摘　　要：在枞阳县某地测制三叠纪黄马青组地层剖面过程中,发现一层含铀砂岩,层厚8.5m,含铀矿物为铜铀云母,呈片状分布于岩层表面、裂隙面和砂岩颗粒之间,拣块取样铀含量超过工业品位。含铀砂岩的发现为在庐枞地区寻找中生代砂岩型铀矿提供了线索。During surveying along a profile across the Triassic Huangmaqing Formation in somewhere,Zongyang County,a layer of uranium-bearing sandstone was found,8.5m in thickness.The uranium-bearing mineral is torbernite,occurring sheetlike on rock layer surface,fissure face and between sandstone grains.Assaying of picked sample gave U content of over industrial grade.This discovery provides a clue to explore Mesozoic sandstone uranium ore deposit in the Lu-Zong area.
