Dreikanter-like pebbles of haematite ore, Carajás, south-eastern Amazonia, Brazil

Autor: C. H. C. Costa, J. C. S. Seoane, A. R. Cabral

Publikováno v: Applied Earth Science. 115:9-12

A pavement of faceted pebbles of haematite ore has been discovered in Amazonia. It occurs on the top of a lateritic plateau in Carajas, beside lakes and marshes where the available palynological data indicate dry periods during the Pleniglacial. The
