“…Only few papers have described the geodiversity in the ADB until now, including four papers that discuss geodiversity in the Amazon, namely on the 'Amazônia legal' in Brazil [37] (the northern states of Brazil, including Mato Grosso and the west of Maranhão), the Xingu river basin [38], French Guiana [35] and the NAPO Sumaco (aspiring UNESCO) Geopark [53] (figure 1). De Andrade et al [37] conducted an extensive literature study of geodiversity in the 'Amazônia legal' and concluded that there is still little known about geodiversity in this region, neither is there information on a detailed scale.…”

“…The geodiversity assessment of the Napo Sumaco park ( figure 1 , table 2 ) was performed according to the method proposed by Brilha [ 19 ] and was based on a literature review of the area, as well as interviews with experts of that area to define any geofeatures of interest [ 53 ]. This method does not quantify geodiversity using a grid-based approach but identifies geosites that can be regarded as in situ occurrences of geofeatures with high scientific value [ 19 ].…”

“…This method does not quantify geodiversity using a grid-based approach but identifies geosites that can be regarded as in situ occurrences of geofeatures with high scientific value [ 19 ]. The majority of the geosites were deemed valuable as a result of geochemical properties of the site, or the occurrence of geological geofeatures [ 53 ], and as such highlight the importance of geology in the Napo Sumaco park.

“…Especially the mapping of mineral deposits might give additional information, as articles have repeatedly reported that the (hydro)geochemistry of rivers and soils is affected by the presence of ore deposits. Moreover, it is important to note that although mining activities can increase the degradation risk of geosites [ 53 ], they also create artificial stratotypes and new surface topographies [ 170 ] that locally might increase geodiversity. It would be interesting to research this relationship further, especially in mineral rich sites as the Carajás Mineral Province, which is also home to many special geological features as reported in §4a.…”

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 identify the key characteristics of geodiversity in the Amazon drainage basin (ADB). We also evaluate how these global geodiversity component maps, that are based on the geology, geomorphology, soils and hydrology, could be refined to better reflect geodiversity in the basin. Our review shows that geology—through lithological diversity and geological structures—and hydrology—through hydrological processes that influence geomorphology and soil diversity—are the main determinants of geodiversity. Based on these features, the ADB can be subdivided into three principal regions: (i) the Andean orogenic belt and western Amazon, (ii) the cratons and eastern Amazon, and (iii) the Solimões-Amazon river system. Additional methods to map geomorphological and hydrological diversity have been identified. Future research should focus on investigating the relationship between the geodiversity components and assess their relationship with biodiversity. Such knowledge can enhance conservation plans for the ADB. This article is part of the Theo Murphy meeting issue ‘Geodiversity for science and society’.

Scientific Utility of Selected Latin American Global Geoparks: A Literature-Based Case Study

Global geoparks, i.e., the members of the UNESCO Global Geopark (UGGp) network, possess highly valuable geoheritage resources, which can be used for the purposes of not only education and tourism, but also science. Five examples from four Latin American countries (Chile, Ecuador, Mexico, and Peru) were employed to realize the importance of these global geoparks as facilitators of international research. Journal articles devoted to these geoparks were selected with the major bibliographical databases, and the information from them was analyzed quantitatively. Particularly, the numbers of articles published before and after the UGGp membership, paying significant and marginal attention to geoparks, and published by international teams were calculated; the general themes of the articles were outlined. It was established that the total number of publications grew after the UGGp membership of these geoparks, but not steadily. The established dynamics of publishing are unstable and differ between the geoparks. Geoparks of Mexico (Mixteca Alta) and Peru (Colca y Volcanes de Andagua) are notable examples because they started to facilitate international research before the UGGp membership. Many articles consider geoparks only marginally (nonetheless, there are also articles paying significant attention to geoparks, especially in the cases of two Mexican geoparks). The author teams are often not restricted to Latin America. The research themes are rather diverse (geoheritage, geology, ecology, innovations, society, technology), although the majority of the publications are geoheritage-focused. Of special interest is the Colca y Volcanes de Andagua global geopark, which has been considered in the innovation-focused article. Generally, our results indicate a moderate importance of the considered global geoparks to international research activity and the incomplete exploitation of their scientific potential. Two Mexican geoparks (Comarca Minera and Mixteca Alta) seem to be the most successful in the facilitation of international research. Indeed, the scientific utility of global geoparks should be strengthened.
