Ferroan Dolomitization by Seawater Interaction with Mafic Igneous Dikes and Carbonate Host Rock at the Latemar Platform, Dolomites, Italy: Numerical Modeling of Spatial, Temporal, and Temperature Data

Figure 2

Summary of field observations (a) Dike-carbonate contact showing replacement ferroan dolomite bordering a dike. Here (and in general) ferroan dolomite occurs close to the dike, while nonferroan dolomite occurs further away from the dike. Numbers indicated in the figure correspond to XRD spectra shown in (2b). (b) XRD diffractograms based on samples from (2a), including nonferroan (1) and ferroan (2) dolomite. Sample locations are indicated in (2a). Towards the dike, there is a shift from nonferroan dolomite to ferroan dolomite. (c) Schematic interpretation of (2a).
