Reply to discussion of “A refined genetic model for the Laisvall and Vassbo Mississippi Valley-type sandstone-hosted deposits, Sweden: constraints from paragenetic studies, organic geochemistry, and S, C, N, and Sr isotope data” by D. Sangster

Abstract

The very MVT definition includes ore deposits hosted in sandstone. Owing to the fact that the sandstone-hosted Pb-Zn deposits at Laisvall and Vassbo are epigenetic, formed by basinal brines long after deposition of the host rock, and this by the same mechanisms as those recognized in many carbonate-hosted MVT deposits, we maintain that using the term MVT is appropriate, useful, and has implications for the conceptualization of exploration models.
