Several geological data sets are present in the GEOID environment. These
data sets include a new tectonic map of the Middle East and North Africa
region which was developed by the Cornell Middle East and North Africa
group, a low resolution global geology map, a detailed geology map of the
United States, and additional data sets such as mine locations in the Middle
Eastern and North African countries, world stress map, and historically
active volcanoes of the world.
Several tectonic and geology maps in the Middle East and North Africa have been digitized and a uniform scale tectonic map of this region has been created. This data set includes features like faults, volcanics, basement outcrops, and ophiolites. Most features in the tectonic map have also been supplemented with related information, such as the activity of faults, detailed age information, etc. Figure 25 shows all the faults in the region. These data sets can be accessed through the "Tectonic Maps" button under the "Geological Data Sets", and then under the "Middle East and North Africa Tectonic Map" button (Figure 26). Using this menu, any of the tectonic features can be selected and displayed, and features in the map can be identified.
Mine locations of most of the Middle East and North African countries
have been entered into
the system (Figure
27). The data are organized by country and can be accessed through
the menu button available in the "Geological Data Sets" menu. Detailed
information exists for Algeria, Egypt, Iran, Iraq, Israel, Jordan, Libya,
Syria, Tunisia, Turkey, and Morocco mines. In addition, less detailed mine
locations from the USGS, DCW, and US Bureau of Mines sources have been
added. Figure 28
shows the producing mine locations in the Middle East and North Africa
region. Each of the locations are complete with attributes such as commodity,
mine type, activity, etc.
stress data compiled by several organizations have been recently made available.
We copied these data and placed them in GEOID with all their attributes.
This data set includes stress direction estimated from earthquakes focal
mechanisms, borehole measurements, and field data. This data set is available
through the "World Stress Map" button under the geology data sets (Figure
29). A small region in the southern Dead Sea fault is shown with available
stress measurements in Figure
volcano locations are a comprehensive list of historically active volcano
locations (Figure 31). This data set is available for the entire world.
The volcanoes data set can be accessed through the "Holocene Volcano Locations"
button. There are four different categories classified: Erupted between
1900 – 1993, Erupted 1 – 1900, Erupted B.C. and/or undated, and thermal
In addition to the data sets mentioned above there is a global geology
map of the world. This map has lower resolution information, and it should
be used with regional or continental scale applications. Figure
32 shows this data set.
The 1:2,500,000 scale US geology map is available through the geological
data sets option.
US Tectonic Map
Faults from 1:2,500,000 scale map is also available throught the geological
data sets option.
