疑源類

ARENIGIAN ACRITARCHS FROM THE CHAOCHIAPA FORMATION OF? NINGQIANG COUNTY, SHAANXI PROVINCE?? 陜西寧強趙家壩組阿倫尼克期疑源類

Recorded herein are 197 species of 90 genera of spores and pollen and 4 species of 2 genera of fossil algae and 2 species of 2 genera of acritarchs. 建立三疊紀的孢粉組合序列（5個組合、2個亞組合），并詳細地討論各個組合的地質(zhì)時代。

The acritarch assemblage available can be used fur biostratigraphic correlation of the Qingbaikou System in the vast Yanshan region, North China. 以上疑源類的穩(wěn)定性和可比性，可作為具有廣泛生物地層對比依據(jù)。

A moderately abundant and diverse acritarch assemblage was recovered from the Miaopo Formation at 4 sections in Yichang area, Hubei, South China. 湖北宜昌地區(qū)廟坡組是達瑞威爾階/桑比階界線附近的地層,該段地層產(chǎn)出分異度較高,豐度適中的疑源類組合。
