Stratigraphically, the studied rock succession could be differentiated into four distinct informal rock units represented by ledge-forming argillaceous limestone (LFAL), ledge-forming sandy limestone (LFSL), slope-forming calcareous claystone (SFCC) and slope-forming bituminous shale (SBSh) (Fig. 2). In the area of study, the rocks of LFAL …
