Limonite-cemented fragments of iron formation--called apanhoancango or canga in Brazil (Boyle, 1979). At the Boddington deposit, hematitic nodules, clay with Liesegang rings, and ferruginous and bauxitic laterites occur that are locally indurated ( and others, 1988).

The saprolite and limonite zones tend to contain the higher grades of Ni and can range from 1.5-3% and 1.2-1.7% respectively. How do they form? Many factors affect the formation of nickel laterites, including the original rock the soil develops from, the climate, the rate in which weathering occurs, drainage of groundwater and the tectonic setting.

Iron-oxide nodules or concretions are the most common kind of meteorwrong sent to us. Hematite and magnetite are two common iron-oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because they are heavy (dense) and their unusual (frequently bizarre!) shapes catch ...

The reaction is fast, as much as 20% of iron oxides (hematite, geothite, or limonite but not magnetite or ilmenite) being removed from a soil in 15 minutes, and does not precipitate either elemental sulfur or iron sulfides. Like other procedures, it causes some decrease of exchange capacity of layer silicates which contain iron, and at the same ...

The bulk density of a soil can be calculated on the basis of dry weight of that soil divided by its volume. Thus, Bulk density = Wt. of soil mass/Soil volume. = 87.6 g/76.0 c.c.

Laterite - Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate ...

Limonite is a residual soil produced by the decomposition of magnesium silicate (olivine) rocks in tropical environments. During weathering most of the original rock is leached away leaving only its iron content, which is precipitated out in the form of iron sesqui-oxides to create a soft and highly porous soil.

laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid. Lateritic soils may contain clay minerals; but they tend to be silica-poor, for silica is leached out by waters passing through the soil.
