Century Dictionary and Cyclopedia
    • n outcrop The appearing at the surface of a stratum or series of strata, or of a vein or ore-deposit of any kind. The outcrop of a metalliferous vein or lode is frequently more or less concealed by the accumulation of partly decomposed material (see gossan), the result of the decomposition and oxidation of the metalliferous part of the lode by atmospheric agencies. This is called by Cornish miners the broil. The outcrops of many veins, on the other hand, are very conspicuous, especially when the amount of ore present is small, quartz forming the predominating veinstone of a large proportion of the mineral deposits, and being very indestructible. The outcrops of the stratified formations depend on the amount of inclination of the beds. When these lie quite horizontal, there can be no outcropping edges of the strata, except when the formation has been cut into by erosion. The position on the surface of any outcrop depends, therefore, on the inclination of the bed or vein in question, and on the nature and amount of the erosion which has taken place See cut under dip.
    • outcrop To crop out or up; specifically, in geology, to come out to the surface of the ground: said of strata.

    • n Outcrop owt′krop the appearance, at the surface, of a layer of rock or a vein of metal, caused by tilting or inclination of the strata: the part of a layer which appears at the surface of the ground
