Graded bedding is a sorting of particles according to clast size and shape on a lithified horizontal plane. The term is an explanation as to how a geologic profile was formed. Stratification on a lateral plane is the physical result of active depositing of different size materials. Density and gravity forces in the downward movement of these ...
Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition . Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. [ 1] These beds range from millimeters to centimeters ...
Load casts are bulges, lumps, and lobes that can form on the bedding planes that separate the layers of sedimentary rocks. The lumps "hang down" from the upper layer into the lower layer, and typically form with fairly equal spacing. These features form during soft-sediment deformation shortly after sediment burial, before the sediments lithify ...
Cleavage is a type of secondary foliation associated with fine grained rocks. For coarser grained rocks, schistosity is used to describe secondary foliation. There are a variety of definitions for cleavage, which may cause confusion and debate. The terminology used in this article is based largely on Passchier and Trouw (2005).
Flaser bedding, vertical section. Flaser beds are a sedimentary, bi-directional, bedding pattern created when a sediment is exposed to intermittent flows, leading to alternating sand and mud layers. While flaser beds typically form in tidal environments, they can (rarely) form in fluvial conditions - on point bars or in ephemeral streams, or ...
Dwell mechanism. A single-dwell linkage. The orange circle shows the circular arc the coupler curve is approximating. A camshaft with two single-dwell cam-follower mechanisms. A dwell mechanism (either a linkage or cam -follower type) is an intermittent motion mechanism that alternates forward and return motion with holding position (s). [ 1]
ISSN. 1530-5309. Dwell is a design and technology brand. It was launched with a magazine in October 2000 by CEO Lara Hedberg Deam with architecture and design critic Karrie Jacobs as its editor-in-chief. In August 2002, Jacobs left the magazine and was replaced by senior editor Allison Arieff. After Arieff, Sam Grawe held the position from 2006 ...
