| 英文摘要 | The intrusive complex in the Fanshan, Hebei province, China, consisting of layered patassic alkaline ultramafite and alkaline syenite, is know in the world for its containing large magnetite apatite deposits, and the rocks and deposits have been investigated and a lot of data have been accumulated over the past twenty years. However, their formation timing is still in dispute. Most geologists consider that the rocks and deposits in the Fanshan intrusive complex originated in Triassic Period between 250Ma and 200Ma., but some believe that they were formed in Permian Period. Sm-Nd dating of the Fanshan intrusive complex has been performed, and its age have been obtained. The Sm-Nd isochron age of four mineral samples and two whole rock samples from the Fanshan intrusive complex is 243. 4 +/-9.7Ma with I-Nd = 0.512045, epsilon (Nd) (t) = - 5.4, and the Sm-Nd isochron age of four mineral samples and seven whole rock samples from the Fanshan intrusive complex is 239 +/- 19Ma with I-Nd = 0.512055, epsilon (Nd) (t) = - 5.3 These age data indicate that emplacement of the Fanshan complex started at early Triassic period. However, the Rb-Sr isochron age in the Fanshan complex is 218 +/- 8Ma with I-Sr 0.70554, epsilon (Sr) = 18.4, suggesting possibly that the Fanshan complex was solidified completely in the middle Triassic Period. The Sr, Nd isotope fact of the Fanshan complex above shows that the Fanshan complex was derived from enriched mantle materials. |
