Aragonite dissolution, sedimentation rates and carbon isotopes in deep-water hemipelagites (Livinallongo Formation, Middle Triassic, northern Italy) - Reply

In a discussion of our recent paper, Maurer and Brack [Maurer, F., Brack, P., 2007. Aragonite dissolution, sedimentation rates and carbon isotopes in deep-water hemipelagites (Livinallongo Formation, Middle Triassic, northern Italy) — Comment. Sedimentary Geology doi:10.1016/j.sedgeo.2006.09.003] suggested that, in the Buchenstein Basin (i.e., the sedimentary basin represented by the Buchenstein Group), sedimentation rates of laminated and bioturbated facies were approximately the same, and post depositional pressure dissolution was the dominant mechanism of carbonate dissolution. The authors drew their conclusions partly from hitherto unpublished data, and partly from the literature. More specifically, their discussion focuses on four points, (i) the reliability of correlations, (ii) the rate of sedimentation of different facies of the Livinallongo Fm. — Buchenstein beds, (iii) the origin of sediments, and (iv) the mechanism of carbonate dissolution. We welcome the new data presented by Maurer and Brack. We believe, however, that some of their points arose from misinterpretations of our study, partly due to a graphical error. In this reply, we take the opportunity to clarify the issues raised by Maurer and Brack [Maurer, F., Brack, P., 2007.
