Porosity Development Controlled by Deep-Burial Diagenetic Process in Lacustrine Sandstones Deposited in a Back-Arc Basin (Makó Trough, Pannonian Basin, Hungary)

Figure 1

Maps of the studied area. (a) Depth of the Neogene basement of the Pannonian Basin [40]. The thick line indicates the largest known extension of Lake Pannon 9.5 Ma ago, whereas the dashed lines mark the position of the shelf-edge at between 6.8 Ma and 5 Ma [30]. White and black arrows indicate major rivers entering the basin and main direction of the sediment transport, respectively [25]. Rectangle shows the location of map on (b). (b) Map of Neogene basement depths and highs with the location of the Makó Trough; the studied wells are marked by yellow [41]. Location of the seismic line (Figure 4) is indicated by a dashed line. Oil and gas fields are indicated with green and red colors, respectively. Inset map shows Europe and the location of map (a) (rectangle). Hydrocarbon fields are indicated with grey color.
