Description:

Abstract:

Map interface and data download of Sed Zn-Pb data including KML and GIS data formats

Data_Quality_Information:

Logical_Consistency_Report:

Information here is derived from many previously published sources. Corrections in locations were made by consulting commonly available imagery in web services such as Google Earth.

Completeness_Report:

Sediment-hosted Zn-Pb deposits are hosted in a variety of sedimentary rocks and have commonly been classified into skarns, polymetallic replacements, Mississippi Valley Zn-Pb (MVT), Sedimentary-exhalative Zn-Pb (SEDEX), sandstone-hosted Pb, Kipushi, and polymetallic vein types. Some of these types have been further subdivided by various authors (Allen, 2003). In this study we include all of these types except polymetallic vein deposits because of their relatively small size.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

All deposit locations have been checked by comparison with GoogleEarth imagery. Many deposits have locations in these files that are substantially different than published locations as a result. Generally location is intended to plot within the alteration zone of deposit which may be kilometers across.

Process_Description:

Dataset authors gathered information from previously published reports.

Deposits selected

A mineral deposit is a mineral occurrence of sufficient size and grade that might, under the most favorable circumstances, be considered to have economic potential (Cox, Barton, and Singer, 1986). Deposits sharing a relatively wide variety and large number of attributes are characterized as a “type,” and a model representing that type can be developed. Sediment-hosted Zn-Pb deposits are hosted in a variety of sedimentary rocks and have commonly been classified into skarns, polymetallic replacements, Mississippi Valley Zn-Pb (MVT), Sedimentary-exhalative Zn-Pb (SEDEX), sandstone-hosted Pb, Kipushi, and polymetallic vein types. Some of these types have been further subdivided by various authors (Allen, 2003). In this study we include all of these types except polymetallic vein deposits because of their relatively small size.

Spatial rules used

An important consideration at the data gathering stage is the question of what the sampling unit should be. Grade and tonnage data are available to varying degrees for districts, deposits, mines, and shafts. For the deposits in this file, the following rule was used to determine which ore bodies were combined. All mineralized rock or alteration within two kilometers was combined into one deposit for these deposits. Thus, if the alteration zones of two deposits are within two kilometers of each other, they were combined. Such an operational spatial rule is necessary for defining deposits because we must be able to classify deposits in regions with highly variable geologic information and to avoid bias in estimating undiscovered deposits in resource assessments in areas where detailed information is lacking, such as under cover. The two-kilometer rule was developed to try to insure that deposits in grade and tonnage and spatial density models correspond to deposits as geologic entities. Rules, such as the two-kilometer rule applied here, are essential in order to have an internally consistent assessment system where the estimated number of undiscovered deposits is consistent with the grade and tonnage model.
