TABULAR SUMMARY OF LITHOLOGIC LOGS AND GEOLOGICCHARACTERISTICS FROM DIAMOND DRILL HOLES IN THE WESTERNINTERNATIONAL FALLS AND THE ROSEAU I°x2° QUADRANGLES,
NORTHERN MINNESOTA
* BY TERRY L. KLEIN AND WARREN C. DAY
Introduction
This report is part of a folio of maps and other publications prepared under the Conterminous United States Mineral Assessment Program (CUSMAP). Other publications in this folio include U.S. Geological Survey Open-File Reports OF 87-0549 (Geologic Map of the International Falls Quadrangle),OF 87-366 (USGS geochemical analyses of drill core from the International Falls and Roseau Quadrangles), OF 88-525 (Supplemental USGS geochemical analyses from the International Falls and Roseau quadrangles), OF 88-575 (Tabulated geochemical analyses from exploration drilling in the International Falls and Roseau quadrangles), Miscellaneous Field Investigations Map MF-2082 (Mineral occurrence and drill hole location map of the International Falls quadrangle).
Drill core available in the Minnesota Department of Natural Resources (MDNR) Drill Core Repository in Hibbing, Minnesota, was examined and sampled during the study of the geology and mineral resources of the International Falls and Roseau CUSMAP projects. The drill core was studied both to characterize major geologic units deliniated by aeromagnetic and gravity surveys and to help define the mineral resource potential of the area. Approximately 3 months were spent examining drill core beginning in early 1985 and contining until the spring of 1987. During that time drill core from 107 drill holes containing more than 40,000 feet of core was examined, sampled, or logged by the authors.
In the area of the western 1/3 of the International Falls and the Roseau Quadrangle I°x2° quadrangles a total of 207 holes have been drilled and are or will be in the MDNR Core Repository (as of 4/1/89). The Minnesota Geological Survey (MGS), in cooperation with the USGS CUSMAP effort, drilled 21 of these holes (CUS-series) to provide information on the Quaternary stratigraphy and characterize the underlying bedrock with a 10-foot diamond drill core. A total of 68,314 feet have been cored with a diamond drill out of a total 105,050 feet (excluding the MGS cores) drilled during base-metal massive sulfide, gold, and iron exploration since 1952 in the area covered by this report. The average depth to bedrock as defined by this drilling is approximately 150 feet.
Method of investigation
Drill hole locations were digitized using the USGS GSMAP program from locations plotted on USGS 1:100,000 scale 1/2° x 1° quadrangles (International Falls, Baudette, Roseau, and Grygla). Locations were obtained where possible from the original location maps provided by the companies that drilled the holes. Where location maps were not available, locations obtained from the MDNR defined to the nearest 1/16 of a section were used.
Each drill hole labeled with a * in Table 3, column 3 was examined during the study. The degree to which a hole was studied was based on the complexity of the geology, its geologic or mineral resource significance, and the reliability of the available drill logs. Some drill holes were relogged in detail whereas others were spot checked and sampled for geochemistry and petrology only. Geochemical analyses of core samples are available in three of the open- file reports listed above. In general, each hole was examined to define its lithology, structure, metamorphic grade, alteration, and economic mineralogy.
The prefix MmetaM was not used in describing lithology because all of the rocks have undergone some degree of metamorphism except for some relatively unmetamorphosed Proterozoic diabase dikes.
Organization of Data
Location data both in Township, Range and Section and in latitude-longitude are given in Table 1. Other physical attributes of the drill holes such as depth, orientation of the hole, the angle at which it was drilled, and the depth to bedrock are tabulated.
Summary lithologic logs and major rock units percentages are tabulated in Table 2. If the hole was examined by us (see Table 3, column 3) that lithologic information is summarized. If the hole was not examined during this study, data from existing lithologic logs was used with modification to conform with our terminology and/or was reinterpreted using geochemical data that was not available during the intial core logging.
Table 3 summarizes petrologic, structural, alteration, mineralization, and interpreted depositional environment information by drill hole.
Some drill holes are listed in only one of the two tables containing geologic information (Tables 2 and 3). These holes were not logged during this study and information was not specific enough in the previous lithologic logs for inclusion in the database. Holes listed only in Table 1 were not logged during this study and have no reliable previous lithologic logs.
It should be noted that for Table 3 the information listed under Metamorphic Minerals are minerals observed in hand specimen and that those observations listed under the presences of the minerals listed under Mineralization of Economic Significance may have significance for the occurrence of several types of metallic mineral deposits. The information listed under Structural Interpretation, Volcanic Facies, Sedimentary Facies, and Environment represent our geologic interpretations based on examination of the drill core. These interpretations, coupled with the mineralogical and petrological observations, hopefully will provide a consistent database from which the user can extract both local and regional information. These data, combined with the published geochemical databases (USGS OFR 87-366, 88-525, and 88-575) provide powerful tools to users from the industrial and academic communities and agencies of Federal and State governments. In undertaking this project, we have strived for accuracy and consistency. As research continues some of our conclusions may prove invalid, however because of the uniform nature of data (for example, the same two people looking at the available core), the data bases can continue to be modified and updated and should prove useful in the future.

information is given in feet. Total length is the total cored interval. Proportion is the
thickness of a lithogic unit divided by the total cored interval. Proportions of lithologic units
were combined into generalized lithologic units which are expressed as a percentage of the cored
interval for each hole. The abbreviations used here are listed at the end of Table 3.
