Abstract
At various places in the Archaean areas of Missouri the granites and porphyries are cut by dikes of basic rocks which usually trend N. E. and: S. W. but occasionally in other directions. The dike rocks are comparatively constant in composition. When holo-crystalline they are a diabase, or an olivine diabase, and when less perfectly crystallized they generally correspond to diabase porphyrite.
