Schellekens Description: Abstract: This compilation summarizes the nonmetallic mineral mines, prospects, and occurrences of Puerto Rico. The nonmetallic 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 In this study, deposits and occurrences described in Cox and Briggs are augmented with additional published and unpublished information by reviewing the original literature and other sources.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. Industrial mineral commodities of Puerto Rico have not received the attention they deserve. No published comprehensive compilation of industrial mineral mines and occurrences was found to exist previous to this mineral resource assessment. Because of their low unit value, high transportation costs, and perception of not being "glamorous," the characteristics of formation and mode of occurrence of industrial minerals have not been very well documented. Of the industrial commodity occurrences, approximately 120 have permits active in 1991, as reported by the Corteza Terrestre Surface Mining Permits Office of the Puerto Rico Department of Natural Resources, San Juan. Additional records for 300 occurrences were collected by the USGS from more than 40 geologic maps at a scale of 1:20,000. This compilation resulted in more than 450 industrial mineral mines and occurrences being documented for Puerto Rico. Supplemental_Information: The occurrences of nonmetallic 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. Certain mineral deposit types tend to be found in proximity to one another. Patterns of occurrence for the industrial minerals show most permit sites located proximal to the coastline and, more importantly, within short distances of modern highways. Sand deposits, important to the construction industry, are contained in recent surficial sediments that blanket much of the north and south coasts.

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.
