fluvio-lacustrine

The lowland is formed by fluvio-lacustrine loam soil about 120 m thick.

The paleoenvironment was a fluvio-lacustrine coastal plain.

Wine from this appellation grows on tertiary fluvio-lacustrine sediments that occur in three different forms:

This consists of grey siltstones and calcareous mudstones comprising two sequences of fluvio-lacustrine sedimentation with some alluvial fan and littoral (lake-shore) deposits.

The scarlet, ephemeral, mainly clayey fluvio-lacustrine deposits of the Alemoa Member gradually cede to more sandy, occasionally gravelly deposits of a braided river-system that was operational all-year-round.

It was found in fluvio-lacustrine sediments of the Middle Grey Unit of the Xinminbao Group, Gonpoquan Basin, Mazong Shan, Gansu Province, China.

The island formed from the gradual accumulation of sediments of fluvio-lacustrine origin and its natural landscape consists of three different areas: the margins, the high dunes area and the interior (depression on dunes).
