- W50463896 abstract "Traditionally, discordant pluton/country-rock contact relationships are attributed to passive'' pluton emplacement, whereas concordant relationships are attributed to forceful'' pluton emplacement. Actually, concordance and discordance from a continuum (0 to 90[degree]), vary strongly around single plutons. The degree of discordance along a contact segment depends on many factors, including: (1) geometry, intensity, and mechanisms of emplacement-related deformation; (2) initial relative orientation of country rock structures and the pluton margin; (3) strain significance of country-rock structures; and (4) effects of pre-, syn- and post-emplacement regional deformation. Discordance records the truncation and subsequent transfer of country-rock material out of the path of the ascending magma, either in a horizontally-directed sense or in a vertically-directed sense. Roof structures should indicate the dominant direction of country-rock material transfer. The roof rocks above a pluton emplaced primarily by horizontal country-rock transfer must be either structurally detached or highly extended, whereas roof rocks are expected to be unextended above a pluton emplaced primarily by vertical country-rock material transfer. The authors initial observations from contiguous pluton roofs and walls, such as the Yerington batholith, Nevada, Mt. Stewart batholith, Washington, and the Mt. Powell batholith, Montana, suggest that vertical, downward country-rock material transfer has been important during emplacement ofmore » these shallow- to moderate-level plutons. They believe that erosional removal of the roof rocks from many plutons may have biased previous interpretations of emplacement mechanisms, and that vertical country-rock material transfer processes, such as stopping, may be more prevalent than currently recognized.« less" @default.
