The horse is the broad lens-shaped feature in the rock defined by the splitting and rejoining of the trace of the fault plane. A horse, in geology, is any block of rock completely separated from the surrounding rock either by mineral veins or fault planes. In mining, a horse is a block of country rock entirely encased within a mineral lode. [1]
Dike – A sheet of rock that is formed in a fracture of a pre-existing rock body; Dirt cone – Depositional glacial feature of ice or snow with an insulating layer of dirt; Dissected plateau – Plateaus area that has been severely eroded so that the relief is sharp; Doab – Land between two converging, or confluent, rivers

A sieve, fine mesh strainer, or sift, is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet ...
A conglomerate or any clastic sedimentary rock that consists of a single rock or mineral is known as either a monomict, monomictic, oligomict, or oligomictic conglomerate. If the conglomerate consists of two or more different types of rocks, minerals, or combination of both, it is known as either a polymict or polymictic conglomerate.
A rocker box (also known as a cradle or a big box) is a gold mining implement for separating alluvial placer gold from sand and gravel which was used in placer mining in the 19th century. It consists of a high-sided box, which is open on one end and on top, [ 1 ] and was placed on rockers .
A geologist's hammer, also known as rock hammer, rock pick, geological pick, or geo pick, is a specialized hammer used for splitting and breaking rocks. In field geology , it is employed to expose fresh rock surfaces, as weathered surfaces may obscure accurate analysis of a rock's composition, bedding orientation, mineralogy , history, and ...
Abrasion generally occurs in four ways: [1] [2] glaciation slowly grinds rocks picked up by ice against rock surfaces; [3] solid objects transported in river channels make abrasive surface contact with the bed with ppl in it and walls; objects transported in waves breaking on coastlines; and by wind transporting sand or small stones against ...
