摘要：

新疆西准噶尔沙尔布尔提山晚志留世、早泥盆世孢子和疑源类包括孢子21属31种和变种,其中新种1个(Amicosporites xinjiangensis);疑源类11属14种。此外还有几丁虫3属3种。根据孢子在地层中分布规律和演化特征,自下而上可划出4个孢子带:1.Synorisporites dittonensis—Api-culiretusispora spicula(DS)带;2.Emphanisporites micrornatus—Streelispora newportensis(MN)带;3.Chelinospora cassicula—Perotriletes subitus(CS)带;4.Grandispora sp.—Apiculatasporites micro-conus(CM)带;上述孢子组合基本上可与中国华南、西南、西秦岭及有关国家、地区相同时代孢子带对比。根据孢子和疑源类材料,对西准噶尔志留—泥盆系界线、古地理和古生态进行了讨论。
