Abstract

Pebble dikes are intrusive features associated with the forceful emplacement of magmas. Farmin (1934) and Lovering (1949), who studied pebble dikes at their type area in the Tintic District, Utah, describe them as vein- or dike-like bodies composed of rounded, subangular, or angular pebbles of materials derived from local formations in a matrix of finer-grained pebble material or of intrusive rock. In the course of the field investigation of the Topia Mining district in the northwest part of Durango, Mexico, pebble dikes were observed cutting the andesite rocks of the area. These dikes at Topia were similar to the pebble dikes at Tintic which the writer has also had the opportunity to study in the field. The presence of these dikes at Topia was of great interest because they contain the only sedimentary rocks in the entire region, and shed more light on the mechanics of intrusion in the area.
