The phosphate mineralogy of et-Tabun cave, Mount Carmel, Israel

Abstract: SUMMARY. Phosphates introduced into the et-Tabun cave as a result of human habitation, mainly as bone material, were partly dissolved by slightly acid solutions (organic acids derived from human or other animal activity). From these solutions, dahllite precipitated when the solutions came into contact with calcite. In the more weathered parts of the section, where little or no calcite occurs, the phosphate minerals formed are montgomeryite and crandallite.

“…These observations all support the notion that in both these caves ash calcite dissolves and the calcium ions react with phosphate and carbonate molecules to form dahllite. A similar phenomenon has been observed in the reaction rims of both calcitic and dolomitic rocks buried in the cave sediments (Goldberg & Nathan, 1975;Weiner et al, 1993Weiner et al, , 1995a. The two most likely sources of phosphate are guano and the bones buried in the sediments.…”

“…Although the diagenesis of cave sediments and cave mineralogy have been emphasized in speleological research for several decades, it took the systematic study of the sediments at Kebara and Hayonim Caves in Israel during the 1990s to document these processes and their ramifications. 8,15,18,19,[63][64][65][66][67]85,87,126,127 More recently, however, similar types of studies have been carried out in Greece and other parts of Europe. 17,22,61 One unique aspect of these studies is the immediate results derived from performing these analyses in the field.…”

“…It is equally important to determine how much the evolution of the external dose in strata overlaying Layer D in the intermediate cave might have been affected by the detected disturbances apparently provoked by running water, as any prolonged flow could have leached some U and its water soluble descendants. As a matter of fact, it appears that not all the geological deposits in question were affected to the same degree (Goldberg and Nathan, 1975). Thus, in contrast with Layers D-G where no bones had survived, B and C could not have been strongly disturbed as they contained many well preserved microfaunal and charred organic remains.…”
