Inventory and quantitative assessment of the geological heritage of Paraná State, Southern Brazil

Abstract

The inventory of the geological heritage, along with the quantification of its value, is an essential task for the implementation of geoconservation strategies. Despite the Brazilian’s rich geological heritage, only the state of São Paulo has concluded its systematic inventory. This paper presents the geological heritage inventory of Paraná State and a quantitative assessment of the scientific value of geosites and their vulnerability. The method applied for the geosites evaluation was adjusted after analyzing the most deemed protocols in international literature, taking into account the Brazilian socioeconomic and cultural conditions. The selection of geosites made by experts was based on the following criteria: representativeness, rarity, integrity, and degree of scientific knowledge. The inventory consists of 76 geosites, distributed in nine geological frameworks, which represent the geological evolution of Paraná. It is expected that this work may support future planning and management actions, which can safeguard the state’s geological heritage, with efficient strategies, especially for those places with high risk of degradation.
