Abstract

A sequence of intrusions ranging in age from 220 m.y. to 22 m.y. andcomposition from ultramafic to granitic are present in the metamorphiccore of the northern Cascade Mountains. The oldest of these arecatazonal and mostly concordant, whereas the youngest have subvolcanicelements and are nonconcordant. The silicic intrusions arecompositionally depth dependent. The deepest are deficient inpotassium; the potassium seems to have migrated upward andprecipitated as biotite and orthoclase in the higher rocks. Probablyall epizonal intrusions grade into catazonal at depth.--from NewPublications of the Geological Survey, August 1983.
