Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale. They often take shape when minerals precipitating (settling) out of water collect around a nucleus, such as a pebble, leaf, shell, bone, or fossil. Concretions most often form in sediment before or as the sediment is ...This chapter is devoted to geologic structural discontinuities that accommodate displacements perpendicular to their surfaces, including opening-mode fractures such as cracks, joints, veins, and dikes and closing-mode structures referred to as anticracks (Table 4.1). Opening-mode structures (mode-I, Fig. 1.16) are one of the most common types ...

Science Sep 29, 2023 6:05 PM EDT. Multi-billion-year-old mud cracks on the surface of Mars are helping researchers piece together the ancient history of our planetary neighbor’s climate ...In mud, crack patterns are frequently seen with either an approximately rectilinear or hexagonal tiling. Here we show, experimentally, how a desiccation crack pattern changes from being dominated by 90° joint angles, to 120° joint angles. Layers of clay, a few mm thick, were repeatedly wetted and dried. When dried, the layers crack.Mudcracks are diagnostic sedimentary structures indicating subaerial exposure of sediment surfaces. They are much more common that raindrop imprints, which indicate the same environmental setting. Mudcracks are most likely to occur in fine-grained siliciclastic rocks, fine-grained carbonate sediments, and in some evaporitic successions. ...

This photo is typical of the Race Track, a dry lake bed in Death Valley, CA. These larger mudcracks form in muds that accumulate between large sand dunes during rare rain storms.Callan Bentley is Associate Professor of Geology at Piedmont Virginia Community College in Charlottesville, Virginia.

Desiccation structures originate as shrinkage cracks formed by the evaporation of water from the surface of clay-rich sediment. Previously called mud cracks, they are of subaerial origin, and are caused by the slow drying-out of muddy sediments which have been exposed to the action of sun and wind. The volume decrease that results from this ...Noun [ edit] mudcrack ( plural mudcracks ) ( geology) A crack formed in the surface of mud sediment as it dries and contracts.
