Geologic signature of early Tertiary ridge subduction in Alaska
A mid-Paleocene to early Eocene encounter between an oceanic spreading center and a subduction zone produced a wide range of geologic features in Alaska. The most striking effects are seen in theExpand

Gold deposits of the northern margin of the North China Craton: multiple late Paleozoic–Mesozoic mineralizing events
Abstract. The northern margin of the North China craton is well-endowed with lode gold deposits hosting a resource of approximately 900 tonnes (t) of gold. The ~1,500-km-long region is characterizedExpand
