| Abstract: | A depositional formation distinctly different from the original Lower Carboniferous was found in
the east of the Baoshan Block and is termed the Zhangjiatian Formation.This formation is charaterized by
the presence of a lot of elastic rocks intercalated with two layers of altered basalt and yields abundant co
nodonts,which may be grouped into three blozones.Its age is of Early Carboniferous Yanguanian to
Datangian. |
