This digitally compiled map includes geology, oil and gas field
centerpoints, geologic provinces, and major faults of Iran with some of
these components extended into geographically adjacent areas. This digital
compilation is an interim product of the U.S. Geological Survey's World
Energy Project (WEP) and part of a series on CD-ROM. The goal of the WEP is
to assess the undiscovered, technically recoverable oil and gas resources
of the world and report the result of this assessment in 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.
Each world energy region was then further divided into geologic provinces
on the basis of natural geologic entities and may include a dominant
geologic structural element or a number of contiguous elements. Some
provinces contain multiple, genetically related basins.
Geologic province boundaries for Iran were delineated using data from
different geologic maps, publications, and other tectonic and geographic
data. Each province was assigned a unique number; the first digit is the
region number. An attempt was made to number the provinces in geographical
order or groups (see Pollastro and others, 1998). The list of provinces
sorted by number is shown to the right of the map.
Centerpoints of oil and gas fields are shown and were plotted with
permission from Petroconsultants International Data Corporation, 1996
worldwide oil and gas field database.
Allocation of field data to geologic provinces provided a ranking of the
provinces by total known petroleum volume (see Klett and others, 1997). The
WEP further characterizes the geologic provinces by petroleum system and
assessment units in order to assess the undiscovered petroleum volume.
Specific details of map and data sources, and the procedure used in the
compilation of this geologic map of Iran are given in the metadata files
and described briefly in the text below.
Stratigraphic subdivisions of Phanerozoic rocks were combined to simplify
the geology and maintain consistency with other maps in this series.
Precambrian rocks are undivided.
This map was compiled using Environmental Systems Research Institute, Inc.
(ESRI) ARC/INFO software. Political boundaries and cartographic
representations are used, with permission, from ESRI's ArcWorld 1:3M
digital coverages, have no political significance, and are displayed for
general reference only.

SCIENTIFIC REPORT
TROUBLESHOOTING
This Arcview project was developed in Arcview 3.0. When opened in Arcview 3.1 there
may be a message asking whether to upgrade to 3.1 tools. It is suggested that the
user respond no. There will still be tools and buttons not intended in the original
project, but they have no impact on the functionality of the project.
If a "segmentation violation" occurs when using the zoom or pan tools, it is an indication that the Univers Medium font is not present on your computer. Suggested solutions are either to install the font, create a new project with the shapefiles and shadesets provided, or the copy the project and alter the avenue scripts to use a font that is present for labeling cities and geologic age.
Also it has been noted that on occassion an ArcView Project file will open up with
a "blank" view. It is suggested to go back to the "project" window and reopen the
desired view. Also one may need to make adjustments to the size of the windows.
If pdf files do not display properly 1) allocate more memory to the Reader application
if possible, 2) open up the pdf file from within the Reader application.
It has been observed that jpeg files within MS Internet Explorer do not always display
properly. One may need to use other software to display jpeg files.
With Windows NT 4 when executing ArcExplorer from the Readme.htm file there is an
inconsistency in finding the correct project files. It is suggested to quit and try again.
"Autostart" is invoked for Windows and Macintosh platforms when a CD is initially put in the
computer. An internet browser should open the Readme.htm file. If this does not happen
the facility to use "autostart" may be turned off. Macintosh must change a setting within
the Quicktime Settings Control Panel. Windows users must have Auto Insert Notification (AIN)
on for AutoPlay to work. Alternatively, users can open the root level "readme.htm" file by
double-clicking the icon or opening the file from within a browser.
