Abstract
DURING the past twelve years Dr. George Sheppard has published a series of papers on various aspects of the geology of Ecuador. In this volume, which is probably the first published in English on the geology of Ecuador, he puts on record his collected data and his conclusions. The present climate and physiography are described together with the effects produced by this type of climate. The origin of the Tertiary Clay Pebble Bed of the Santa Elena region is a matter of controversy. It has been suggested that it is a crush breccia on a regional scale, but Dr. Sheppard takes the view that it was originally of the nature of a series of extensive mud streams similar to those which have been observed at the times of the heavy rains. He puts considerable emphasis on the results which may arise from these rather exceptional climatic conditions.
