摘要
近年来河源盆地的恐龙及蛋化石研究有突破性进展,在东源发现窃蛋龙类oviraptosaurs黄氏河源龙(Heyuannia huangiLu)等恐龙化石,并收集到至少4属4种蛋化石一万余枚;含蛋层可以划分为上、下二层,下层以圆形蛋类及树枝蛋类大量富集为特征,上层以长形蛋为主。在盆地北部新发现了火山岩———弱熔结火山角砾岩,并新建立了适合本区的岩石地层单位系统———仙塘组、东源组、高埔岗组和莘庄村组,它们可与南雄、丹霞等盆地进行对比。
Recently an important advance has been made in the study of dinosaurs and fossil eggs of the Heyuan Basin. Oviraptorid dinosaur （ Heyuannia huangi Lu ）was found in Doyuan County, and more than 10000 of fossil eggs （ belong to 4 genera and 4 species at least ） were collected. The ogg-bearing strata may be divided into two beds, the lower characterized by Spheroolithus-type and Dendroolithus-type eggs and the upper is dominated by Elongatoolithus-type eggs. Weld volcanic breccia was newly found in the north part of the basin. The lithostratigraphic sequence （ the Xiantang, Dongyuan, Gaopugang and Xinzhuangcun formations ） of the Heyuan Basin is established and may be correlated between the basin and Nanxiong, Danxia, and other basins of Guangdong.
