THE VARVES AND CLIMATE OF THE GREEN RIVER EPOCH By WILMOT H~ BRADLEY ABSTRACT. The Green River formation is a series of lake beds of middle:Eocene age which occupies two large intermontane basins, one in Colorado and Utah, the other in Wyoming.
The formation averages about 2, feet in thickness and covers an area ofCited by: The varves and climate of the Green River epoch. [Wilmot H Bradley] Home. WorldCat Home About WorldCat Help. Search.

Basinal facies of the Green River Formation have two main modes, lacustrine and playa. The lacustrine mode (Tipton and Laney members) accumulated mainly varved oil shale.
Here annual cycles are recorded as varves. Variations in verve thickness demonstrate El Nino (ENSO)-type and sunspot cycles (Ripepe et al., this volume). The proof that varves represent annual deposits can be quite compelling.
Berrill, in his book Man's Emerging Mind, tells of a varved shale from the Miocene Epoch of Switzerland: Certain shales of Miocene age in Switzerland bring that ancient world as vividly to life as any poster advertising the glories of a Swiss canton.
The Green River fish fossil shown to me by my colleague also points to significant water deposition.” 9. I added a conjecture about the so-called varves: “Many years ago, following massive flooding and major ice-sheeting in northern (and southern) regions, the earth, seeking as it were to attain thermo-equilibrium, started to melt the ice.
The varves and climate of the Green River Epoch. U.S. Geol. Surv. Profess. Papers E, 87– (). These varves are known as symmict varves and are common in brackish water environment. Of the many rhythmites found in the geological record, varves are one of the most important and illuminating to studies of past climate change.
Varves are amongst the. The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season.

Eocene Epoch - Green River Formation deposits are found in Colorado, Wyoming and Utah, generally along the present-day Green River. As an important lagerstatte, the Green River Formation sediments represent a continuous record of deposition that spans a 5 million year period from to mya.
In a detailed formation originally described by the first geologist to take a close look at it, (Bradley, Wilmot H.,"Varves and Climate of the Green River Epoch," in USGS Professional Paperp.
) the 4 cyclical layers range in thickness from mm for the sandstone to mm for the oilshale deposits. The Green River Formation, a lake deposit in Wyoming, Colorado, and Utah from the Eocene Epoch, contains too many varves to count.
Using average varve thicknesses in various beds of this formation and the total thickness of those beds, Bradley () calculated that ~ million varves are present, which indicates that the lake accumulated.The BioLogos Foundation has published a popular-level article by old-earth geologists Gregg Davidson and Ken Wolgemuth presenting arguments for an old earth.
One such argument involves counts of sedimentary laminations (“varves”) within the floor of Japan’s Lake Suigetsu.
Their article claims that the very large number of Lake Suigetsu varve counts is strong evidence for an old earth.
