2005-12-01 · During the Phanerozoic, volcanic passive margins are thought to be associated with an average accretion rate of 0.4 km 3 yr −1 of new igneous transitional crust . This can be compared to the upper-bound estimate of ca 1 km 3 yr −1 for the global rate of continental crust accretion at the same period [69] .

Examples of passive margins are the Atlantic and Gulf coastal regions which represent setting where thick accumulations of sedimentary materials have buried ancient rifted continental boundaries formed by the opening of the Atlantic Ocean basin. The Atlantic Coast of the United States is characterized by wide beaches, barrier islands, broad

The distribution of known volcanic margins is shown on the graphic to the right. Many of the margins have not been thoroughly investigated and more passive margins are identified as volcanic from time to time. Volcanic passive margins: South Atlantic; Western Australia; Southwest India; West Greenland; East Greenland For example: (1) deep seismic observations and deep sea drilling have revealed more of the diversity of passive margins geodynamics. This liberates explorationists from simple geodynamic models, with consequences not only for new views of thermal history but also for the whole tectonic and stratigraphic evolution. For Volcanic passive margin Volcanic passive margins (VPM) and non-volcanic passive margins are the two forms of transitional crust that lie beneath passive continental margins that occur on Earth as the result of the formation of ocean basins via continental rifting . An excellent example is the west coast of South America. Active margins are commonly the sites of tectonic activity: earthquakes, volcanoes, mountain building, and the formation of new igneous rock.

Volcanic passive margins: South Atlantic; Western Australia; Southwest India; West Greenland; East Greenland hard areas (magma-poor margins). Transitional margins, with characteristics of both end-members, develop when the soft points approach the hard points. In the South Atlantic Ocean, the Pelotas Basin is a typical volcanic passive margin while the Santos, Campos and Espírito Santo Basins are examples of magma-poor passive margins.
