The subduction of bathymetric highs such as aseismic ridges, oceanic plateaus, and seamounts has been posited as the primary driver of flat slab subduction. [3] The Andean flat slab subduction zones, the Peruvian slab and the Pampean (Chilean) flat slab, are spatially correlated with the subduction of bathymetric highs, the Nazca Ridge and the Juan Fernandéz Ridge, respectively.
[11] [12] Marianas Trench is an example of a deep slab, thereby creating the deepest trench in the world established by a steep slab angle. [13] Slab breakoff occurs during a collision between oceanic and continental lithosphere, [ 14 ] allowing for a slab tear; an example of slab breakoff occurs within the Himalayan subduction zone.
The Pampean flat-slab is one of three flat slabs in South America, the other being the Peruvian flat-slab and the Bucaramanga flat-slab. [ 1 ] It is thought that the subduction of the Juan Fernández Ridge , a chain of extinct volcanoes on the Nazca Plate , is the underlying cause of the Pampean flat-slab.
A slab and counter slab, more often called a part and counterpart in paleoentomology [4] and paleobotany, [5] are the matching halves of a compression fossil, a fossil-bearing matrix formed in sedimentary deposits. When excavated the matrix may be split along the natural grain or cleavage of the rock.
Slab pull force, the tectonic plate force due to subduction; Slab suction, one of the major plate tectonic driving forces; Slab window, a gap that forms in a subducted oceanic plate; Slab (fossil) and counter slab, the two counterparts of a fossil impression; Slab hut, a kind of dwelling made from slabs of split or sawn timber; Slab of beer, a ...
Heat-expanded lightweight pebbles. Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln.
The Flatirons near Boulder, Colorado, is both an example of these landforms and the source of their name. Other well-developed flatirons are found in the eastern Uinta Mountains in northwestern Colorado, [6] the Waterpocket Fold in Capitol Reef National Park, the Superstition Mountains near Phoenix, Arizona, and on the flanks of the Marathon Uplift in west Texas.
Slabs are one of the greatest consumers of concrete in many buildings, [14] so reducing the slab mass can make a relatively large difference to the environmental impact of a building's construction. Biaxial slabs may be marginally cheaper than solid slabs, partly due to the lower mass.
