Passive margins Cased of continental margins that are well within the interiors of a plate and far away from plate margins. Most continental margins around the Atlantic are passive. Key characteristics of passive continental margins includes the absence of volcanoes and much earthquake activity,


The variation in focal mechanisms across the margin suggests a spatially varying stress field. Although the later feature may not be a general characteristic, the empiricism that passive margin seismicity seems most evident on recently deglaciated margins suggests that deglaciation is at least partially responsible for the earthquakes.

Operating margin measures the profit a company makes on a dollar of sales after accounting for the direct costs involved in earning those revenues.

Previous models of subduction initiation (SI) at passive margins generally ignore effects due to the lateral transition from oceanic to continental lithosphere. Here, we use three-dimensional numerical models to study the possibility Passive margins are distinguished worldwide into two denominations (Sawyer et al., 1997): (1) So-called "magma-rich" or "volcanic" margins would present specific characteristic such as Seaward The Convergent Margins thematic had multiple objectives: The main one was about research and renewal of our understanding of convergent margins, taking into account the impact of the deep Lithosphere, asthenosphere evolution on the history of architecture, deformation, thermal evolutions, including fluid/rocks interactions, surface dynamics, sedimentary routing system and deposits.
