"description": "A comprehensive stratigraphic chart detailing the geological formations, members, groups, and their corresponding lithological characteristics in the Kingdom of Saudi Arabia. The chart spans from the Precambrian to the Permian period, illustrating the general chronostratigraphy and associated tectonic movements. It is presented in two main vertical sections, with the right section covering older periods (Precambrian to Permian) and the left section providing more detailed information for some formations, implicitly continuing the sequence.",

"x_axis": "Not applicable (stratigraphic column)",

},
"data_description": "The chart is organized into columns: 'Age' (العمر), 'Group' (مجموعة), 'Formation (Fm)' (متكون), 'Member' (عضو), and 'Generalized Lithology' (الخصائص الصخرية العامة). Vertical labels indicate major geological eras like 'Paleozoic' (الحياة القديمة). Various rock types are represented by standard geological patterns in the lithology column, including limestone/dolomite (horizontal lines), sandstone (dots), shale/mudstone (brick/block patterns), and evaporites (wavy lines). Several tectonic movements are also indicated at specific stratigraphic levels.",
