Description:
Abstract:
Stratigraphic relations and mineral zones associated with stratabound copper-silver mineralization in the Revett Formation are based on the descriptions of 40 diamond-drill cores and 86 measured sections in the Revett Formation and adjacent strata. Most of this descriptive information was collected in the field by exploration geologists working for ASARCO Inc., although 5 sections were measured and compiled by USGS personnel. Rock type and sedimentary structures was recorded to understand the stratigraphy and depositional environment of the Revett Formation. The amount of sulfide, oxide, and silicate minerals in synsedimentary cements was also described in order to understand if the distribution of these minerals could be used to predict the occurrence of stratabound copper-silver mineralization. The observations were systematically collected on forms; colored or black-and-white paper copies of this data was provided to the USGS for this study. The information on the forms was compiled into Microsoft® Excel spreadsheets which was then used to create graphical logs of the data for each diamond-drill core and measured section.
Purpose:
These Excel spreadsheets were developed to provide digital lithologic data for 40 diamond drill holes and 86 measured sections.
Supplemental_Information:
Each Microsoft® Excel file for a diamond-drill core or measured section consists of four worksheets named lithology, formation, mineralogy, and collar. Four worksheets are required because depth intervals differ substantially for the different categories of information recorded on the field-forms.

Data_Set_Credit:
Mary H. Carlson reviewed the column headings and data in each of the 126 spreadsheets for consistency. Michael L. Zientek assisted Mary H. Carlson in creating concise definitions for each of the items (column headings).
Native_Data_Set_Environment:
Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.1.0.722
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy was verified by manual comparison of the four worksheets in each spreadsheet to the paper log by three persons multiple times. Column headings in each worksheet were verified to reflect consistent names.
Logical_Consistency_Report:
No duplicate features exist. Adjustments for apparent thickness to true thickness, inversion of overturned strata, or other corrections were made in spreadsheets, so finished graphical logs show true, undeformed stratigraphic thickness. Effects due to faulting or intrusions of igneous rocks could not be determined or removed but the positions of faults are identified on logs.
Completeness_Report:
These spreadsheets were derived from hand-drawn lithologic logs created by Asarco Inc., Kennecott Exploration, and USGS. The data recorded on the spreadsheets is of a sufficient level of detail that little or no geologic data recorded on the geologist's paper logs were lost. Considerable effort was devoted to retain the integrity of the paper log data. The lithologic logs were recorded by a number of geologists with vastly different backgrounds and skill levels, as a result, the data reflects this.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The overall accuracy (with respect to the location of points) of the data points is probably no better than +/- 100 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The overall accuracy (with respect to the depth of the sections) of the tabular data is probably no better than +/- 1 meter.

Depth (in feet) measured at the end of a stratigraphic interval for diamond-drill holes and measured sections in the stratigraphic down direction. Item contains "no data" if data were unavailable for the section. This item is attributed for diamond-drill holes and measured sections only where no correction is needed (they are already in stratigraphic down direction and holes were drilled at an angle not requiring a correction) so that the "to_corr" value (item name) will not be attributed.
