Abstract

[Abstract] Amacroscopic pyrophyllite bearing mineralization related to shells ofspiriferids has beeen found in the Herrera Formation (southern Central-Iberian Zone, Hesperic Massif, Spain). The observed mineral asociation is pyrophyllite + nacrite + quartz + calcite + anhydrite, and it is interpreted as resulting from the substitution ofinitial carbonatic shell by a Si, Al, S rich hydrothermal solutio
