520 |a"The low-temperature (ca 120-60°C) thermal history of nine samples from four mines was investigated using the apatite fission-track (AFT) method. Analyses correspond to four samples from the Musselwhite mine over a 275 m vertical interval, three from the Roberto mine over a 382 m vertical interval and one sample from both the Meadowbank and Raglan mines. AFT inverse modelling using both HeFTy and QTQt softwares yield concordant results and indicate that a Phanerozoic heating episode was minor (< 20°C) or non-existent over the Musselwhite mine. This contrasts with previous AFT studies that document significant heating (> 20°C) due to sedimentary burial and indicates that the Canadian Shield did not react as a single entity during the last billion years. The thermal history of samples from the Roberto and Meadowbank mines are less constrained due to the lack of ‘high’ (> 120°C) temperature constraints. The sample from the Raglan mine yields the youngest central age among the samples reported in this study"--Abstract.
