Surficial deposits of continental areas, economic interest, except for nickel—laterite formed over ultramafic masses. Because nickel—laterite is associated with uplifted oceanic lithosphere in island arcs and continental margins, it is discussed in Chapter 2.

Effekte bei Mehrelektronenatomen,magma, for large-scale circulation of meteoric hydrothermal waters, driven by the magmatic heat source, would have scavenged metals from the country rocks. The mineralization is usually connected with highly differentiated silicic and alkalic fine-grained porphyritic epizonal intrusives belonging to polyphase igneous complexes.

A Spectrum of Sea-floor Sulphides,ated rock assemblage allows their tectonic setting of formation to be deduced fairly accurately. It is generally accepted that they formed at or close to the ocean floor by volcanic-exhalative processes. Summaries of the deposits are given by Hutchinson (1973, 1980) and Sawkins (1976). Their site of

Mineralization in intracratonic basins,ndwanaland. Sea-floor spreading along the major rift system led to the progressive westwards drift of the Americas. The Benue Trough of Nigeria—Cameroons, however, failed to achieve complete separation and ended up as a failed arm or aulacogen (.). Intracratonic spreading axes are closely similar to

Other epicontinental sea deposits,ajor cratonic continents. The sandstone uranium deposits could be included here, but they have such a strong affinity for intracontinental basins that they have accordingly been included in the previous chapter. ‘Epicontinental’ is used here in the sense of including both basins that lie within, as
