Edaga Arbi Glacials (Ethiopia)

The Edaga Arbi Glacials are a Palaeozoic geological formation in Tigray (northern Ethiopia) and in Eritrea. The matrix is composed of grey, black and purple clays (locally silt), that contains rock fragments up to 6 metres across. Pollen dating yields a Late Carboniferous (~323 million years or Ma) to Early Permian (~295 Ma) age.^[1]
