A pisolite (from Ancient Greek πίσον (píson) ' pea ') is a sedimentary rock made of pisoids, which are concretionary grains – typically of calcium carbonate which resemble ooids, but are more than 2 mm in diameter. [1]

A pisolite is a sedimentary rock made of pisoid s (= pisolith s), which are approximately spherical, concretionary grains, typically of calcium carbonate, but may be of iron oxides, clays, apatite, etc. They resemble ooid s, but are between 2-10 mm in diameter, while ooids are <2 mm.

Pisolites are distinctive geological structures that have captivated scientists and geology enthusiasts alike. This article delves into the realm of pisolites, providing comprehensive information on their formation, locations, and important details.

The meaning of PISOLITE is a limestone composed of pisiform concretions.

pisolite, spheroidal crystalline particle larger than 2 millimetres in diameter (see oölite). This article was most recently revised and updated by Amy Tikkanen.

Jul 15, 2016 · Terrestrial pisoliths have a wide range of compositions consisting principally of oxides and/or sesquioxides of iron, aluminium and manganese with variable admixtures of kaolinite, titanium oxide, quartz and other weathering-resistant minerals.

Pisolites form by the precipitation of calcium Carbonate around nuclei trapped in sediment within the vadose zone of soils or marine tidal flats (Figure 24). Oncoids form on the surface of intertidal and supratidal flats where Carbonate precipitates from salt water spray and marine flood waters.

Sep 15, 2007 · According to chemical and mineralogical studies of pisolites from E, Bt and Bt/Cg horizons, pisolites in the three horizons consist of well crystallized goethite and hematite, and the pisolite content and hardness decrease with increasing soil depth.

Type of sedimentary rock that is pisolitic in habit, composed of spheroids of layered material larger than 2 mm. In the case of pisolite/pisolitic limestone, the particles are made of radiating Calcite / Aragonite needles. Such sedimentary rocks are also referred to as a pisoliths. Bauxite is another type of Pisolite.

Jun 27, 2017 · A pisolite is a sedimentary rock made of pisoids, which are concretionary grains – often of calcium carbonate, but sometimes of rarer minerals – which resemble ooids but are always more than 2 mm in diameter. These grains are approximately spherical and have concentric layers reaching 10 mm in diameter.
