TL;DR: In this paper, the vertical distribution of a wide range of elements (including REEs and selected trace elements) throughout the Apulian karst bauxite deposit was shown in order to identify the processes determining element frac- tionation during the evolution of Bauxite.

TL;DR: In this article, a comprehensive study of pebbles from the Salento-type allochthnous bauxite deposit (Otranto, southern Italy) was performed for evaluating: 1) the chemical fractionation and inter-elemental relationships, especially for critical elements, and 3) the provenance of the protolith(s) using zircon ages and conservative elemental proxies.

TL;DR: In this paper, the authors focused on the Late Cretaceous Bidgol bauxite deposit in the Zagros Simply Fold Belt, SW Iran and performed detailed mineralogical analysis.

TL;DR: In this article, the authors present results of univariate and multivariate (R-mode factor analysis) statistics performed on a large data set including chemical composition of the principal Cretaceous karst bauxites from central and southern Italy with the twofold aim to evaluate the inter-elemental relationship among major oxides and critical metals, and describe factors affecting their distribution.

TL;DR: The Apulian Carbonate Platform (ACP) in southern Italy has experienced several episodes of subaerial exposure, which were in some cases associated with the formation of karst bauxite deposits as mentioned in this paper.
