Quantitative assessment of the geomorphological heritage of the Pedra da Boca State Park's surroundings: Key geoheritage site in Northeast Brazil

Abstract

The present paper aims to present a quantitative evaluation of the sites of geomorphological interest in the surroundings of Pedra da Boca State Park, Northeast Brazil. The methodology used was based on the proposal and procedures of Diniz, Araújo, and das Chagas’ study in 2022, which considers scientific and aesthetic value as central to the definition of a geomorphosite. After the choice of the form and its due adaptations, the field stage was carried out, consisting of the application of the evaluation at the sites of interest. Thus, to classify a site as a geomorphosite, it is necessary to have a high scientific and/or aesthetic value in quantification. If it does not have a high value in these categories, but has some other potential, it can be considered a geomorphological site. As a result, the geomorphological sites that stood out the most were Pedra da Boca (Mouth Stone) State Park, Pedra da Macambira (Macambira Stone), Cânion do Macapá (Macapá Canyon), Porão do Macapá (Macapá Basement), Pedra do Chapéu (Hat Stone), Cânion da Serra Verde (Serra Verde Canyon) and Peladas (Bare Rock), with only the latter not reaching the quantification needed to be considered a geomorphosite, thus constituting six geomorphosites and one geodiversity site.
