Grand Canyon GigaView #25 Blacktail CanyonJul 10, 2020 by magic-gigapansImage: Thomas HaydenSubject: Subject ID: 22408 x 9600 pixelshttp://GigapanMagazine.org vol 3 issue 1 The Great Unconformity - Welcome to the surface of the Earth, approx. 550 million years ago. The first layer of rock, at ground level here, is called the Vishnu Schist. It consists of several complex sets of sedimentary and volcanic that were laid down 1.8 billion years ago, but were buried and metamorphized into schist and gneiss about 400 million years later. By 550 million years ago, the Vishnu Schist was exposed as a flat, rocky plain that was inundated by the sea. The upper, layered rock is the Tapeats Sandstone and is made of beach sand. The Tapeats begins the sequential series of deposition that ends at the top of "The Grand Staircase" of the American Southwest. What happened in the 1.2 billion years of Earth's history between the deposition of this basement rock layer and its final exposure is still unknown to science. One thing that is known is that life came to Earth. There is no evidence of fossils or trace of bacterial colonies in the PreCambrian schist and gneiss, but the Tapeats Sandstone and the layers above it show the rich tapestry of evolution through a fairly continuous fossil record.

Double unconformity at Beinn Garbh, North-West Highlands, ScotlandApr 17, 2020 by magic-gigapansImage: Callan Bentley, Mid-Atlantic Geo-Image CollectionSubject: Subject ID: 59500 x 8608 pixelsTwo unconformities for the price of one: Beinn Garbh (north of Canisp), viewed from the north across Loch Assynt. Most of the mountain is Torridonian Applecross Formation, with Lewisian gneiss below (making up the hummocky ground between the mountain and the loch) and with gray Cambrian quartzite on the left (east) dipping off to the left (east) at about 15 degrees. |
Carmel Valley River DepositsJul 10, 2020 by magic-gigapansImage: ahochstaedterSubject: Subject ID: 37452 x 10536 pixelsThe Proto-Carmel River deposited these river gravels thousands of years ago. The gravels were deposited on top of Monterey formation, a Miocene diatomaceous mudstone. Since the Monterey formation is gently dipping to the left (wesst) in this image, the contact is an angular unconformity. Since depositing the gravels, the Carmel River has eroded down through its own detritus and the underlying Monterey formation bedrock, leaving these river gravels resting on the side of the Carmel Valley. Turn around 180 degrees from this spot to enjoy a view of the present-day Carmel Valley: http://gigapan.org/gigapans/94758 |

Contact between Tensleep Formation and Goose Egg Formation, east of Shell, WyomingApr 29, 2020 by magic-gigapansImage: Callan Bentley, Mid-Atlantic Geo-Image CollectionSubject: Subject ID: 17913 x 3957 pixelsWest of Shell, Wyoming, on route 14, there is a lovely exposure showing the tilted disconformity between the lower Tensleep Formation (purple; Pennsylvanian period) underneath Goose Egg Formation (orange/tan; Permian to Triassic in age). The contact dips to the west because it has been deformed during Laramide mountain-building (uplift of the Bighorn block, and downdropping of the Bighorn basin). |

Turbidites at Garrapata Beach, Big Sur, CaliforniaJul 10, 2020 by magic-gigapansImage: ahochstaedterSubject: Subject ID: 37640 x 18436 pixelsCretaceous turbidites crop out along the sea cliff at Garrapata Beach in Big Sur, CA. Turbidites are characterized by graded bedding with coarser clasts at the bottom and finer material at the top of the deposit. They are recognized here by the alternating sands and shales in the sea cliff. Turbidites are deposited by turbidity currents, density-driven flows that occur when sediment and water mix to create a fluid with a density higher than that of water. This high density slurry flows down slope and can keep moving over a long horizontal distance after it reaches the bottom of the slope. This processes produces submarine fans at the base of continental slopes; turbidity currents are one of the most important mechanisms for transporting sediment from the continent into the deep ocean. Idealized turbidite deposits have five layers distinguished by their sedimentary structures. These layers were first described by Bouma, and bear his name today. From bottom to top, the Bouma sequence consists of sands or larger grains, parallel laminated sands, cross laminated sands, parallel laminated silts, and muds. Seeing these various layers may be beyond the focus limits of this image, but they are easily visible on close-up images of these beds: The turbidite beds are overlain in angular unconformity by beach sands with a basal boulder layer, visible in the center right portion of the image. This angular unconformity formed while these rocks were being eroded on the wave-cut platform of a previous beach. As uplift continued, the rocks and the overlying sand and gravel beach sediments rose above sea level to form a marine terrace. Marine terraces are visible above the sea cliff left of center in the image. Close-up images of the turbidites are here: http://zoom.it/dKU6 http://zoom.it/4v4T |
