The Amazon area is mostly found within a large polygon marked by the division lines of each side of a single convection roll of lower mantle. The main hub of downwelling forms the esturary of the Amazon River, the largest river in the world. At the other side of the continent, the division line (wide red) between convection rolls does cross the Andes Mountains under the volcano Tuguruahua.
The polygon of Amazon area
The exact 30° span along equator from the trench in the east to the estuary in the west is an outstanding manifestation of the predicted interval between convection rolls of the lower mantle.
Indonesia covers 30° along equator from east to west, and the end points happen to be the locations of main convection rolls division lines. Tracing the western division line further south, it leads to the most active volcano of Indonesia, Mount Merapi.
Mount Merapi is located over main division line of lower mantle convection rolls.
This indicates an interplay between the subduction of crust material and the mantle convection activity. The few facts shown on the map, a span of 30° along equator and the location of Merapi, already give us some insight into the geology of Indonesia. By further analyzing the effect of upper convection rolls (with 1.5° interval) much more will be revealed about the real nature of volcanism, geothermal activity and the tectonic framework in general.
The Icelandic Plateau is elliptical and can be drawn accurately with a definite central point. Expanding the ellipse towards the Jan Mayen Fracture Zones, it overlaps them. Expanding further, an ellipse with same NS-axis meets with the West Coast of both Norway and Greenland. The same structure shows consistency with Greenland-Iceland Ridge and Iceland Faroe Ridge. To describe the details accurately would take many pages, but everyone can have a short look at this map, saying as much as thousand words:
Large Scals Symmetry between Norway and Greenland.
Of course this is no coincidence, because of the large scale convection rolls found underneath the North Atlantic Ocean. The main division line between those convection rolls is found near, and parallel to, the central axis of the Reykjanes Ridge. The fact that Ægir Ridge became inactive, leaving a slice of East Greenland where Jan Mayen is found today, did lead to the special result that the West Coast of Norway and West Coast of Greenland match within this framework. The symmetry found along certain latitudes is due to the effect of Earth’s rotation, and the correspondatly regular formation of mantle convection rolls.
As some aspects can be seen clearer in context with the convection rolls model, another map is added hear with similar information:
Symmetry compared with mantle convection rolls system
Along 64°N, the most obvious symmetry is the 60° interval between West Greenland and West Norway, with central point exactly where the two convection rolls division line passes through Iceland. The other central focus of Iceland is where the two ridges would meet if they were continued on the surface. That is the central point of the Large Icelandic Plateau, and also the central point for an elliptical form that fits with Jan Mayen Fracture Zone, and thereby the end point of the Kolbeinsey Ridge (KR). It also marks the end of the Ægir Ridge. Large scale polygons seem to be affecting the locations of termination of all the ridges.
The location and alignment of the Reykjanes Ridge is consistent with both older and newer volcanic areas of Iceland. It can be shown that five parallel areas of volcanic activity have developed durning the last 24 million years. Moreover, they follow the model of convection rolls closely:
Timing of volcanic activity in Iceland
The timing is marked in the map according to this table:
This regularity forms a base for us for realizing the real nature of what we call ‘rift jump’. Also, it shows that the convection rolls under the country marked with wide red lines are quite dominant when it comes to volcanic activity and rift process. Nature is not simple, so the other layers underneath also affect the surface. Therefore, to fully analyze the formation of Reykjanes Ridge, the related volcanic zones and volcanic belts, the whole pattern of convection rolls has to be taken into account. Remember that the wide, red lines are upwelling lines. In between, there is one line (thinner) that is downwelling. Thereby you can visualize the scope of each convection roll extending NE-SW (at 120 km depth). When more familiar with the system, you can also visualize the lower layers with additional convection rolls.
The rift zone ´jumps´ in Iceland are well known, occurring every 7 million years or so. The central axis of these zones have been mapped, and the regularity of interval between them can be detected easily. One volcanic zone has hitherto not been included, because it is not a rift zone. All the same, it fits into the pattern of regularity. The wide red lines are upwelling division lines between uppermost convection rolls. These rolls interact with the tectonic plate at the depth of 120 km.
Five equally distributed volcanic zones
The NW rift axis and the Snæfellsnes-Húnaflói rift axis are extinct, but Reykjanes Ridge and the Eastern rift axis are active. Öræfajökull is found on the fifth line.
