Apatite Control of Phosphorus Release to Runoff from

2009-1-11  Phosphorus (P) in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P (DP) concentrations (about 0.4–3.0 mg L−1) in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms. Objectives were to

Apatite Trace Element Compositions: A Robust New Tool

Apatite is a widespread accessory phosphate mineral that occurs in many rocks and is relatively resistant to weathering (Bouzari et al., 2011). In general, felsic rocks such as granites, granodiorites, and rhyolites contain ~0.01 to 0.5 wt % P 2 O 5, mainly within apatite (Sha and Chappell, 1999; Belousova et al., 2001; Cao et al., 2012).

Introduction. Apatite [Ca 5 (PO 4, CO 3) 3 (OH, F, Cl)] is the most abundant crystalline phosphate mineral which is found as an accessory mineral in most rock types on the earth surface. However, exploitable deposits of apatite are mainly found in sedimentary and igneous rocks. The former comprises stratiform phosphorite deposits in shelf-type shale-carbonate sequences that contain high ...
