лимонит

Тезаурус:

1. Some are finely crystalline (clay minerals, hematite, limonite), others are coarsely crystalline (similar to carbonate burial cements) and commonly poikilotopic, whereas yet others are both coarsely crystalline and, to some extent, appear to replace the host sediment (anhydrite, halite, phosphates, glauconite) (Fig. 5.33a).
2. Chemical weathering is rare in cold desert soils, though limonite, clay minerals and other typical products have been reported, and the breakdown of ferromagnesian minerals to reddish iron oxides is apparent on many rock pavement surfaces (Tedrow and Ugolini, 1966; Allen and Northover, 1967; Ugolini, 1970).
3. A small gossan of cavernous quartz with limonite and traces of gold was found at Bardon Hill in 1950 (King, 1967).
4. Here the ground was uneven limonite and she stumbled.
