| Abstract: | U-Pb dating for radiolarite and gabbro indicates that the Runiange Formation should be formed during Middle Triassic Latin and Late Triassic Norian Stage. Discovery of ophiolite in the Runiange Formation indicates that the Luohuo-Dawu structure zone underwent initial ocean basin stage. |

| Keywords: | Runiange Formation Luhuo-Dawu tectonic melange zone ophiolite initial ocean basin |
