| Abstract: | Cambrian biostratigraphic data of the Tarim Basin are chiefly from outcrops.This paper reports the latest advances in Cambrian biostratigraphic research of the Tarim Basin based on data from 11 SINOPEC wells and the CNPC Kunan 1 well.From the borehole samples,we have recovered 15 groups of Cambrian microfossils,including 58 genera and 73 species of small shelly fossils and conodonts,as well as 29 genera and 30 species of organic-walled microfossils.These fossils include hyoliths(e.g.Paragloborites,Circotheca,Torellella),bivalves(e.g.Praelomellodonta),gastropods(e.g.Barskovia,Auriculaspira,Scenella),disarticulated sclerites(e.g.Zhijinites,Sachites),Chancelloria,sponges(e.g.Zhejiangorhabdion),Aegides,and trace fossils.Combined biostratigraphic,lithostratigraphic,well log,and seismic stratigraphic data can be used to correlate the Cambrian strata in the Tarim Basin with those in East Yunnan of the lower Yangtze region and in Kazakhstan. |
