摘要 | Using a museum specimen of perthitic feldspar, the characteristics of post-IR IRSL production at 200 degrees C after different prior IR bleaching at 100 degrees C were investigated. It was found that the post-IR IRSL signal had an isothermal TL contribution that was unexpected following a previous preheat at 320 degrees C; this is the result of isothermal decay of recuperated II peaks resulting from photo-transfer that occurred when the previous IRSL signal was measured at a lower temperature. The isothermal TL contribution to the post-IR IRSL signal depends on prior IR bleaching conditions. Since the recuperated TL signal comes from photo-transfer during IRSL production, this signal should also suffer from anomalous fading. Thus, it is suggested that this isothermal TL contribution to the measured post-IR IRSL is removed by the inclusion of an additional step, a cut-heat to 300 degrees C, in the post-IR IRSL dating protocol. |
