Thrust-faulted areas

If all the ocean crust is Jurassic, or younger, there’s a lot happening here onshore that is never preserved out there. It’s difficult to compare the two.” Anita said, “I believe in plate tectonics-just not in the way they’re perpetrating it for places like the East Coast. It shouldn’t be used as the immediate answer to every problem. That’s what I object to. Now that their suture zones have disappeared, people are going to microplates.” “They seem to be saying that you don’t have to see any order,” Leonard said. “Because it’s all chaos, and if it’s chaos why worry about it?” ‘What we try to do is pull the thrust plates apart and make them into some sort of recognizable geologic model,” Anita said. Leonard said, “You pull something apart to see what it might have been, not what you think it was in advance. It might have been a shelf, a basin. You work at it, and see what it was.” “The plate-tectonics boys conference room amsterdam make no attempt to do this, because they see no reason to,” Anita said. “There are too many pieces missing. Each existing piece is an entity unto itself. Everything is random pieces.” “Most people have never had an opportunity to work with thrust-faulted areas. We’ve lived with them all our lives. If we go along a fault system far enough, we can actually see the next thrust plate. Maybe I’ll have to go a hundred miles until I find out what it really looked like. You do that by making a model. You pull the thrusts apart and see what the country originally looked like. But until you’ve done that, and been faced with that problem, it’s natural to say, ‘God, these are so different. They could be conference room amsterdam zuidas microcontinents.’ You can reconstruct a large Rat piece out to the east as an original depositional basin. You can see volcanic terrane that was partly onshore, partly offshore. You can look at that as a basin, too, just sitting there, a continuous thing. You see the same thing from Georgia north. The Appalachian belts are almost continuous basins, showing different kinds of depositional patterns. They’re not exotic pieces.” “Not at all.” “Science is not a detached, impersonal thing. People will be influenced as much by someone who is a spellbinder as by someone with a good, logical story. It is spellbinding to say that these belts are exotic and were built through time by micro or macro pieces aggregated to the continent. But the fact that you’ve got seismic lines without any apparent suture lines makes you wonder what really happened. Where are those Devonian and Taconic sutures? Are they just not being recognized? Or are they in fact thrust plates?”
