Аннотация: Phosphorites are sufficiently widespread in caves (Hutchinson, 1950; Maksimovich, 1963, 1966). Their formation is mainly attributed to the interaction of decomposition products of bat guano with cavity wall rocks. The guano is also sometimes considered cavity phosphorites (Maksimovich, 1966). This is, of course, incorrect. There arПоказать полностьюe a few descriptions of cavity formations composed of inorganic phosphates that can be considered real phosphorites. The most scrutinized descriptions of phosphorites are related to caves in Java Island (Narchemashvili and Sokolov, 1963) and iron ore deposit areas in the Bomi Hill and Bamuta regions in western Liberia (Axelrod et al., 1952). The Java Island phosphorites include F-free (carbonate)apatite and alumophosphates that are composed of crandallite, as suggested by the chemical composition presented in (Narchemashvili and Sokolov, 1963). The major phosphate minerals in cavity phosphorites of Liberia are leucophosphite, phosphosiderite, and strengite (Axelrod et al., 1952). The presence of cave phosphorites has also been reported from different regions of the world (Hutchinson, 1950; Maksimovich, 1963). However, their detailed description has not been presented in the literature so far.
