Calibración del separador magnético de alta intensidad magnet-lift mlh (13) 111-5 para su uso en el laboratorio de termocronología de la UCVCalibration of a high intensity magnet-lift mlh (13) 111-5 magnetic separator for use in the thermochronology laboratory of the UCV. Rev. Fac. Ing. UCV [online]. 2007, vol.22, n.3, pp.73-84. ISSN 0798-4065.

In this article we present the calibration of a high intensity Magnet-lift MLH (13) 111-5 magnetic separator located in the Thermochronology Laboratory of the Universidad Central de Venezuela with the purpose of magnetically separating minerals of sandstone and granite samples to be subsequently subjected to the fission track dating method (FTDM). The results of this calibration were applied to 10 kilogram sample belonging to an initial concentration of minerals of Betijoque´s Formation on the north flank of Venezuelans Andes. We conclude that the Magnet-lift presents a number of advantages with regard to conventional magnetic separators as well as optimizing the preparation time of detritic rocks for their dating by the fission track method.
