Title: Energy Source of Intrusive Masses: ABSTRACT

Author(s): William C. Gussow

Article Type: Meeting abstract


Textbooks of geology generally fail to discuss the motivating force of intrusive masses. Texture, composition, and shape are dealt with in detail, but the mode of emplacement is ignored. It is here postulated that the energy is almost entirely derived from the geostatic load of the overburden and that the mechanics involved in the emplacement of igneous dikes, volcanic plugs or necks, stocks, etc., is essentially the same as that involved in salt and ice piercements, and even the "frost boils" on northern roads. The mechanics of large basin downwarps is also discussed.
