Abstract

Outline 1. Ascent of basic magmas into deep intermediate chambers 33 2. The physical representations of the intrusion of basic magmas in the middle and upper layers of the crust and the mechanisms of areal and lateral basaltic eruptions 34 a. Mechanics of intrusion of basalts through fissures to form dikes and sills b. Estimates of the times of solidification of dikes and deep sills c. Minimum rates of intrusion and flow of magmas for chambers at various depths d. Maximum rates of steady flow of basalts through dikes e. Nomogram for estimating V, w, h, and n. Expected properties of basaltic dikes and fissure eruptions 3. The great Tolbachik fissure eruption of 1975-1976: Mechanism of eruption, intrusion of basalts, and comparison of theory with observations 43 References 46
