Abstract
This paper presents the fission track age and multielemental analysis of the Durango fluorapatite (Cerro de Mercado, Durango, Mexico) performed by laser ablation-inductively coupled plasmamass spectrometry (LA-ICP-MS). A mean age of 31.2 ± 0.2 Ma (1σ) was obtained from 104 fission-track ages determined in 12 different fragments, which is in close agreement with the accepted value of 31.4 ± 0.5 Ma (1σ). The literature about the chemical composition and age of the Durango apatite was also reviewed and the results obtained in this study (REE, trace elements and fission-track ages) are consistent with the published data. This study also presents a new equation for calculating the uncertainty of fission-track ages taking into account all analytical errors. These results validate the procedure used and allow this methodology to be used routinely in other apatites.
