Geology and Resource Assessment of Costa Rica at 1:500,000 Scale--A Digital Representation of Maps of the U.S. Geological Survey's 1987 Folio I-1865

In 1986 and 1987, the U.S. Geological Survey (USGS), the Dirección
General de Geología, Minas e Hidrocarburos, and the Universidad de
Costa Rica conducted a mineral-resource assessment of the Republic
of Costa Rica. The results were published as a large 80- by 50-cm
color folio (U.S. Geological Survey and others, 1987). The 75-page
document consists of maps as well as descriptive and interpretive
text in English and Spanish covering physiographic, geologic,
geochemical, geophysical, and mineral site themes as well as a
mineral-resource assessment. The following maps are present in the
original folio:
1) Physiographic base map at a scale of 1:500,000 with hypsography,
place names, and drainage.
2) Geologic map at a scale of 1:500,000.
3) Regional geophysical maps, including gravity, aeromagnetic, and
seismicity maps at various scales.
4) Mineral sites map at a scale of 1:500,000 showing mines,
prospects, and occurrences.
5) Volcanological framework of the Tilarán region important for
epithermal gold deposits at a scale of 1:100,000.
6) Rock sample locations, mining areas, and vein locations for
several parts of the country.
7) Permissive areas delineated for selected mineral deposit types.
8) Digital elevation model.
This CD-ROM contains most of the above maps; it lacks items 1 and 8
and the seismicity and aeromagnetic maps of item 3.
