Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion
Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Abstract The geochemical heterogeneity of the mantle, recorded by mantle‐derived basalts, offers crucial insights into the evolution of mantle sources. However, recognizing mantle end‐members of basalts is challenging, as traditional trace element proxies yield ambiguous overlapping results in older basalts.

Water pathways and ancient lakes: Flowing towards new models to unravel the past
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

Early Pleistocene mixed arenites and their associated conglomerates and sandstones were studied in detail in Calabria, southern Italy. This study suggests that the studied palaeo‐strait was not necessarily a wider and similarly oriented expression of the modern Strait of Messina.

Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

Abstract The eastern Adriatic margin is composed by an Ocean‐Continent Transition lithosphere (OCT), resulting in the southwards along‐strike variation from collision to subduction. The Cephalonia‐Lefkada Transform Fault zone (CTF) is a right‐lateral strike‐slip fault system located above the OCT and associated to this kinematic transition.

We use palaeohydrology to quantify landscape‐scale geomorphic change in the Eocene Southern Pyrenean foreland. In response to hyperthermal events and tectonics during mountain‐building, rivers became suddenly steeper and faster, with enhanced water and sediment flux and a marked change in planform.
