INTRODUCTION

This digitally compiled maps include geology, geologic provinces, and oil and gas fields of the

Asia Pacific Region.  The map is part of a worldwide series of maps on CD-ROM released by the

U.S. Geological Survey's World Energy Project.  The goal of the project is to assess the

undiscovered, technically recoverable oil and gas resources of the world and report these results by

the year 2000.  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.  The Asia Pacific Region (Region 3) includes Australia, Brunei, Cambodia,

The People's Republic of China, Fiji, Indonesia, Japan, North and South Korea, Laos, Malaysia,

Mongolia, New Caledonia, New Zealand, Papua New Guinea, Philippines, Thailand, Vanuatu, and

Vietnam.

Each region is divided into geologic provinces.  Each province has a set of geologic characteristics

that distinguish it from surrounding provinces.  These characteristics may include the predominant

lithologies, the age of the strata, and the structural style.  Some provinces include multiple

genetically-related basins.  Geologic province boundaries are delineated using data from a number

of geologic maps and other tectonic and geographic data (see References).  Offshore province

boundaries are defined by the 2000 meter bathymetric contour.  Each province is assigned a unique

number.  Those provinces that lie entirely within the Asia Pacific Region begin with the number 3.

Those provinces that lie partly within another region may start with a 1, for the Former Soviet

Union (Persits and others 1998) or an 8, for South Asia (Wandrey and Law, 1998).

The location of oil and gas fields centerpoints are plotted based on the locations in the

Petroconsultants International Data Corp. (1996) database with permission.   Selected provinces are

currently being investigated, by petroleum system analysis, and assessments are being made of the

undiscovered oil and gas resource potential of these provinces.  Klett and others (1997) discuss the

worldwide geologic provinces and their relative ranking in terms of total known petroleum volume.

For specific details of the data sources and map compilation see PROCESSING STEPS or the

metadata files on this CD-ROM.  Some stratigraphic units are combined to simplify the map and to

ensure consistency across the region.  Sedimentary and metamorphic rocks are shown by age and

are not differentiated.

This map is compiled using ESRI (Environmental Systems Research Institute Inc.) ARC/INFO

software.  Political boundaries and cartographic representations on this map are taken, with

permission from ESRI's ArcWorld 1:3m digital coverages: they have no political significance and

are displayed as general reference only.  Portions of this database covering the coastline and

country boundaries contain intellectual property of ESRI (

DATA PROCESSING STEPS

The maps on this CD were digitally compiled and abstracted from the following maps:

Geological Map of South and East Asia, Third Edition, 1990

A. Ghose, D. Chatterjee, and J. Banerjee,

UNESCO, Commission for Geological Map of the World,

Subcommission for South and East Asia

Scale 1:5,000,000

Geological Map of the World: Australia and Oceania, Sheets 6,7,11, and 12, 1965

Bureau of Mineral Resources (now Australian Geological Survey Organisation)

Scale 1:5,000,000

Geological Map of the World: Australia and Oceania, Sheets 2, 3, and 8, 1967

Bureau of Mineral Resources (now Australian Geological Survey Organisation)

Scale 1:5,000,000

Geological Map of the World: Australia and Oceania, Sheets 9 and 13, 1971

New Zealand Geological Survey

(Institute of Geological and Nuclear Sciences, Limited)

Scale 1:5,000,000

The following process steps were taken:

        1.  Gray-scale scanned images of the source maps were registered and rectified in

Arc/Info.  In the case of the UNESCO maps, they were registered to a composite of

Arcworld country boundaries (shorelines) and Arcworld water bodies projected to a

Lambert projection with standard parallels of 40 and 10 degrees North, and a central

meridian of 70 degrees East, with an average root mean square error of 600 meters.

In the case of the Australia and New Zealand maps they were registered to a grid

of latitude and longitude lines generated as an arc coverage in Arc/Info and projected

to the appropriate Lambert parameters for each map sheet, with an average root mean

square error of 350 meters..

3.

 



Geologic contacts were then digitized on screen in Arcedit using the scanned

gray-scale images as a backdrop.  Labels were applied and attributed as the linework was

digitized using special AML menus and scripts.

In the case of Australia and New Zealand, the coverage being digitized was re-projected to

match the projection of each source map sheet.  The original geologic attribution was

generalized using reselect and calculate functions in Arcedit.

        4.  Because of contradictions in compilation, the digitized coverages were then

transformed with a series of piece wise "rubber sheet" adjustments.  The composite

Arcworld coverage was used for transformation because it is derived from a readily

obtainable standard compiled on a worldwide basis.

        5.  The coverages comprising the three plates of this Open-File Report were projected

to optimal Lambert projections for these particular geographic regions.

        6.  The map sheets were produced in Arcplot using AML scripts.  The geologic legend

was generated as a separate graphic file in Arcplot.  The Adobe Portable Document Format

was created with postscript files generated in Arcplot.

ABOUT THIS MAP

This digitally compiled map is part of a worldwide series of maps on CD−ROM released by the U.S. Geological Survey‘s

World Energy Project. The goal of the project is to assess the undiscovered, technically recoverable oil and gas

resources of the world.  For data management purposes, the world was divided into eight energy regions based on

political boundaries and corresponding approximately to the economic regions of the world as defined by the U.S.

