The sediments are compositionally mature to submature and classified as quartz arenite to sub-litharenite.
The transfer of interests in P2304 from Europa and Arenite to Egdon is subject to OGA approval.
The Lard Formation is mainly a calcite-cemented, fine- to medium-grained, well- to sub-rounded to sub-angular, 90 percent quartz arenite of marine shoreface origin (Hickin and others, 2010).

"The carbonate always has a different behavior than arenite, which is more homogenous.

The sediments were affected by minor tectonism which ultimately led to the development of mature sandstones nomenclature as Quartz arenite and Quartzose arenite.
The magaripples occur on the upper bedding plane of a 35-cm thick, medium to coarse-grained quartz arenite. This bed is both underlain and overlain by fine quartz sandstone, interbedded with micaceous siltstone beds, some of which preserve a well-developed Cruziana ichnofacies association.
The marine unit is characterized by a well-sorted, subrounded, low sphericity, fine-grained quartz arenite representing sediments of the Princess Anne terrace.
From a geo-lithological point of view, the area is characterized by a wide heterogeneity of types: from clayey-calcareous substrata such as limestone, calcareous arenite, silty marl, grey clayey marl, polychromatic marl and clay, to siliceous sandstone.
Fine-grained sandstone, quartz arenite. Some is partially metamorphosed; quartz porphyroclasts in a partially recrystallized and aligned matrix and boundaries of some of the quartz porphyroclasts are breaking down.
