The Tambien Group in Tigrai, Ethiopia, comprises a number of inliers each containing 2–3 km thickness of interbedded carbonate and clastic sediments, capped in one inlier by a glaciogenic diamictite. A range of geochemical indices suggest near-pristine C- and Sr-isotope values are preserved and thes...