Department of State.  This map covers the northern portion of the Asia Pacific Region (Region 3) and includes the People‘s

Republic of China, Japan, North and South Korea and Mongolia, and parts of Cambodia, Laos, Thailand and Vietnam.  Two

additional maps of the Asia Pacific Region cover Southeast Asia (Plate 2) and Australia and New Zealand (Plate 3) both to the south.

The region is divided into geologic provinces.  Each province has a set of geologic characteristics that distinguish it

from surrounding provinces.  These characteristics may include the predominant lithologies, the age of the strata,

and the structural style.  Some provinces include multiple genetically−related basins.  Klett and others (1997) list all

by the 2000 meter bathymetric contour.  Each province is assigned a unique number.  Because geological trends are independent

of political boundaries, some provinces overlap two regions and two or more countries.  Those provinces that lie entirely within

the Asia Pacific Region begin with the number 3.  Those provinces that lie partly within another region may start with a 1,

for the Former Soviet Union, or an 8 for South Asia.  For the sake of clarity province names are not included on this plate.

Details of the data sources and map compilation are given in the metadata file on CD−ROM and at the lower left of

this map.  The geologic outcrops on this map are based primarily on the Geologic Map of South and East Asia by Ghose

and others (1990), used with permission.  Some stratigraphic units are combined to simplify the map and to ensure consistency

across the region.  All rocks are colored by age.  Sedimentary and metamorphic rocks are not differentiated, whereas igneous

rocks and their types are indicated by patterns superimposed on the appropriate age color. The centerpoint locations of oil

and gas fields are plotted based on the locations in the Petroconsultants database (1996) and are used with permission.

This map is compiled using Environmental Systems Research Institute, Inc. (ESRI) ARC/INFO software.  Political boundaries and

cartographic representations on this map are taken, with permission, from ESRI (1992), they have no political significance and

Details of the data sources and map compilations are given in the metadata file on the CD−ROM and below.  The geologic outcrops on this map are

based primarily on the Geological Map of South and East Asia by Ghose and others, 1990, and on the Geological Map of the World: Australia and Oceania

by the Bureau of Mineral Resources (now Australian Geological Survey Organisation), 1965 and 1967.  Some stratigraphic units are combined to simplify

the map and to ensure consistency across the region. All rocks are colored by age. Sedimentary and metamorphic rocks are not differentiated, whereas

igneous rocks and their types are indicated by patterns superimposed on the appropriate age color. The centerpoints of oil and gas fields are plotted

based on the locations in the Petroconsultants database (1996) and are used with permission.

This map is compiled using Environmental Systems Research Institute Inc. (ESRI) ARC/INFO software.  Political boundaries and cartographic

representation on this map are taken, with permission, from ESRI (1992), they have no political significance and are displayed as general reference

ABOUT THIS MAP

This digitally compiled map is part of a worldwide series of maps on CD−ROM released by the U.S. Geological Survey‘s World

World Energy Project.  The goal of the project is to assess the undiscovered, technically recoverable oil and gas resources

of the world.  For data management purposes, the world is divided into eight regions based on political boundaries, and

corresponding approximately to the economic regions of the world as defined by be U.S. Department of State.  This map covers

the southern part of the Asia Pacific Region (Region 3) and includes Australia, Fiji, New Caledonia, New Zealand, Tonga and Vanuatu.

Two additional maps of the Asia Pacific Region cover the Far East (Plate 1) and Southeast Asia (Plate 2) both to the north.

The region is divided into geologic provinces. Each province has a set of geologic characteristics that distinguish it from

surrounding provinces.  These characteristics may include the predominant lithologies, the age of the strata and the structural

style.  Some provinces contain multiple genetically−related basins. Klett and others, (1997) list all the provinces identified by

the World Energy Project and rank them by known petroleum volumes. Offshore province boundaries are defined by the 2000 meter contour.

Each province is assigned a unique number that begins with region number (3). Details of the map sources and compilation are

given in the metadata file on the CD−ROM and at the lower left of this map.  The geologic outcrops on this map are based primarily

on the Geological Map of the World: Australia and Oceania by the Bureau of Mineral Resources (now Australian Geological Survey

Organisation)(1965 and 1967) and the New Zealand Geological Survey (Institute of Geological and Nuclear Sciences Limited)(c)(1971).

Some stratigraphic units are combined to simplify the map and to ensure consistency across the region.  All rocks are colored by age.

Sedimentary and metamorphic rocks are not differentiated whereas igneous rocks and their types are indicated by patterns superimposed

on the appropriate age color. The centerpoint locations of oil and gas fields are plotted based on the locations in the Petroconsultants

database (1996) with their permission.

This map is compiled using Environmental Systems Research Institute, Inc. (ESRI) Arc/Info software.  Political boundaries

and cartographic representations on this map are taken, with permission, from ESRI (1992); they have no political significance and

are displayed as a general reference only.  Portions of this database covering the coastlines and country boundaries contain
