Close-up of beige and grey sedimentary rock with a coarse, fossiliferous texture. Several deep, circular holes of varying sizes are eroded into the surface. — Once Upon a Time Beneath the Water Antonio Jordán

Large fractured limestone blocks at Cerro del Hierro, Seville, surrounded by reddish soil and sparse vegetation. The central rock shows several cracks and weathered surfaces. — The Unseen Work of Weathering Antonio Jordán

Close-up of a cut brachiopod shell in rock: wavy dark grey and silvery layers rimmed with rusty orange, above a band of glassy brown grains and a striped shell fragment. — Altered Tremadocian brachiopod, Ülgase, Estonia Sophie Graul

High rock cutting: an upper cliff of rugged orange-yellow dolomite above a pale grey layer, a thin whitish band and lower pale rock, beside a sandy track under a hazy sky. — Dolomite–Shale–Gypsum Succession Exposed in Uptown Cairo, Egypt Ahmed-M- Mohy

Close-up of a white limestone block scattered with small rounded tan and orange fossil grains, with a laptop screen blurred in the background. — Microscopic Fossils Preserved within Limestone from El-Ghanayem, Assiut, Egypt Ahmed-M- Mohy

Large rounded hill of pale orange layered rock rising from a desert slope, with many people climbing it and walking towards it, some standing on the summit. — Gabal Al-Modawara – A Natural Sedimentary Record on the Edge of the Fayoum Depression Ahmed-M- Mohy

Close-up of a translucent, honey-yellow crystal with ridged, rough faces and yellow staining, held between the fingertips against a dark background. — Gypsum Crystal from the Qattamiya Area, Cairo – An Evaporitic Mineral Growth Ahmed-M- Mohy

Person in sunglasses with arms folded standing on a stone-paved terrace below a pale layered rock face with carved rectangular openings, beside a stone bench and steps. — Stratigraphic Section of Limestone and Shale Rocks in Upper Egypt Ahmed-M- Mohy

View from inside a pale rock cave whose arched mouth frames green fields, palm trees and a village on a wide flat plain under a blue sky. — Bat Cave Entrance in Hammamiya – Shale Formations Overlooking the Nile Valley Ahmed-M- Mohy

Close-up of a rock face of thin horizontal layers in white, cream and orange, cut by cracks. — Interbedded Sandstone and Shale Layers in Egypt’s Eastern Desert. Ahmed-M- Mohy

Person in dark overalls standing on a low outcrop of pale and reddish rock layers, touching the rock face, with broken blocks below and a blue sky. — Siltstone & Kaolinite Outcrop Metwally Hamza

Steeply tilted rock layers alternating dark brown and pale grey, their eroded edges forming jagged saw-toothed ridges like stylised mountains against a pale blue sky. — Stylized “mountains” of the Basque Coast Maela Baldan

Close-up of pale cream and brown fossil coral rock, its surface covered in tiny round pores and pitted with larger dark holes and cavities. — Fossilized Coral Reefs, Al-Naizak Crater Lake, Marsa Alam City, Red Sea, Egypt Metwally Hamza

Close-up of a brown and orange rock surface covered with many small white calcite crystals and dark pits, lit by a lamp in a dark space. — Calcite Crystals Occurred in the Pb/Zn Ores Depositional Environment as a result of the Hydrothermal Activity Metwally Hamza

Clusters of thin white needle-shaped calcite crystals growing from a brown rock surface in a dark, lamp-lit cavity. — Needles-like Calcite Crystals with Pb/Zn Ores Occurrence Metwally Hamza

Pale yellowish limestone layer overhanging darker grey, finely cracked shale below, with a floor of shale chips and stones under a blue sky. — Limestone and shale rock layers. Ahmed-M- Mohy

Person in a beige shirt standing with arms outstretched on a flat sandy desert plain scattered with hundreds of rounded pale boulders, with low eroded rocky hills behind. — DESERT BOULDERS (due to weathering processes in the region) Metwally Hamza

Ochre sandy outcrop annotated with coloured outlines around three pale rock blocks, white arrows showing opposite movement and a blue line tracing a wavy layer, with a rusty mine headframe on top. — Outcrop of S-shaped Stretching occurred in a layer of highly altered Limegrits Metwally Hamza

Layered roadside outcrop: grey-green crumbly upper layers over tan and cream bands, with a bright white crystalline layer at the base above dark gravel, and sunglasses for scale. — Outcrop of Calcite/Gypsum Deposits with Siltstone, Kaolinite, and Fanglomerates of the Red Sea Facies (EGYPT) Metwally Hamza

Gritstone edge of stacked flat rock slabs jutting over a steep green slope, with moorland, a road and distant hills under heavy grey cloud; the photo is digitally altered so only the greens keep colour. — Stanage Ridge (Peak District, UK) María Burguet

Close-up of white needle-shaped crystals sticking out of brownish sand, with a pair of black sunglasses lying on top for scale. — Needles-like Altered Gypsum Crystals within Lime and Sands Deposits Metwally Hamza
