Schellekens Description: Abstract: This compilation summarizes the metallic mineral mines, prospects, and occurrences of Puerto Rico. The metallic and mineral data discussed here have been complied and entered, in support of the mineral resource assessment of Puerto Rico, into the U.S. Geological Survey's (USGS) Mineral Resources Data System (MRDS), a database for worldwide mineral deposits and occurrences. These sites were extracted from MRDS records compiled from previous mineral occurrence maps (Cox and Briggs, 1973), literature searches, and public company records on file at the Puerto Rico Department of Natural Resources, San Juan. Purpose: An inventory of known mineral deposits and less-understood mineral occurrences is essential in the evaluation of the potential mineral resource endowment of an area. For this reason, great care was used to identify and document metallic and nonmetallic industrial mineral occurrences of Puerto Rico. Previous studies of Puerto Rico, many of which were conducted on specific commodities or in restricted areas, examined known mineral deposits and occurrences. The "Metallogenic Map of Puerto Rico" (Cox and Briggs, 1973) combined mineral sites from these studies into a comprehensive compilation. In this study, deposits and occurrences described in Cox and Briggs are augmented with additional published and unpublished information by reviewing the original literature and other sources. New MRDS records were prepared to incorporate data found in the files available at the Department of Natural Resources in San Juan, Puerto Rico. Supplemental_Information: The occurrences of metallic minerals, shows an association of mineral deposit types by spatial distribution. Each deposit type is represented by a unique symbol accompanied by a site number. Those occurrences for which a deposit type could not be determined due to lack of information are represented by the abbreviation of an element known to occur at this site. Certain mineral deposit types tend to be found in proximity to one another. If geology, geologic terrane, and metallic mineral occurrences are considered, it can be seen that granitic intrusive rocks tend to be associated with skarn and vein deposits. Gold placer deposits can be found in sediments downstream in drainage basins crossing areas that contain gold-bearing porphyry, skarn, and vein systems. Nickel laterite deposits are concentrated in southwestern Puerto Rico, where they have developed on weathered serpentinite. Volcanogenic manganese deposits display a northwest-southeast trend that corresponds to outcrops of Tertiary volcaniclastic rocks.

In some cases the points are transferred from a 1:240,000 scale map, and in other cases the locations are very accurate because of mining company descriptions or field checking. The MRDS record for each site should be examined in order to determine the accuracy of the location. Logical_Consistency_Report: Point features present.

The ITEMS AREA, PERIMETER, METALLIC#, and METALLIC-ID are Arc/Info generated and should not be altered. SEQNCE is the sequence number used to uniquely identify each mineral site on plots. DEPID is the MRDS record number associated with each site. LAT and LON are the latitude and longitude expressed in decimal degrees. MODEL contains the unique model identification number found in Cox and Singer Prof. Paper 1693. SYMBOL contains the unique symbol type and color used to represent each deposit type.
