黔东北瓮会生物群是继鄂西庙河生物群、皖南蓝田植物群和黔中瓮安生物群之后在扬子地区伊迪卡拉纪陡山沱期发现的又一宏体生物群。通过对黔东北江口枫香岭、张屯、瓮会、松桃牛郎及铜仁小湾龙等剖面的初步分析研究,在坝盘—瓮会一带可能存在一个规模较小的、走向南西-北东向的古断裂。化石特征及生物所需要的物质来源、营养盐分等也因古断裂的活动而受影响。断裂活动也为生物的生活提供丰富的营养盐分。弱氧环境使得部分生物死亡后残体被氧化分解,但大量的生物有机体被很好地保存,为烃源岩(干酪根)的沉积与埋葬提供有利的条件。
Guizhou Urn Society Biota is another macroscopic biome that was found in the Doushantuo Period of the Idiacaran in the Yangtze area, following the Miaohe Biota in western Hubei, Lantian in South Anhui and the Weng’an biota in Central Guizhou. Through the preliminary analysis and study of the profiles of Maple Ridge, Zhangtun, Urn, Songtao Cowherd and Tongren Xiaowanlong in the northeastern Guizhou Province, there may be a small scale of southwest-north The ancient fracture of the east. Fossil traits and biological sources of material needed, nutrient levels are also affected by ancient fracture activities. Fracture activity also provides abundant nutrients for living creatures. In the environment of weak oxygen, some residues are oxidized and decomposed after the death of some organisms, but a large number of biological organisms are well preserved, which provides favorable conditions for the deposition and burial of source rocks (kerogen).
