That startling picture emerges from a study published this month in Earth and Planetary Science Letters by a team led by Paulo Vasconcelos, a geochemist at the University of Queensland in Brisbane, Australia. Until recently, scientists could estimate erosion only by looking at the sediment sloughed off of a surface. But new geochemical tools developed by, among others, Vasconcelos and his colleagues measure erosion from rock that's left behind. Earth scientists say ancient landscapes could exist atop other inselbergs, a German term for the isolated plateaus that dot geologically quiet regions in the Southern Hemisphere that have not been reshaped by plate tectonics or planed away by ice sheets.
Geologists had suspected that these inselbergs, found in Brazil, Australia, and southern Africa, are old—enduring while erosion stripped away the surrounding landscape. Now, that history is emerging. For decades, geomorphologists have fixated on regions where plate tectonics accelerates geologic change, thrusting up mountains, opening rifts, and creating traps for oil and gas.
Or to oil. Vasconcelos and his team used four different geochemical dating systems to flesh out the story of the Urucum plateau and its neighbor, the Santa Cruz. One took advantage of grains of the mineral manganese oxide that formed when the surface was first exposed to rain. The grains incorporated trace amounts of radioactive potassium, which has steadily decayed into argon ever since, providing a clock that shows the landscape formed 60 million to 70 million years ago. Another gauge of erosion comes from a set of isotopes—of helium, beryllium, and aluminum—that form when cosmic rays bombard surface rocks.
The high abundances of these isotopes suggest the plateaus shed only 1 meter of material every 10 million years; the surrounding landscape, meanwhile, likely eroded at times that rate, the group concludes. The results raise a new question, says Jane Willenbring, a geomorphologist at the Scripps Institution of Oceanography in San Diego, California: "What makes landscapes persist for millions of years?
