[a. G. pluton (H. Cloos 1928, in Fennia L. ii. 1), back-formation from plutonisch plutonic a. (n.)]
An intrusive body of igneous rock formed beneath the earth's surface, esp. a large one.
[1933R. A. Daly Igneous Rocks & Depths of Earth vi. 75 He [sc. H. Cloos] states that he does not assume floors for batholiths but on the next page defines his ‘Plutone’, which includes batholiths, as having visible or inferable floors. ]1936Proc. Geol. Soc. Amer. 1935 67 The granite appears to have come up along the edge of the mostly consolidated Pikes Peak mass and spread in a series of plutons and sills, the mode of intrusion being largely governed by the rock invaded. 1942M. P. Billings Structural Geol. xv. 296 The intrusion of large plutons may be associated with orogenic movements. 1961F. H. Lahee Field Geol. (ed. 6) vi. 141 Concordant plutons include sills, laccoliths, lopoliths, and phacoliths. Ibid. 142 Discordant plutons include dikes, necks, chonoliths, batholiths, stocks, and bosses. 1962[see greisen]. 1971I. G. Gass et al. Understanding Earth v. 84/2 The observed linear relation between heat flow and heat production in granitic plutons may allow precise estimates of temperature as far down as the base of the crust. 1974H. F. Garner Origin of Landscapes iii. 130/2 Metasomatic replacement is common along borders of larger intrusive masses (plutons). |
