• The cover photo shows a "low-tech" producing well in the northern Salin Basin, Central Myanmar Depression, Myanmar. Small-scale production of oil from such wells, which may be drilled to depths of ~300 m or more, provides an important source of income for the local population. At this particular well, the dry leaves provide some shade for the operator. See the related paper on the geochemistry of oils from Myanmar by Bojesen-Koefoed et al. on pp 437-460 of this issue.

• The cover photograph shows a synclinal fold in thick Upper Jurassic carbonates above the town of Gunib, located in the central sector of the Terek-Caspian fold-and-thrust belt in south-central Dagestan (NE Caucasus). The town is of historical interest: the Caucasian War of the 19th century ended here in August, 1859. Photo by K. Sobornov.

• Obituary: John Ramsay, 1931-2021
• Cover photo: The cover photo shows a gorge nearly 300 m deep cutting through the Gornok anticline in the NW Zagros fold-and-thrust belt, Kurdistan Region of Iraq. The anticline, which extends for about 30 km along strike, portrays a mega back-kink in the layered Cretaceous carbonates of the Qamchuqa – Bekhme Formations. The kink occurs where gently SW-dipping layers in the forelimb of the fold (right) are bent to steep dips (~ 75° NE) in the back limb (left). Note the Bekhal waterfall (bottom left) which is located at the contact between the steeply-dipping layers of the Lower Cretaceous Qamchuqa Formation (to the right of the waterfall) and the Upper Cretaceous Bekhme Formation (to the left) characterised by extensive karst development and cavernous porosity. The peak (known as Sarakel) at the kink is at about 900 m above sea level. View is towards the SE; buildings for scale. Photo and caption courtesy of Hemin Koyi and Howri Mansurbeg.

• Cover photo: The photomicrographs on the cover show petrographic and diagenetic features (including cement generations and fractures) of bioclastic packstones from the Barremian – Albian "Urgonian" limestone succession in SE France. Controls on reservoir properties in these limestones are discussed by Cochard et al. in the paper on pp 97-114 of this issue. Photos by Jean Cochard.
