Igneous and Associated Rocks from the Andes of Eastern Ecuador

Resumen

The suite of volcanic and metamorphic rocks described in this paper were collected by the writer in the early part of 1929. With the exception of the micaceous slate (Pl. XVIII, Fig. 3), which was found in situ along the valley of the Rio Patate near Guadaloupe, all the specimens were obtained near the Cascada de Agoyan, a locality a few miles downstream from Baños along the Rio Pastaza.
