| 摘 要： | Samples were collected f5rom the Selong-Xishan Permian/Triassic boundary strata,Nyalam County in southern Tibet and systematically analyzed for their rare-earth elements(REE) and trace elements such as U,Th,Sr,Ba,Sc,Ta,Hf,Rb,Cs,Co,Ni,Cr,As and others with emphasis put on the distribution patterns of rare-earth elements and the variation of trace element contents along the Permial/Triassic boundary section.On this basis a discussion will be made of the paleo-ocean depositional environment. |

| Abstract: | Samples were collected from the Selong-Xishan Permian/Triassic boundary strata, Nyalam County in southern Tibet and systematically analyzed for their rare-earth elements (REE)and trace elements such as U, Th, Sr, Ba, Sc, Ta, Hf, Rb, Cs, Co, Ni, Cr, As and others with emphasis put on the distribution patterns of rare-earth elements and the variation of trace element contents along the Permian/Triassic boundary section. On this basis a discussion will be made of the paleo-ocean depositional environment. |
