Geochronology and geochemistry of the Manxin ophiolitic mélange in the Changning‐Menglian Suture Zone, southwest China: Implications for the tectonic evolution of the Proto‐Tethys Ocean

Abstract

To date, the evolutionary history of the Proto-Tethys Ocean that separated the Gondwana and Laurasia continents remains ambiguous. The Changning-Menglian Suture Zone assumingly represents the Proto-and Palaeo-Tethys suture in the Sanjiang area (the Yunnan Province, southwestern China). The Palaeozoic Proto-Tethys
