Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone
Journal of Quaternary Science, EarlyView.ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland [PDF]
, 1993 Old Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over ...

Geostandards and Geoanalytical Research, EarlyView.Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

The walls boundary fault zone and the MØre TrØndelag fault complex:: a case study of two reactivated fault zones. [PDF]
, 2001 It is commonly observed that ancient faults or shear zones can become reactivated again and again, either within the same or even superimposed tectonic episodes, yet millions of years apart.

Insect Molecular Biology, EarlyView.Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Symbiosis in Late Devonian-Mississippian corals: a review
, 2017 There are four symbiotic associations involving corals known from the Late Devonian. Corals formed at least six symbiotic associations in the Mississippian, most of which involved crinoids. There was an escalation in the abundance and complexity of coral
