These special technical maps cover Magnetic and Gravity Anomaly. Gravity and magnetic anomalies show small departures from the expected values of the earth's gravity and magnetic fields caused by variations in the density and magnetisation of the rocks within the crust. The gravity map shows contour values as Bouger anomaly onshore, and free-air anomaly offshore. The magnetic map shows contours displayed as total field anomaly.

Geodynamic Map of the Mediterranean

1:13,000,000 - each sheet: 99cm x 53cm

This publication is the result of a new CGMW cartographic concept. The prime purpose of the Geodynamic map of the Mediterranean was to produce an updated synthetic picture of the current geodynamics of the region, compiled from several different and dishomogeneous data sets relevant to recent tectonics, to seismicity, kinematics, and volcanism. As a matter of fact, the Mediterranean region and surrounding areas are a key collisional region where the Nubia, Arabia, Somalia, and Eurasia lithospheric plates interact. The time period selected is relatively short, from 300,000 years to Present, covering the last two glacial maxima, and the intervening interglacial. Actually, it is assumed that the kinematic pattern of this period, inferred from geodetic measurements, remained stable but is nevertheless long enough for providing geological evidences of the activity of tectonic features.

Magnetic Anomaly Map of the World

1:50,000,000 - 100cm x 73.4cm

This map is the first global compilation of the wealth of magnetic anomaly information derived from more than 50 years of aeromagnetic surveys over land areas, research vessel magnetometer traverses at sea, and observations from Earth-orbiting satellites, supplemented by anomaly values derived from oceanic crustal ages. The objective is to provide an interpretive dimension to surface observations of the Earth’s composition and geologic structure. Metamorphism, petrology, and redox state all have important effects on the magnetism of crustal materials.

Map of the Indian Ocean

1:20,000,000 - each sheet: 111cm x 78cm

The two sheets (1- Physiography; 2- Structural) of this map are the first of the series of a new CGMW cartographic program devoted to the oceans of the World. The Indian Ocean map displays the main morphological and structural features of this region, covering both onshore and offshore areas and integrating the most recent data provided by marine magnetic profiling and global satellite altimetry.

Morpho-Bathymetry of the Mediterranean Sea

1:4,000,000 - 119cm x 85cm

This new map presents a complete view from the Gulf of Cadiz and western approaches of the Gibraltar Strait to the eastern shores of the Black Sea, and displays a contrasting view between the continental reliefs, in shades of grey, and the Mediterranean seafloor morphology revealed by a well-suited colour grading scale.

Seismotectonic Map of the Middle East

1:5,000,000 - 96.5cm x 76.5cm

This map was produced by the CGMW Subcommission for the Middle East and compiled by Dr. A. Haghipour of the Geological Survey of Iran as a contribution to the International Decade for Natural Disaster Reduction. It covers a particularly sensitive zone of our planet from the seismic point of view. On a geotectonic base, 1013 major historical earthquakes are plotted, ranging from the 3rd millennium B.C. to 1900 A.D., as well as 3029 teleseismic events of the 20th century, with a magnitude of 5 and over, and arranged according to magnitude and focal depth.

Sismotectonic Map of the World

1:50,000,00 - 118cm x 54cm

The Seismotectonic Map of the World is the result of a compilation of worldwide major seismic data spanning five millennia. Earthquakes are represented by groups of symbols classified according to their magnitude (= 6.0 on the Richter scale) or intensity (= VIII). This data has been plotted onto a continental and oceanic geostructural and neotectonic base map, together with data concerning plate kinematics, significant maximum horizontal stress orientations, and the main, recent and present-day active volcanoes.

World Stress Map + CD-ROM

1:46,000,000 - 120cm x 54cm

The World Stress Map (WSM) is the global compilation of information on the present-day tectonic stress field in the Earth's crust. It is a collaborative project, of University, Industry and Governmental organizations, that aims at understanding the sources of stress in the Earth's crust. The project was initiated in 1986 under the auspices of the International Lithosphere Program under the leadership of Mary Lou Zoback. Since 1995 the WSM is a research project of the Heidelberg Academy of Sciences and Humanities and is located at the Geophysical Institute of the University of Karlsruhe in Germany.
