laterite and occur as blankets or as capping on the high plateaus in peninsular India. India has the fifth largest bauxite reserves which are 7% of world deposits. India's share in world aluminum capacity rests at about 3%. India has large resources of highgrade bauxite deposits of the order of 3037 million tons (proved + probable + possible).
to have some aluminous laterite developed. Particular attention was therefore devoted to plateau areas of limestone with a mantle of red soil because of the similarity to the mode of occurrence of the bauxite in Jamaica. The limestone plateau area north of Guantanamo seemed especially favorable because it may
Lateritic soil has less than 30% silt content, between 2563 % liquid limit and 542 % plasticity index [1114]. On this ground, it is understandable that the geotechnical properties of lateritic soil could be improved before there usage for engineering purposes. Otherwise they are bound to cause damages
Big Bang Theory: Origin of the universe bil years ago. Cosmos goes through superfast "inflation" expanding from the size of an atom to a grapefruit in a fraction of a second. Post inflation universe is hot "soup" of electrons, quarks and other particles. a a rapidly cooling cosmos permits quarks to clump into protons and neutrons.
· The Laterite sample composed Goethite and Gibbsite. Gibbsite is colorless to pale brown. The Gibbsite is noticed where the lateritization is taken place, the lateritization is observed in the left portion of the sample. The rock sample is aluminous Laterite. Fig. 4.

The laterite deposits occur in a linear stretch along the northern Arabian Sea coast in the Jamnagar and Porbandar districts of, Gujarat state, India. These deposits are characterised by presence of gibbsite, kaoline, calcite, quartz, anatase, natroalunite, goethite and hematite, and relicts of mafic minerals and plagioclase. On the basis of petromineralogy and geochemistry, .
They have a higher content of silica (~ 20 %), reason why they are not exploited yet. In southeastern Brazil, the cover is rather thin and it is characterized by the presence of kaolinite and aluminous vermiculite. These lateritic deposits as a whole cover nearly 75 % of the Brazilian surface and have very few indurated layers.
In the Paduvari Plateau of coastal Karnataka, the occurrences of aluminous laterite or bauxite (– m thick) underlain by ferruginous laterite (– thick) signify that climate was evolved from humid tropical to tropical wet–dry condition in the Paleogene–Neogene Periods (Tardy, 1992, Devaraju and Khanadali, 1993). The deep .

Malabar Region of coastal Kerala and Dakshin Kannada other parts of Karnataka It is a highly weathered material rich in secondary oxides of iron aluminium or both It is either hard or capable of hardening on exposure to moisture and drying Laterite and bauxite show a tendency to occur together Aluminous laterites and ferruginous
A lateritic profile overlies the ultramafic rocks (see Figure 2). The distribution of ultramafic rocks (a large southeastern massif and smaller ones along the northwestern coast, with various elevations and a stepped lateritic surface) is the result of the combined effects of isostatic postorogenic uplift, tectonics, and erosion.
The word Laterite is derived from Latin word 'later' which means 'brick'. They are mainly tropical based reason's soil where we have heavy seasonal rainfall and high temperature. Because of that, it promotes leaching of the soil. Due to rain, lime and silica are always leached away. Laterite soils are said to farraginous aluminous rock.
Formations of Cenozoic age occupy the eastern coastal plains in form of alluvial sediments, ash beds and low level laterite, providing avenues for occurrence of beach sand minerals and building materials. The deltaic fans extending into offshore regions play hosts for oil and gas. Odisha has a lion's share of the Country's mineral reserves.

Alternate name for the plagioclase series of feldspars. In petrology, the plagioclase series are defined based on their percentage of albite (Ab) to anorthite (An). Compositions of individual samples are usually written as An24Ab76 meaning in this case that it is 24% anorthite and 76% albite. List of plagioclase group members as used in petrology.
· 1. COAL A principal mineral fuel, coal is a combustible, solid stratified rock of organic and mineral matter. The organic matter constitutes carbon (60 to 90 per cent), hydrogen (one to 12 per cent), oxygen (two to 20 per cent), nitrogen (one to three per cent) and also small amounts of phosphorus and sulphur.
The laterite deposits occur in a linear stretch along the northern Arabian Sea coast in the Jamnagar and Porbandar districts of, Gujarat state, India. These deposits are characterised by presence of gibbsite, kaoline, calcite, quartz, anatase, natroalunite, goethite and hematite, and relicts of mafic minerals and plagioclase.
Laterite is the product of intense weathering in humid, warm, intertropical regions and is typically rich in kaolinitic clay as well as Fe and Aloxides/oxyhydroxides. Laterite may be subdivided in two types, one is ferrugineous, which is called Ferricrete and another is aluminous, which is called alcrete or, bauxite.
Petrological analyses, recently realised on lateritic profiles in Congo (Muller et al., 1981), Ivory Coast (Nahon et al., 1977, Boulange, 1983) and Cameroon (Sarazin 1982, Rose110 et al., 1982) have described some mechanisms which occur during lateritisation.
· The laterite deposits of Swarnagadde plateau occurs in Uttar Kannada district of Karnataka state, forming low altitude flat topped laterite hills and plateaus adjoining part of Central Western Ghats, in the western continental margin of India.
