| 英文摘要 | Ordovician cherts, mudstone, greywacke, calearenite, bioclastic limestone, reef limestone and alkaline basalts, ignimbrite, pyroclastic rocks represent the lithological associations of a seamount/oceanic island in the Shihuigou, North Qilian orogenic belt. The cherts contain abundant early-middle Ordovician conodonts, and mudstone and sandstone contain middle-late Ordovician Trilobita and graptolite fossils. Geochemical analysis of these chert samples indicates that they contain some detrital components from source area with distinctive character of LREE enrichment and negative Eu(CN) anomalous; they deposited in the continental margin rather than in the open sea or near the spreading ridge setting. |
