"We present a detailed, new time scale for an orogenic cycle (oceanic accretion-subduction-collision) that provides significant insights into Paleozoic continental growth processes in the southeastern segment of the long-lived Central Asian Orogenic Belt (CAOB). The most prominent tectonic feature in Inner Mongolia is the association of paired orogens," investigators in Beijing, People's Republic of China report. "A southern orogen forms a typical are-trench complex, in which a supra-subduction zone ophiolite records successive phases during its life cycle: birth (ca. 497-477 Ma), when the ocean floor of the ophiolite was formed; (2) youth (ca. 473-470 Ma), characterized...
