We welcome the opportunity to reply to comments by Axel Liebscher regarding our manuscript (Spandler et al. 2003, Contrib Mineral Petrol 146:205–222). Before discussing the comments, we first wish to state that the phase identified as zoisite in the manuscript should have been labelled as epidote, due to the high ferric iron content. We wish to thank Axel Liebscher and Gerhard Franz for bringing this error to our attention. However, it should be noted that this error does not affect any of the conclusions of the paper, pertaining only to the correct application of epidote-group-mineral nomenclature.
The main focus of our paper is the distribution of trace elements among minerals during prograde subduction-zone metamorphism. We show that the breakdown of trace element-rich phases such as lawsonite and titanite does not lead to a significant change in the trace element content of rocks because the trace elements are redistributed into newly formed major and accessory phases. However, at...
