Os solos carbonatados resultantes do desenvolvimento de crostas calcárias (calcretos) em climas sub-húmidos e semiáridos e os solos gipsíferos resultantes do desenvolvimento de crostas gipsíferas (gipcretos) em meios desérticos apresentam propriedades específicas e comportamentos geotécnicos particulares que estão relacionados com o teor de finos carbonatados e gipsíferos. Os ensaios de identificação convencionais encontram sérias restrições e falham quando são aplicados a solos carbonatados e gipsíferos.

Abstract:
Abstract Extensive development of calcrete deposits is observed in the Saswad-Nira area of western Maharashtra. Calcrete occurs in a variety of forms, the most common being powder, nodular, laminar, platy, tubular and hardpan calcretes. The DTA, XRD and IR spectroscopic studies show that the calcretes are composed chiefly of micrite - a microcrystalline calcite. Dolomite and opaline silica occur in subordinate amounts. The clay fraction of calcretes is dominated by attapulgite (palygorskite) and sepiolite, which along with other interlayer clay minerals like chlorite-montmorillonite and illite

Abstract:
Calcretes are indurated terrestrial carbonates that are widespread in arid and semi-arid settings and serve as important archives of present and past environments. Here, we use geochemical tools to explore the nature and origin of calcretes documented from tropical Niue Island in the Southwest Pacific. The study recognizes two types of calcretes that differ in their mineral assemblage, microfabrics, elemental chemistry, and carbon and oxygen isotopes. The calcretes common in the paleo-lagoon soils consist of 90% low-Mg calcite and ~10% highly weathered Mg-Al silicates. These pedogenic calcrete

Abstract:
AbstractThe use of calcrete horizons as a means of assessing rates of sediment accretion in ancient alluvial sequences is reviewed. Any attempt to use such horizons in quantifying ancient alluvial deposition must appreciate that accurate data on rates of formation of Quaternary calcretes are limited. Such data show considerable variations in the rates and no reliable data exist at all for some calcrete types. The abundance of calcretes in the geological record warrants a new initiative to improve our understanding oftheir origins and rates of formation.

AbstractThis paper addresses the mineralogy, geochemistry, and genesis of palygorskite and associated calcretes in the Kırşehir region. In this area, the Quaternary calcretes are present within and/or on lacustrine mudstones of the Kızılırmak Formation (Late Miocene-Pliocene). The calcretes occur in the form of nodules, tubes, fracture-infills, and hard laminated crusts (hardpans). Calcrete samples are predominantly composed of calcite associated with smectite, quartz, feldspar, and minor palygorskite. The lacustrine mudstone samples consist mainly of smectite and palygorskite with minor calci

Abstract:
The arid Yilgarn region of Western Australia contains numerous isolated calcrete aquifers, within which a diverse subterranean fauna has been discovered. Genetic and morphological studies of subterranean dytiscid beetles and amphipods have suggested that individual calcretes are equivalent to closed island habitats, which have been isolated for millions of years. Here we test this ‘subterranean island’ hypothesis further by phylogeographic analyses of subterranean oniscidean isopods (Haloniscus), using mitochondrial DNA (mtDNA) sequence data derived from the cytochrome c oxidase subunit I gene

Abstract. The chronology of the Cenozoic “Namib Group” of the Namib Desert is rather poorly understood and lacks direct radiometric dating. Thus, the paleoclimate and landscape evolution of the central Namib Desert remains imprecise, complicating the detailed search for global and/or local forcing factors for the aridification of the Namib. The widespread occurrence of calcretes and silcretes in the Namib Desert allows us to apply the novel application of the U–Pb laser ablation dating technique on silcretes and calcretes to date important phases of landscape stability and to retrieve critical

Abstract:
The pedogenic carbonates, found mainly in arid and semi arid regions of the world, are commonly referred to as calcretes or caliche or kankar. These are authigenic carbonate products which occur in association with soil, forming the residual regolith. Many rock types can produce calcretes upon weathering and denudation, but calcrete derived from certain rocks like kimberlite lamproite acts as an exploration guide. Calcrete is a prominent sampling medium in diamond rich countries like Australia and South Africa whereas it has not received popularity in the Indian context. Kimberlites being ultr

A striking diversity of species from the bathynellacean family Parabathynellidae have been found in the calcretes of the Yilgarn palaeodrainage system in Western Australia. Taxonomic studies show that most species are restricted in their distribution to a single calcrete, which is consistent with the findings of other phylogeographic studies of stygofauna.

The Yilgarn calcrete aquifers in Western Australia are an interesting system for investigating the process of speciation within subterranean habitats, because of the limited opportunities for dispersal between isolated calcretes. The presence of different-sized diving beetles (Dytiscidae) in separate calcretes, including sympatric sister-species pairs, suggests that species may have evolved within calcretes by an adaptive shift as a result of ecological-niche differentiation. We have studied the potential for trophic niche partitioning in a sister triplet of diving beetles, of distinctly diffe
