talus (tā`ləs), deposit of rock fragments detached from cliffs or mountain slopes by weatheringweathering,
collective term for the processes by which rock at or near the earth's surface is disintegrated and decomposed by the action of atmospheric agents, water, and living things. Some of these processes are mechanical, e.g.

The constant weathering to which a talus is subjected, which breaks the rock fragments into finer pieces, and the impact of new material being added from above give the base of the talus a tendency to creep and slide. The term talus is often used to refer to the fragments themselves.TalusSloped architectural feature, such as a battered wall or an inclined retaining wall against an embankment.Talus (talus deposits), drifts formed at the base and on the lower parts of the slopes of elevated areas as the result of the washing out of disintegrated rocks from the upper parts of these slopes by rain and snow water and also because of the force of gravity, frost displacement, and soil movement (solifluction). The products of weathering that constitute talus are varied (from clays and sands to large boulders) and are characterized by weak sorting. In petrographic composition, talus differs from its underlying bedrock, revealing its relation to the rocks that crop out higher on the slope and on the peaks of the elevated areas. Talus is common in mountain areas. Talus deposits on the lower parts of slopes usually form mantle-like covers (talus trains), which soften the transition to the adjacent plain. Talus frequently contains placer deposits of gold, tin, tungsten, and other metals. Talus loams are used in the making of bricks. Academician A. P. Pavlov identified talus as one of the genetic types of continental deposits (1888). REFERENCESPavlov, A. P. “Geneticheskie tipy materikovykh obrazovanii lednikovoi i pozdnelednikovoi epokhi.” Izv. Geologicheskogo komiteta, 1888, vol. 7, no. 7.

Talus an accumulation of rock fragments at the base and on the lower part of a steep mountain slope. Talus forms when rock weathers and fragments roll down a slope. The material is un-sorted and usually consists of angular fragments varying in size from sand grains and chippings to blocks several meters across. The angle of repose of a talus slope is between 30° and 40°, close to the angle of the natural slope. Talus shows differing degrees of stability depending on the steepness of the slope angle. talus[′tal·əs] (anatomy) astragalus (geology) Also known as rubble; scree. Coarse and angular rock fragments derived from and accumulated at the base of a cliff or steep, rocky slope. The accumulated heap of such fragments. talus, tallus1. The slope or inclination of any work, as a talus wall. 2. Coarse rock fragments, mixed with soil, at the foot of a cliff or natural slope.talusenUK
ankle [ang´k'l] 1. the joint between the leg and foot.2. the area around this joint (see illustration). Ankle. The ankle is a hinge joint formed by the junction of the tibia" >tibia and fibula" >fibula with the talus" >talus (ankle bone). The bones are cushioned by cartilage and connected by a number of ligaments, tendons, and muscles that strengthen the joint and enable it to be moved. Because it is in almost constant use, the ankle is particularly susceptible to injuries, such as sprain and fracture. It is also often one of the first joints to be affected by arthritis or gout.tarsus (def. 2).talus.ankle cuff a weighted strip wrapped around the ankle and closed with a Velcro band; used during exercise.ta·lus, gen. and pl. ta·li (tā'lŭs, -lī), [TA] The bone of the foot that articulates superiorly with the tibia and fibula to form the ankle joint inferiorly with the calcaneus to form the subtalar joint, and anteriorly with the navicular, forming the medial component of the transverse tarsal joint.
