In the summer of 1945, Dr. Victor M. López, Director of The Servicio Técnico de Geología y Minería in Venezuela’s Ministerio de Fomento, invited the writer to compile a tectonic map of the country. This was to accompany a new geologic map on the scale of 1 : 2,000,000 of which a tentative first draft had been prepared by the Servicio. When the writer accepted, he thought in terms of a generalized tectonic sketch on the same scale as the geologic draft map of the Servicio, showing only major structural units and trend lines, after the fashion of the Tectonic Map of the United States (1 : 2,500,000) which had been published the year before.

Using the “Geological Sketch-Map of the Western Venezuelan Andes” by L. Kehrer and E. Kündig (1 : 500,000), which had been published in the second volume of the Boletín de Geología y Minería in 1938, the writer prepared a sample sketch and submitted it to Doctor Kehrer for criticism and discussion. Doctor Kehrer not only entered whole-heartedly into the questions of design, but convinced the writer and Doctor López that a larger-scale map would doubtlessly serve its purpose better and suggested that possibly the Shell Company might release their topographical map of Venezuela (1 : 1,000,000) for use as a base, since a new edition was in preparation at the time, and offered his help in securing it. On that larger scale, it would then be possible to show both areal geology and structure lines . . .
