments has changed, varying spatially and temporally. When the ocean level was high shallow marine deposits occurred; when they were low fluvial and deltaic deposits form the majority of mass. [26] From the Triassic until the early Jurassic, faulting localized as extension faulting and wrench faulting.
Mer Bleue Bog has a very popular autumn trail. Mer Bleue Bog is a 33.43 km 2 (12.91 sq mi) protected area in Gloucester, Ontario, an eastern suburb of Ottawa in Eastern Ontario, Canada.
Canada The Munising Group or Formation is a 1,700 feet (520 m) thick, white to light grey [ 1 ] Cambrian sedimentary unit that crops out in Michigan and (to a lesser extent) Ontario . At one end of its extent, it comprises a basal conglomerate overlain by the Chapel Rock Member and the Miners Castle Member; elsewhere, it comprises the Eau ...
A delta is a subaerial or subaqueous deposit formed where rivers or streams deposit sediment into a water body. Deltas, such as the Mississippi and Congo, have massive potential for sediment deposit, and can move sediments into deep ocean waters. Delta environments are found at the mouth of a river, where its waters slow as they enter the ocean ...
