So it was that interest in the Antrim bauxites was rekindled and this led to re-investigation of local reserves. In new bauxite mines were opened at Newtowncrommelin known as the Skerry Mines. Other abandoned workings were reopened for their bauxite content and many Glenravel miners and sons of miners were recruited to work in the new mines. The composition of the laterite is determined by the composition of the parent rock. The most widespread acidic rocks with their high Al- and Si- and their low Fe-content give rise, in favourable cases, to formation of high grade-bauxites. Ferruginous bauxites .

Memoirs of the Geological Survey of Northern Ireland: Mineral Resources. Just one memoir in this series was produced: 'The composition and origin of the Antrim laterites and bauxites' published in The term laterite means a red rock or red earth deposit.
Laterites are formed by the decomposition of different kind of rocks, under conditions yielding aluminum and iron hydroxides.
The different theories of origin are discussed, as well as the chemical process of laterization, and the geographic distribution of this peculiar type of by: 6. All laterites are marked by an enrichment of iron and a decrease of silica together with the highly soluble alkalis and alkaline earths.
But apart of these characteristics the composition and properties of laterites can be quite different and are strongly controlled by the chemical and physical features of the parent rock. Thermal and alternating field demagnetization studies of 23 basaltic lavas of the Lower Tertiary igneous province of Northern Ireland (the Antrim Basalts) have revealed a very stable but composite magnetization: the resultant appears to consist of a dominating reversed component, thought to be the original one, plus a certain superimposed magnetization of normal by: In book: Laterites of the Bengal Basin, pp the primary and secondary origin of laterites in West Bengal.
the mineralogical composition of ferricretes and bauxites are considered to. The lake iron-ores of Sweden, the bog iron-ores of various parts of Northern Europe, the manganese deposits of the Caucasus, and perhaps the iron-ores and bauxites of Antrim, must then all be classed as lake laterites of various by: Many lateritic bauxites are pisolitic (Figure 1).
The word pisolitic comes from the Greek meaning pea-sized rock particles. When cut or broken open their inside surfaces reveal concentric bands of different mineral compositions.

Laterites are a source of aluminium ore; the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. In Northern Ireland they once provided a major source of iron and aluminium ores.
Laterite ores also were the early major source of nickel. The composition and origin of the Antrim laterites and bauxites. With Mineral determinations by X-ray methods.

Mem Geol Surv.Bauxite protoliths are more diverse, since bauxites do not require such tight restriction to protolith chemistry, as is the case for Ni laterites. A few bauxites in the Tethys realm are intercalated within sedimentary rocks of Triassic (e.g., in Iran, Balkan peninsula) and Jurassic ages (e.g., in parts of Greece, Slovenia, Swiss and French Alps.
