Question

Tectonism is ubiquitous on Earth, the fundamental process responsible for the terrains we find familiar. In this exercise, you will visit a series of locations where distinctive geologic structures are exposed by geologic processes. Your task will be to identify these structures as best you can @eaglo Fig. 1. Google Earth image a transform fault in Montana In Google Earth, use the coordinates below to locate a variety of structures. This week the structures of interest are all faults. There are normal faults, reverse faults, and strike-slip faults (right and left lateral). Inspect each fault and try to determine the sense of offset.

Explanation / Answer

ANSWER:

Catastrophic plate tectonics seems to be sped-up plate tectonics, a paradigm assumed too quickly and with many uniformitarian assumptions, including ‘precise’ radiometric and fossil dates. New geophysical data sets on subduction zones are contrary to plate tectonic expectations and indicate that subduction is unlikely. Without subduction, plate tectonics and catastrophic plate tectonics is impossible, unless the Earth expands. A cursory description of some of the many other problems associated with plate tectonics is provided. These problems should generally apply to catastrophic plate tectonics. A few unique problems are associated with catastrophic plate tectonics, such as excess heat caused by sliding plates and lava resurfacing, Wilson cycles, and copious post-Flood catastrophism as the ocean-bottom lava cools over a few hundred years. Although I do not need to provide an alternative mechanism in this forum, I lean toward the hypothesis of vertical tectonics, possibly combined with meteorite impacts.

The catastrophic plate tectonics model of Austin et al. is a sophisticated Flood model that deserves much attention.  am impressed with all the hard computer modeling work by John Baumgardner. I commend the authors involved in this model for all their effort.

However, I have a number of problems with the model. In this initial presentation of a catastrophic plate tectonics forum, I will state the philosophical problem of borrowing so many uniformitarian deductions from plate tectonics. Then I will briefly mention evidence from new geophysical data sets that subduction is unlikely. This information in more detail has been published elsewhere.Without subduction, plate tectonics is impossible unless the Earth expands. I will give a very cursory description of some of the many other problems associated with plate tectonics, which should generally apply to catastrophic plate tectonics. A few unique problems with catastrophic plate tectonics will be brought to the attention of the readers. It is preferable to be able to provide an alternative model, which is briefly introduced in the final section.
