| Abstract: | Maliya ophiolite suite spreads within the 'nappes' between Karamay-Urh fault and Darbut fault. The ophiolite suite has all types of rocks and almost complete sequence, with it's own characters of petrology, petrochemistry, rare metal distribution, Sr isotopic ratio. The ophiolite represents the active marginal sea at the continental side of island arc or the tectonic setting of the basin between island arcs, being the products of diapir rising flow of the mantle material. The emplacement age is the Early-Middle Carboniferous. |
