The most abundant sediment type in the two groups is fine-grained fluvial sandstone, although conglomerates and lacustrine siltstones also occur. We show that duricrusts, biogenic lacustrine precipitates, hydrothermal and chemosynthetic precipitates, speleothems, travertines and evaporites all contain low-temperature fluid inclusions which represent surface/very-near-surface fluids. The central plain lacustrine setting is the best preservation domain for ash falls interbedded with lacustrine claystones. Although more often attributed to climate fluctuations, many shallowing-upward lacustrine cycles might result from pulsating tectonism taking place contemporaneously with sediment deposition. The middle unit includes alluvial to lacustrine facies while the upper unit consists of fluvial-alluvial deposits. The lacustrine deposits include both upper- and lower-shoreface clastics. These chiefly represent major channel, floodbasin and extensive lacustrine and lake-delta facies within typical alluvial plain facies assemblages. They probably represent the most characteristic lacustrine facies and occur as horizontal, millimetre- to submillimetre-thick laminae (laminites). These species represent a stage in the vegetative succession from a lacustrine to a forest system. The park area at the foot of the escarpment consists of various lacustrine terraces and alluvial fans. Continued compression resulted in growing basement folds with anticlinal ridges gradually disrupting the lacustrine complex. The lagoon, immediately to its north, is a rich source of fish, shellfish, turtles, alligators, wild plant foods, and other lacustrine resources. At each of these sites nearly all metazoan parasites of arctic char are transmitted via the lacustrine food web. Such non-agricultural production remained focused on salt and other lacustrine resources, including comestibles. |
