The trace element composition of two samples of fluorellestadite from pyrometamorphic rocks (slags) of burnt waste heaps (BWH) from France (LdS) and Poland (RDT) were studied using Laser Ablation Inductively Coupled Plasma Mass Spectrometry. Boron shows an evident, persistent enrichment in both samples, with average/maximum levels of 497/1040 and 49/106 ppm, respectively, as do magnesium (884/16766 and 404/6251 ppm, respectively) and sodium (512/697 and 249/370 ppm, respectively). Germanium is clearly enriched in the first sample (29/40 ppm) and, to a lesser degree, in the second one (34 ppm on average). The LdS sample is also clearly enriched in Al (888/1238 ppm), K (385/697 ppm), Ti (515/943 ppm), V (172/347 ppm), and Cu (16/1369 ppm). The RDT sample is also rich in As (105/120 ppm) and Sr (1072/6592 ppm). In the REE pattern of both samples, Nd dominates, with respective Nd/ΣLREE and Nd/(Ce+La) values of 0.43 and 0.90, and 0.37 and 0.66. From highest to lower average concentrations, aluminium, magnesium, titanium, boron, potassium and germanium may be essential substituents in the BWH apatites.
