Field photographs of the Pikermi and Rafina formations.

a-d, Red Conglomeratic Member of the Pikermi Formation along the Megálo Réma rivulet. a, Red aeolian silts and conglomeratic levee of a dominant debris-flow from the upper part of the PV1 section. b, Lenticular shaped, dominant (‘doubled’) debris-flow, middle of PV3 section. c, Same debris-flow as b with undulating surface. d, Same debris-flow as b and c, with projecting cobbles (length of hammer 35 cm). e-g, Transition from the Red Conglomeratic Member to the Chomateri Member of the Pikermi Formation in the northern former clay pit Chomateri. e, Section Chom-A (northern view) with slight dip of sediments to the south-east. The transition between members is indicated by an arrow. f, Same as e, with channel-fill trains at the base of the Chomateri Member. g, view to the east of laterally continuous channel-fill trains. h, Chomateri Member of the Pikermi Formation in the southern former clay pit Chomateri. Section Chom-B showing the prominent 2.2-m-thick calcic palaeosol (E-Btk-Bk soil horizons) at the base (Btk and Bk horizons deeply rooted by macro-rhizolithes), overlain by faint and dominant fluvial channel-fill trains. i, j, Upper part of the Rafina Formation. i, Lacustrine marls and limestones with organic-rich interlayers (arrow). j, Planorbis shells from marl horizons.
