Figure 2. Cement stratigraphy in the Lower Devonian La Vid Group showing the different cement generations, the associated fluid and the estimated abundance of the cements in the La Vid Group. The major cement types of S-Dol 1, S-Dol 3 and Cal 3 are described in the text. Other minor cement generations, are not mentioned as they could not be clearly defined due Bar: Barite, BP-Styl.: Bedding-Parallel Stylolites, Cal: Calcite, Cel: Celestite, HC: Hydrocarbons, LPS-Styl: Layer-Parallel-Shortening Stylolites, S-Dol: Saddle Dolomite.
