“…It is thus not surprising that the wide and recent literature on bauxite deposits has focused on the genetic mechanisms promoting the formation of this type of sedimentary rock (e.g., Mongelli, 2002;Laskou and Economou-Eliopoulos, 2007;Mameli et al, 2007;Zarasvandi et al, 2008;Hoefs, 2009;Karadağ et al, 2009;Wang et al, 2010;Boni et al, 2013;Hanilçi, 2013;Zarasvandi et al, 2013;Abedini and Calagari, 2014;Mongelli et al, 2014;Peh and Kovačević Galović, 2014;Yu et al, 2014).…”

“…Bauxite deposits that occur in limestones have been defined as karstic deposits, regardless of their parent rocks (Patternson, 1967;Bárdossy, 1982;Bardossy and Aleva, 1990). On the other hand, bauxite deposits that overlay alumosilicate rocks and were formed by their in situ lateritization are called laterite-type or silicate-type deposits (Bardossy and Aleva, 1990;D'Argenio and Mindszenty, 1995;Öztürk et al, 2002;Liu et al, 2010;Wang et al, 2011;Yu et al, 2014;Mongelli et al, 2016;Zamanian et al, 2016;Liu et al 2016;Torro et al, 2017;Yang et al;. As can be seen from the above classification, while lateritic-type or silica-type bauxite classification depends on the parental rock, the karstic-type is independent of the source rock.…”

The Payas region bauxite deposits occur as a sandwiched layer that is a few kilometers long and an average of 10 m thick between the lower and upper Cretaceous carbonates of the Arabian Platform. The bauxites occur as blanket and pocket types, are chemically and texturally homogeneous and have a thrust structure with ophiolitic mélange formations. The bauxite varies in color, from reddish-brown to grayish-green to black, and has a massive, patchy and very rare oolitic-pisolitic texture. The bauxite mainly consists of diaspore, hematite, rutile, anatase, rare kaolinite, boehmite and pyrite minerals. Prismatic and lath-shaped euhedral rutile within the bauxites indicates in situ formation of the bauxites from Ti-rich basaltic pyroclastics. The chondrite-normalized REE pattern of the bauxite is similar to the basalt pattern and has a very weak Eu anomaly (0.9). Two groups of elements have been enriched in the Payas region bauxite: the first group contains TiO 2 (9.67 wt%), Cr (752 ppm), V (617 ppm) and Ni (72 ppm), and the second group comprises Zr (993 ppm), Nb (86 ppm) and Sn (7 ppm). These two groups of element enrichment indicate that the parental material of bauxite has an alkali basalt character. The carbon and oxygen isotope stratigraphy throughout the carbonate section from the bottom to the top indicates that the climate was warm during bauxitization (mean δ 18 O VPDB :-6.15‰) and relatively cold after bauxite deposition (mean δ 18 O VPDB :-4,71‰). A marine regression during the warm climate could be related to the uplifting of the coastal zone, which is linked to vertical fault movements of normal faults. A rapid transgression after bauxite formation during the cold climate period can be explained by subsidence of the continental margin, which is associated with episodic ophiolitic nappe loading during the closure of the Neotethyan Ocean in the region.

“…Microstructural properties of oxide and silicate minerals of aluminum and iron were studied from the representative samples (sample 1-6) under Scanning Electron Microscope (SEM). SEM studies on bauxite had been reported by Yu et al [13]; Bhukte and Chaddha [14]; Ling et al [15] and Sahoo et al [11]. The work focuses on the microstructural and morphological characteristics of bauxite minerals and their genetic development.…”

In this study, we present the main findings from microstructural and mineralogical studies and their implications for the genesis of bauxite/laterite in Mainpat plateau. Megascopic studies showed reddish laterite to off-white bauxite. Strong hydrolytic action formed small oolites and large pisolites with sizes of 1-2 cm in diameter. Pisolites and oolites were elliptical, circular, and as broken pieces. Matrix of gibbsite and hematite was found in petrographic observations. Morphological characteristics include pisolitic, oolitic, lamellar, and euhedral gibbsite. Microstructures discovered were spongy gibbsite, flower-like crystals, elongated gibbsite, and framework type. Crystals of gibbsite were found to be predominant with partially crystallized ilmenite and hematite as subordinate phases. Scattered bauxite crystals made free pores for passage of solutions enhancing leaching conditions. Al, Ti, Fe, Si, Cu and Zn were identified as significant components; out of which, Al and Ti have the highest concentration. The samples have high alumina constitutes of 61.45% and 65.40% with a low iron content of 6.66% and 5.61%. High Ti content of 19.38% and 17.55% might be due to strong hydrolytic action during the alteration of basalt to bauxite. Low Si content of 2.68% indicates strong leaching activity. XRF analysis showed that the samples have undergone strong lateritization. XRD examination of bauxite/laterite revealed a mixture of minerals like gibbsite, boehmite, goethite, hematite, and anatase. Enrichment in boehmite shows in situ weathering. The study aims to extract the genesis and depositional characterization of bauxite through its morphological, microstructural, and mineralogical properties.
