Exempel på hur man kan använda ILLINOIAN i en mening

• During the Illinoian Stage of the Pleistocene, the Laurentide Ice Sheet covered about 85 percent of Illinois, including the Macon County area.
• Till and outwash from the Illinoian glaciation covers area bedrock to a depth of several hundred feet.
• A small area of the Allegheny Plateau was glaciated during the Wisconsin Stage, the late Illinoian Stage, and Pre-Illinoian B and G glaciations of the Pre-Illinoian Stage.
• The Wolstonian Stage is temporally analogous to the Warthe Stage and Saalian Stage in northern Europe and the Riss glaciation in the Alps, and temporally equivalent to all of the Illinoian Stage and the youngest part of the Pre-Illinoian Stage in North America.
• In this exposure, the Illinoian Glasford Formation, in which the interglacial Sangamon Soil (palesosol) has developed, is overlain by early Wisconsinan stage loess, called the Roxana Silt.
• From youngest to oldest, they were the Wisconsinian Stage (glacial), Sangamonian (interglacial), Illinoian (glacial), Yarmouthian (interglacial), Kansan (glacial), Aftonian (interglacial), and Nebraskan (glacial) stages.
• The last occurrence of the Monongahela Lake outburst was an outwash gravel dam backed up slackwater at Allegheny-Monongahela confluence during an Illinoian ponding event during the last glacial retreat.
• The Pleistocene prior to the Illinoian stage had previously been subdivided into the Nebraskan, Aftonian, Kansan, and Yarmouthian stages (ages).
• The start of the Sangamonian Stage is constrained by optically stimulated luminescence (OSL) dates obtained from fluvial deposits of the Pearl Formation and Illinoian glacial tills of the Glasford Formation, which fill an ancient and buried Mississippi River valley in north-central Illinois.
• The Iowan surface in northeast Iowa is covered with eroded Illinoian till with moderate loess formation, frequently in the form of paha ridges, muted relief except for steep rolling hills near river valleys, and deeper valleys.
• The surficial geology in the area mainly features Illinoian Till, Illinoian Leg, alluvium, colluvium, and bedrock.
• The surficial geology in the area mainly consists of Illinoian Till, Illinoian Lag, alluvium, colluvium, and bedrock.
• The surficial geology in its vicinity consists of colluvium, alluvium, Illinoian Till, Illinoian Lag, and bedrock consisting of sandstone and shale.
• The surficial geology in the area consists mainly of bedrock, along with alluvium, colluvium, Illinoian Till, and Illinoain Lag.
• Following the time-line, the next stratum is contemporary to the Riss glaciation in the Alps region (corresponding to the Illinoian in America) and contains few artefacts, still in the same cave of the Hyena.
• Early Lake Estancia, most likely larger than the LGM lake, existed possibly during the Illinoian glaciation and largely dried up in the warm and dry climate of the Sangamonian interglacial.
