Abstract

Based on the research fruits of southeastern margin NNW trending on Ela Mountain magmatic belt, in Qaidam by predecessors, combing with the elements of formation age, environment, structure, thermodynamic, gravity and magnetic geophysical anomaly for volcano-magmatite, ophiolite and sedimentary strata, we consider that the Ela Mountain magmatic arc was the production taking Songpan-Ganzi plate with the suture of A'nyemaqen Ophiolitic Belt as the northward closure. During the whole closing period, there was slippage in the in the bottom, and the shallow before colliding was the pattern of peninsulas+Aulacogen+oceanic. The tectonic movement experienced three stages of oceanic crust subduction reduction, intracontinental collision orogenesis and crust extension. The granite of research area started from oceanic crust subduction, developed in intracontinental collision, so it had dual character of I-S type granite, which is the geologic record of the tectonic movement in late Hercynian to early Yanshanian. With deducing the development process, the authors divided the collision system of magmatic belt in the southeastern margin of the Qaidam.
- subduction,
- collisional orogeny,
- crustal extension,
- peninsula,
- aulacogen
