Specialists in this new field have recognized more than 300 different terranes around the margins of the Pacific. In keeping with this spirit, this article quotes a perceptive Old Geologist's Saying: "I wouldn't have seen it if I hadn't believed it."

Science Frontiers ONLINE No. 57: May-Jun 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Florida More Exotic Than The Travel Agents Promise Anyone who has visited Florida knows that it differs in several ways from the rest of North America. Now we find that Florida doesn't even belong to North America; it is an interloper, an "exotic terrane." How does one know this? Three facts hint that Florida doesn't belong: When pre-Cenozoic land masses are fitted together, assuming the truth of continental drift, an awkward overlap arises that suggests that Florida was not always where it is today; The latest paleomagnetic measurement of Florida's Paleozoic latitude is consistent with it being part of Gond wanaland rather than at its present latitude; Radiometric dating of zircons retrieved from a core extracted from Northern Florica yield an age of 16501800 million years. There are no known source rocks in the southeastern U.S . that old; Africa and South America are likely sources of such zircons. "These (latter) two new lines of geologic data provide strong evidence confirming previous suggestions that Florida was part of Gondwana during the early Paleozoic and that its current configuration is that of an exotic terrane sutured to North America during the fragmentation of Pangea." (Opdyke, Neil D., et al; "Florida as an Exotic Terrane: Paleomagnetic and Geochronologic Investigation of Lower Paleozoic Rocks from the Subsurface of Florida," Geology , 15:900, 1987.) Comment. Other exotic terranes have been ...

... Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Slice Of Ocean Crust In Wyoming Tucked among Wyoming's Wind River Mountains is a region of exotic crustal rocks. The best explanation conventional geology has come up with is that they were formed some 2.5 billion years ago by geological processes not in operation today. G. Harper, however, thinks that these Wyoming rocks look very much like some of the slices of ocean crust (terranes) that continental drift's conveyor belt has plastered against North America's west coast. The conveyor belt is, of course, the ocean floor that dives under the continent. The more he looked, the more Harper was convinced that there, in the middle of the continent, was a substantial chunk of ancient ocean crust. The implications: continental drift and terrane plastering have been in operation for billions of years: ". .. from their very beginnings continents have been built up from the bits and pieces of plate tectonics." Some other geologists concur and point to similar rocks in northern Canada and around the Great Lakes. (Kerr, Richard A.; "Plate Tectonics Is the Key to the Distant Past," Science, 234:670, 1986.) Comment. If the continents have been slapped together in such a disorganized manner, have stratigraphy and geological dating been compromised? Reference.

Part of the state is grinding against Washington. But Oregonians will not get dizzy. The periphery moves only a few millimeters each year. (Anonymous; "In a Spin," New Scientist, p. 25, October 7, 2000. Source cited: Geophysical Research Letters, 27:3117, 2000.) Comment. Western Oregon is probably a "terrane" -- an exotic chunk of real estate that drifted in from somewhere in the Pacific and lodged up against the North American coastline. Nlany such terranes have piled up against western North America in the geological past. But what causes the differential rotation? From Science Frontiers #133, JAN-FEB 2001 . 2001 William R.

... make up southern Alaska, for example, started north of the equator 250 million years ago, crossed into the southern hemisphere, and started back north about 160 million years ago. However, the itinerary of northern Alaska cannot even be guessed at. Present thinking is that this portion of the state was close to the geographic north pole during the late Cretaceous. But this is the period when the huge coal deposits were formed on the Arctic slope. Much of this coal comes from evergreens, which could not have survived in high latitudes due to the lack of sunlight. So, the pieces of the puzzle are at hand, but their travels are a mystery.

... Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Moho Vicissitudes For a long time the Moho (Mohorovicic discontinuity) has been considered a stable plane dividing the crust from the mantle. It is at the Moho that seismic wave velocities change abruptly. There is something there, but no one knows just what. At the recent Second International Symposium on Deep Seismic Reflection Profiling of the Continental Lithosphere, a lot of doubts about the stability and character of the Moho surfaced. Under the North American Cordillera, which runs from Alaska to Mexico, the Moho is flat, continuous and oblivious to the faults, terrane plastering, mountain "roots," and the geological phenomena above it. In other areas, though, several Mohos are stacked up. Some Mohos are discontinuous, jumping from one depth to another. Others are strongly influenced by overhead geological structures. Gone is the neat, so simple Moho figured in all the textbooks. (Barton, Penny; "Deep Reflections on the Moho," Nature, 323:392, 1986.
