Road Log From El Paso/Ciudad Juarez Via Villa Ahumada and El Sueco to Ciudad Chihuahua, and Santa Eulalia

January 01, 1990


Much of the first day's route is spent in travelling in a southerly direction through desert basins to Chihuahua City (Fig. 1). Numerous ranges are visible from the roadside and some stops are scheduled for description of lithologies and structures, particularly where mapping has been accomplished. Of particular interest is the lower Cretaceous in Sierra del Presidio and Banco Lucero, Los Medanos (dune field), Sierra La Candelaria and Sierra El Kilo intrusions, and the Tertiary volcanic stratigraphy of Sierra Gallego (near El Sueco), Sierra El Nido, Sierra de La Campana, and Sierra Sacramento. The Sierra de Samalayuca, near the community of the same name, has been considered by some to be Early Jurassic or Paleozoic in age, and it consists of weakly-metamorphosed sediments in an anticlinal structure.

The underground visit to the manto and breccia-pipe deposits at the Potosí mine, West Camp, Santa Eulalia completes the day.
