The stratigraphic scope of the data is 1) the Polarisbreen Group of NE Svalbard (late Tonian to Ediacaran) and 2) top Appin and lower Argyll Groups, western Scotland (late Tonian to Cryogenian). Geochemical data on carbonates includes, in different cases, stable oxygen and carbon isotopes, strontium isotopes and trace elements. Results from Scotland are published in: Fairchild, I.J., Spencer, A.M., Ali, D.O., Anderson, R.P., Anderton, R., Boomer, I., Dove, D., Evans, J.D., Hambrey, M.J., Howe, J., Sawaki, Y., Wang, Z., Shields, G., Skelton, A.
