PETROGENESIS OF PILLOW BASALTS IN WEST JUNGGAR, NW CHINA:CONSTRAINTS FROM GEOCHRONOLOGY, GEOCHEMISTRY, AND SR–ND–PB ISOTOPES
West Junggar, Northwest China includes silurian pillow basalts of the
Mayilashan Formation
Petrogenesis of pillow basalt samples
Petrogenesis of these rocks are important for the understanding of the tectonic evolution of the area
What is the origin, chronology, and chemical composition of pillow basalts in West Junggar?
Geochronologicalanalysis
Geochemicalanalysis
Sr–Nd–Pb isotope analysis
Central Asian Orogenic Belt
These characteristics indicate that the magmas were derived from a deep OIB reservoir

Zircon dating
Dupal‐like isotopic signature of the crust of the southern Paleo‐Asian
Ocean
Sr-Nd-Pb isotope analysis
Chemical signature of ocean island basalt (OIB), which is alkaline, rich in light rare earth
elements, and deficient in heavyrare earth elements
