Hotspots, Plumes and
There were several interesting articles regarding
hotspots, plumes and volcanism which helped to bolster the position of my
theory. These include:
1. HOTSPOT MOVEMENT - Although the Standard
Theory says that hotspots extend from a fixed position way down in the mantle,
I contend that strong, young hotspots can move
in fact they are imbued
with motion by the pressure force of the impact. The article cited in Chapter
4.4 about Western Antarctica also speaks to the strange path of an Antarctic
hotspot trail that is not in sync with other hotspot trails on the same
continent. This out-of-sync hotspot trail is what I refer to as the antipodal
hotspot trail of the Kara impact 70 MYA., a hotspot that I would expect to have
its own separate direction of movement. I would point out that the Trinidad
hotspot to the east of South South America shows the same lack of congruity
with hotspot trails above and below it.
2. HOTSPOT MATERIAL - A study
of rocks from mid-ocean ridges and lava from hotspots shows that mid-ocean
ridge rocks are formed from lava near the top of the mantle, whereas the lava
from hotspots comes from deep in the mantle.
3. MANTLE PLUMES ARE
ROBUST - Recent tomography of the Earth shows that mantle plumes are broad,
robust and long-lived. These findings are in contrast to previous questions as
to whether mantle plumes even exist.
4. AUSTRALIAN HOTSPOT CHAIN -
Although I already cite a claim of hotspot volcanoes in Australia, it is nice
to see this chain confirmed by another source. My theory sees this chain as the
antipodal result of the Chesapeake Bay impact 35 MYA.
