- Abstract:
- Apatites are the most abundant phosphorus-bearing minerals, found extensively in igneous and sedimentary rocks. The presence of fission tracks and 4He, produced from radio-active decay of, for example, uranium make apatites excellent geo- and thermo-chronometers in the mantle. In aqueous environments, apatites are found to ion-exchange the calcium ions for heavy metals. The aim of the research is to use computer simulation techniques to investigate the major factors determining impurity behaviour in apatite crystals: first the behaviour of impurities such as 4He, uranium and rare earth elements in the bulk crystal, secondly grain boundaries and interactions between crystalline and amorphous phases, and finally the formation of pure apatite in aqueous environments followed by surface absorption and subsequent segregation of contaminant ions from solution into the mineral.
