Geologic Mapping, New Mexico

GGI and LANL geologists describing Pleistocene lake bed deposits in Valles Caldera National Preserve

GGI was responsible for mapping of surficial deposits in the Mt. Taylor area for the New Mexico STATEMAP program. The focus of this mapping effort was the mapping of fluvial and alluvial fan deposits and associated geomorphic surfaces, and completion of soil descriptions to differentiate between Quaternary deposits in the Lobo Springs and Mt. Taylor Quadrangles. GGI also focused on delineating contacts with underlying Cretaceous stratigraphic units and contributed to mapping of the Cretaceous section.

GGI also participated in mapping fluvial, lacustrine, and alluvial fan deposits and associated geomorphic surfaces in Valles Caldera sub-basins, including Valle Toledo and Valle Grande, in the Valles Caldera National Preserve. This fieldwork entailed collection of stratigraphic, structural, and soil stratigraphic data .
