摘要

<正>Objective Spherical micro-particles are often preserved in Precambrian sedimentary rocks.Finnish and Chinese scholars have previously discovered carbonaceous,siliceous or ferruginous spherules of out-space origin in the 1.6 Ga and 1.4 Ga sequence,respectively.The presence of spherules can record possible cosmic impact events.Also,cosmic spherules provide important information on the evolution of planets from outer space.This work firstly discovered cosmic spherules in thin layer of carbonaceous siltstone from the Taizi Fm.(1.2-1.3 Ga)of the Shennongjia group in the Shennongjia area,Hubei
