摘　　要：本研究系统描述了中国东北那丹哈达地体中三叠系顶部和侏罗系下部的放射虫动物群及其系统分类,包括5个放射虫生物群,建立了一个新属,10个新种,并报道了121个种级分类单元。通过与加拿大和日本的相关动物群进行比较研究,我们确定了所描述的放射虫生物群的年代归属分别为:晚三叠世诺利(Norian)晚期至瑞替(Rhaetian)早期,辛涅缪尔(Sinemurian)早、中期。This report deals with systematics of uppermost Triassic and Lower Jurassic radiola boundary sequence in thc Nadanhada Terrane, NE China. Five faunas were illustrated, 1 new cies were described, 121 fossil taxa were documented and figured in this report. By comparing rian faunas from a T-J genus and 10 new spewith well-dated radiolarian faunas from the Queen Charlotte Islands in British Columbia, Canada, and the Mino Terrane in central Japan, the ages of these faunas were assigned to latest Norian, early Rhaetian, early Sinemurian and middle Sinemurian, repectively.
