| Abstract: | The sequences and structures of the early and late Ordovician ophiolite strata in the north Qilian Mountains are expounded and proved in accordance with the data derived from petrology, petrochemistry, rare elements etc.and correlated with the typical ophiolite strata sequences.It is considered that the both ophiolitic suites are of the stratal configuration and the features of the complexes accumulational lava and the abyssal sediments composed of ultramafite, mafite and leucolith rocks. |
