At this location, both plates consist of oceanic lithosphere. At the plate boundary, the Pacific Plate is forced under the North America Plate to form the Aleutian Trench and a subduction zone. A diagram of this plate boundary situation is shown in the simplified cross-section on this page.Pa...
The characteristics of submarine Fe–Mn oxide are depicted here in a geochemical ternary diagram24. Most samples plot within the hydrothermal origin field; however, the rimmed samples lie between the hydrothermal and intermediate hydrogenetic and diagenetic fields (Fig. 5). Because Fe–Mn crusts gr...
Pie diagram shows the relative abundance of each mineral. Symbols are explained in the figure. Potassic alteration in the Siah Diq prospect is either not very well developed or the actual intense potassic zone lies farther toward the north of the drilling site in the intense geophysical anomalies...

Volcano - Plate Boundaries, Magma, Eruptions: Topographic maps reveal the locations of large earthquakes and indicate the boundaries of the 12 major tectonic plates. For example, the Pacific Plate is bounded by the earthquake zones of New Zealand, New Gu
crustal generation and destruction Three-dimensional diagram showing crustal generation and destruction according to the theory of plate tectonics; included are the three kinds of plate boundaries—divergent, convergent (or collision), and strike-slip (or transform). (more) subduction zone geology As...
Earth’stectonic plates, which move horizontally with respect to one another at a rate of a few centimetres per year, form three basic types of boundaries:convergent,divergent, andside-slipping. Japan and the Aleutian Islands are located on convergent boundaries where the Pacific Plate is moving ...
