Description:

Abstract:

This coverage includes arcs, polygons and polygon labels that describe U.S. Geological Survey defined geologic provinces

of the World. Each province has a set of geologic characteristics distinguishing it from surrounding provinces.

These characteristics may include the dominant lithologies, the age of the strata, and the structural style. Some provinces

include multiple genetically-related basins. Offshore province boundaries are generally defined by the 2000 meter

bathymetric contour, but where appropriate are defined by the 4000 meter bathymetric contour. In some cases province

boundaries are delineated by political boundaries, as in the case of The United States and Canada, because United

States petroleum resources were assessed separately by the U.S. Geological Survey. Provinces are classified as either

Priority or Boutique. A priority province is one of 76 non-U.S. geologic provinces defined by the U.S. Geological

Survey that together contain 95 percent of the world's non-U.S. known petroleum volume. All priority provinces were

analyzed for undiscovered petroleum-resources.

A boutique province is a geologic province, other than a priority province, as defined by  the U.S. Geological Survey,

considered for petroleum-resource assessment. Boutique provinces can be chosen for a variety of geologic, political,

technical and geographic reasons. Resource-assessments are conducted by scientists of the U.S Geological Survey's

World Petroleum Assessment 2000 by means of a combination of Petroleum System analysis based on available

geologic information, and statistical analysis of production and exploration information. Total petroleum systems are

defined in provinces considered for assessment analysis. Total petroleum systems are subdivided into Assessment Units.

Assessment results from the analysis of assessment units and total petroleum systems are aggregated and allocated to

geologic provinces. Summary results are presented as attributes of this coverage.

Purpose:

This coverage is intended to delineate geologic provinces of the world used in the preparation of World Petroleum Assessment 2000,

and to present summary results of this assessment.

Supplemental_Information:

For data management purposes the world was divided into eight energy regions corresponding approximately to the economic

regions of the world as defined by the U.S. Department of State. Except in the case of the United States, most region and

province boundaries are not controlled by the presence of political or administrative boundaries. Geologic province boundaries

are determined by World Petroleum Assessment 2000 Regional Coordinators, and others, on the basis of natural geologic entities

and may include a dominant geologic structural element or a number of continuous elements. Geologic province boundaries, codes

and names defined by the Regional Coordinators are combined into a world-wide coverage. Some province boundaries are

adjusted for consistency with boundaries of Total Petroleum Systems. Summary results of World Petroleum Assessment 2000

are appended to this coverage.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The attribute values have been reviewed. This is a composite coverage composed of geologic provinces defined by Regional

Coordinators of the U.S. Geological Survey World Energy Project and others. There have been updates and corrections in

spelling of the names of the provinces since they were first published in Open File Report 97-463 (Klett and others, 1997).

Logical_Consistency_Report:

Polygon topology is present, each polygon has one unique label point, there are no dangles, polygons are bounded at extent of coverage

Completeness_Report:

Geologic provinces are delineated by U.S. Geological Survey World Energy Project Regional Coordinators and others with an emphasis

on the determination of petroleum systems. Methods may vary from one region to another. The coverage is updated. Spelling errors in

province names are corrected. In some portions, province boundaries are adjusted to more closely match surface geology, where

applicable. Some offshore province boundaries have been adjusted beyond the 2000 meter bathymetric contour to the 4000 meter

bathymetric contour to accommodate

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

It is not possible to calculate a definitive measure of the horizontal positional accuracy of this coverage because it is

a composite data set compiled from a variety of sources using a variety of methodologies. The maximum possible accuracy

is twice fuzzy tolerance of 500 meters, or 1000 meters. Because of the heterogenous variety of source data, generally of

small-scale, used in delineating the province boundaries, there is no datum or spheroid defined. At the average estimated

compilation scale of 1:5,000,000, there is not enough geodetic control to define a datum or a spheroid without introducing

false precision.

Process_Description:

Geologic province codes, names and boundaries are defined by Regional Coordinators and others. Priority and boutique

provinces are defined. Boundaries are drafted on mylar sheets placed upon a variety of geologic maps at a variety of scales.

Mylar sheets are scanned to produce digital images. Digital images are vectorized to produce Arc/Info coverages.

Process_Step:

Process_Description:

Arc/Info coverages produced by Regional Coordinators and others are combined to produce a coverage of geologic provinces

of the world. Discrepancies and overlaps between different regions are resolved. The coverage is projected to the Robinson

projection in Arc/Info as standard in the plotting of maps of the geologic provinces for the use of geologists in the determination

of Total Petroleum Systems and Assessment Units for World Petroleum Assessment 2000.
