INTRODUCTION

SUMMARYThis compilation contains data on industrial mineral mines and

mineral occurrences of Puerto Rico. These data have recently been entered in the U.S. Geological Survey's (USGS) Mineral Resources Data System (MRDS), a database of worldwide deposits and occurrences, in support of a mineral resource assessment of Puerto Rico. The data were compiled by the staff of the Center for Inter-American Mineral Resource Investigations (CIMRI) in the Fall, 1991. CIMRI is a group within the USGS that specializes in the geology and mineral resources of the Americas. The Puerto Rico industrial mineral records were constructed from skeleton records based on active mining activities as recorded by the Corteza Terrestre/Surface Mining Permits Office of the Puerto Rico Department of Natural Resources and augmented by geologic information and additional sites as shown on 1:20,000-scale geologic maps published by the USGS during the last 30 years.

MRDS

MRDS, originally named the Computerized Resource Information Bank (CRIB), is a database of mineral deposits and occurrences. The level of information on mineral deposits usually included in MRDS consists of commodity and geologic data that are useful for regional mineral resource assessments and reconnaissance exploration rather than in-depth site studies, although detailed records have been compiled for some well-studied mines and deposits. MRDS contains records on over 65,000 sites worldwide. Each record must include a certain minimum amount of detail. All records are routinely checked for consistency and uniformity using computerized methods and systematic expert review procedures. In some cases, the data have been interpreted and reflect the opinions of the record contributors and file editors. More complete data standards for the database are contained in the MRDS User Guide

(MRDS Project Staff, U.S. Geological Survey, 920 National Center, Reston, Virginia 22092).

A primary goal is to insure that each record faithfully reproduces the data source(s); this assumes that the data source contains valid information. On occasion, where there are glaring inconsistencies or the data are of poor quality, the reporte r must reconcile or report the inconsistencies or choose to exclude a record for that site. Regrettably, no database can be constructed or supported without introducing errors. The user, therefore, is advised to check the original data source materials whenever there are data problems with the compiled records. No claim is made for completeness of this compilation and users of the data should bear in mind that some published and unpublished sources may have been missed and that the data are no more accurate than the data sources. We welcome additions and corrections to the information in this report. Data changes may be submitted to the authors, CIMRI, MRDS staff, or Minerals Information Office staff.

MRDS runs on several commercial software packages:INFORMATION** (PRIME minicomputer environment), REVELATION (IBM-PC environment), and 4th DIMENSION (Macintosh environment).

Linkage and modifications to the software for MRDS applications are available from the U.S. Geological Survey. MRDS staff will provide limited support of the MRDS customized applications of the software. The Minerals Information Office* should be contacted if the data are desired in a different format including map plots or on computer diskette.

DATA

No previous comprehensive compilation of industrial mineral mines and occurrences was found to exist prior to this study. Copies of mining permit applications from the Corteza Terrestre-Surface Mining Permits Office of the Puerto Rico Deparment of Natural Resources were used to construct over 120 skeleton records which were entered into MRDS by Richard Kibbe. The information from this source included location, owner/operator, commodity, and production limit information. Mike Alien, Jim Bliss, Marguerite Carbonaro, Herb Pierce, Greta Orris, Norm Page, and John-Mark Staude added almost 300 additional records and supplied geology for the original skeleton records. The CIMRI staff used over 40 1:20,000-scale geologic maps published by the USGS since 1960 to determine the geology of these sites. This compilation totals over 450 industrial mineral mines and occurrences for Puerto Rico.

The largest mineral production in Puerto Rico is related to the manufacture of cement and over 140 of the MRDS records are for limestone and limestone aggregate quarries. Most of the limestone and limestone aggregate quarries mine material from the Miocene Aymamon Formation, although at least four other formations have significant limestone production. Other industrial minerals and materials that have been produced in Puerto Rico include dimension stone, silica sand, sand and gravel, aggregate and road metal, gypsum, barite, and phosphate. Other commodities such as barite, clay, and dolomite are known to occur on the islands.

The "RECORDS" section of this report contains a standardized listing of data for the study area sorted by quadrangle. Within each quadrangle, the records are listed alphabetically. The reader should note that additional information for some records may be available in MRDS.

EXPLANATION OF DATA FIELDS

A MRDS record contains up to 200 fields for recording a wide range of attributes. Some of the fields in the MRDS records listed in this compilation are described below. Particular focus is given to identification of codes and other formating standards which may not be obvious to the reader.

MRDS record numbers are assigned to each record in the database. A single record has been prepared for each site noted or groups of adjacent properties. Each record number is unique.

Report date is given as year and month, For example 91 03 -means the record was compiled in the thiird month (March) of 1991.

Reporter's name gives the last and first) names and middle initial of the reporter.

Reporter's affiliation gives the name of government agency, company, etc. with which the reporter was affiliated.

Site name is a name of ore body, deposit, or property used at the time the record was prepared. On average, half of the MRDS records will give a name for a mine, prospect, claim, occurrence, group or placer. In some cases, this may be the name of a nearby town or geographic feature. If not named, tjhe site may be "unnamed." or "unidentified" if likely named but the reporter does not know the name.

Svnonvms includes other names used for the site. Also listed arenames of several closely-spaced mifres that have been included in one record or names of individual orebodies. For placers, stream and gulch names which are part of the deposit are identified.

State (province, other) is used to give line name of a second orderpolitical division. If a site overlaps into two units, both are given.For Puerto Rico, "Puerto Rico" is also used as a second order political division.

Map names are for the l:20,000-scale Quadrangles in which the site is located.

Commodities list includes those of primary economic interest,coproducts and byproducts, those which have not been exploited but which are present in sufficient amount to be suspected to be of possible economic interest, and occurrences of geologic interest. The commodity codes are listed in table 1.

Ore materials are listed as reported or in order of abundance from most to least.

Production indicates if there is known production from the site and, if possible, its relative size. Codes for this field include L (large), M (medium), S (small), Y (yes, production has occurred but the amount is unknown), N (no production), and U (site production status is uncertain).

Status contains a numeric code representing the production- development status of the site and the level of current activity. The codes are as follows: 1- mineral occurrence; 2- inactive prospect; 3- active prospect; 4- inactive producer, very small production; 5- active producer, very small production; 6- inactive producer; 7- active producer; 8- intermittent producer.

Deposit types are usually based on morphology, etc. Table 2 contains deposit types commonly used in MRDS, but the list is not all inclusive.

Deposit size gives an estimated relative size of total tonnage of past production plus the estimated reserves.

Host Rock Ages are given using the age designations shown in table 3.
