Geodiversity in the Amazon drainage basin. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci
The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic landscape features. In spite of this, the geodiversity in this basin has not yet been objectively evaluated. We address this knowledge gap by combining a meta-analysis of an existing global geodiversity map and its components with a systematic literature review, to
