The geoenvironmental analysis constitutes a multidisciplinary tool capable of evaluating in an
integrated way the socio-environmental dynamics based on the geological, geomorphological and
pedological processes, based on this assumption this work had as main objectives to characterize
the geoenvironmental function of the doliniform depressions located in the Araguaia Plain , in the
central region of Brazil, four stages were structured for this purpose, the first stage consisting of a
bibliographical review containing the theoretical foundation of the possible karst characteristics of
these features; in the second stage, the terminologies used in the naming of these doliniform
structures were identified, through linguistic methods such as the application of the toponymic
lexicographic form and network analysis to evaluate the relationship of the use of terminologies in
different academic studies. In the third stage, the mapping and analysis of the morphometry and
distribution of the depressions was carried out through the photointerpretation of images from the
Sentinel 2A satellite superimposed on digital elevation models of 30 meters of resolution; and in
the last stage, the geoenvironmental function of the doliniform depressions in the context of the
landscape was analyzed by superimposing thematic maps and applying a geospatial model of
environmental susceptibility. The results obtained through a toponymic lexicographical form
identified a close semantic relationship between the typologies ipuca, impuca and dolina associated
with flooded depressions covered by vegetation, as their meanings emphasize the idea of water as
a strong shaping element of the terrain. On the other hand, the application of ipuca terminologies
represented a high frequency in works of an interdisciplinary nature, while the concept of ipuca
was widely observed in floristic (disciplinary) studies. Through mapping and morphometric
analysis, it was possible to identify 24,023 doliniform features in an area of occurrence of 114,900
km², of which most of these formations are located in the municipalities of Cocalinho – MT,
Luciara – MT, Ribeirão Cascalheira – MT, Lagoa da Confusion – TO and Pium – TO, having its
origin possibly associated with the dissolution of a limestone layer underlying the sedimentary
layer of the banana plantation, due to its predominantly circular shapes and predominant alignments
in the NE direction, indicating a possible structural control over these features. The analysis of the
geoenvironmental function obtained by the susceptibility model showed that ecotonal regions with
high density of features are located in highly susceptible areas due to the increase in denudation
processes resulting from deforestation and high water intake in the region.
