Deformation of a substance, which disappears when the deforming forces are removed. Commonly, that type of deformation in which stress and strain are linearly related, according to Hooke's law. Compare: plastic deformation
Industry:Mining
Deformation of rocks accomplished by rupture rather than by flowage.
Industry:Mining
Deformation that takes place in sediments during or immediately following their deposition. Includes many varieties of soft-sediment deformation, such as small-scale slumps, crumpling and brecciation, but in some areas features of large dimensions.
Industry:Mining
Deforming metal plastically at such a temperature and rate that strain hardening does not occur. The low limit of temperature is the recrystallization temperature.
Industry:Mining
Delay in a blasting explosion caused by dampness of the powder or by too slow combustion of the fuse.
Industry:Mining
Delimited by having the boundaries ascertained and monumented on the ground, identified by having a notice of location posted upon the land, and further proclaimed to the public by having such notice of location recorded in the manner customary under the rules for recording mining claims.
Industry:Mining
Delineation of the size, mineral content, and disposition of an orebody by drilling boreholes.
Industry:Mining
Denotes a very common microlithotype in Japanese Tertiary coal. It consists of the macerals vitrinite, degradinite, and exinite. The dull bands of many Japanese Tertiary humic coals consist largely of hydrite and generally occurs alternating with vitrite as microfine bands, one or the other predominating.
Industry:Mining
Dense medium of the density required to achieve a given separation.
