Data for: Thallium isotope ratios in shales from South China and northwestern Canada suggest widespread O2 accumulation in marine bottom waters was an uncommon occurrence during the Ediacaran Period

Thallium isotope data from Ediacaran-aged shales from South China (Doushantuo Member IV) and northwestern Canada (Sheepbed Formation, Nadaleen Formation, Blueflower Formation).

本数据集包含采自中国南方埃迪卡拉纪（Ediacaran）页岩（陡山沱组四段，Doushantuo Member IV）以及加拿大西北部（绵羊床组、纳达林组、蓝花组）的铊同位素数据。
