Geology of the Voinjama quadrangle, Liberia

As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period 1965 to 1972. The resulting geologic and geophysical maps are published in ten folios, each covering one quadrangle (see index map). The Voinjama quadrangle was mapped by eleven geologists who worked in different areas at various tines (see inset map). Compilation of field data, interpretation of geophysical data, interpretation of aerial photographs, and field checks by helicopter and motor vehicle traverse were the responsibility of J. F. Seitz.
