| Abstract |
In order to figure out the sedimentary environments of contourites of two areas in northern Hunan, we test trace elements in all the 43 samples taken from them. The results show that during the Early Ordovician, Jiuxi area was a platform slope zone which was in a hot, dry, high-salinity and reducing environment. Yuanguping area was a transition zone between the slope (the slope was in a hot, humid, ungated and weak-reducing environment) and the basin. |
