In a ‘source to sink’ sedimentary system, multiple processes have the potential to modify the sediment composition during sediment generation at the source, through transport, deposition and burial. To investigate these issues, a multi-proxy provenance study of deep-water and shallow-marine sandstones from the mid-Carboniferous Clare Basin was undertaken, utilising zircon and apatite U-Pb geochronology, heavy mineral analysis (including apatite trace element data) and petrography. Data from the deep-water submarine fans show a similar provenance signal to the shallow marine sandstones. Data, from across the Clare Basin stratigraphy indicate sands were likely and consistently derived from the south and SW, with a portion of the detritus being recycled from Old Red Sandstone basins to the south. The provenance signal, however, shows spatial and temporal variations across the basin that are explained by fluctuations in the amount of recycled sediments and are linked with the evolving Variscan Orogenic Belt. Heavy mineral data from both shallow marine and deep-water sandstones suggest a basin configuration with a delta system feeding directly into the deep basin.Supplementary material:

The geochemistry of detrital rutile grains, which are extremely resistant to weathering, was used in a provenance study of the transgressive Albian quartz sands in the southern part of extra-Carpathian Poland. Rutile grains were sampled from eight outcrops and four boreholes located on the Miechów, Szydłowiec, and Puławy Segments. The crystallization temperatures of the rutile grains, calculated using a Zr-in-rutile geothermometer, allowed for the division of the study area into three parts: western, central, and eastern. The western group of samples, located in the Miechów Segment, is characterized by a polymodal distribution of rutile crystallization temperatures (700–800 °C; 550–600 °C, and c. 900 °C) with a significant predominance of high-temperature forms, and with a clear prevalence of metapelitic over metamafic rutile. The eastern group of samples, corresponding to the Lublin Area, is monomodal and their crystallization temperatures peak at 550–600 °C. The contents of metapelitic to metamafic rutile in the study area are comparable. The central group of rutile samples with bimodal distribution (550–600 °C and 850–950 °C) most likely represents a mixing zone, with a visible influence from the western and, to a lesser extent, the eastern group. The most probable source area for the western and the central groups seems to be granulite and high-temperature eclogite facies rocks from the Bohemian Massif. The most probable source area for the eastern group of rutiles seems to be amphibolites and low temperature eclogite facies rocks, probably derived from the southern part of the Baltic Shield.

AbstractWe present the results of a detailed geochemical provenance study of 54 Natufian (ca. 15,000–11,700 cal. BP) basalt pestles from the site of el-Wad Terrace (EWT), Israel. It is the first time precise locations from where basalt raw materials were derived are provided. The results indicate that the Natufian hunter-gatherers used multiple sources of basaltic rocks, distributed over a large area surrounding the Sea of Galilee. This area is located at a considerable distance from EWT, ca. 60–120 km away, in a region where contemporaneous Natufian basecamps are few. We consider two possible models that suggest vehicles for the transportation of these artifacts to EWT, namely the exchange obtaining model (EOM) and the direct procurement model (DPM). We argue that these mechanisms are not mutually exclusive and may have operated together. We also suggest that at a time of increasing Natufian territoriality, a large area around the Sea of Galilee remained unclaimed. The paper concludes with a brief discussion of the implications for the two models. In particular, we note that the DPM implies that technological know-how for pestle production was maintained within the EWT community.

A continuous Late Cretaceous-Paleocene sedimentary succession within the India-Asia collision suture zone in Xigaze, Tibet, contains a c. 80 m thick sand injection complex immediately overlain by a c. 60 m thick mass transport deposit (MTD, the first of several) with the first evidence of Asian provenance, and immediately followed by a ∼61 Ma tuff. The youngest in situ strata with unequivocal Indian provenance are probably the source beds of the sand intrusions, separated from the first MTD by c. 50 m of pelagic deposits that potentially represent an interval of several million years; the collision could thus have occurred at any time within this interval. However, the uppermost limit of the sand intrusions closely coinciding with the MTD suggests that they occurred penecontemporaneously, possibly associated with initial continental collision. This may provide additional constraint of initial collision onset at c. 61 Ma. Co-occurrence of MTDs and sand injections are possibly good sedimentary indicators of continental collision onset and characteristic of syn-collisional trench basins. Since neither the youngest Indian nor the oldest Asian provenance sediments are in their original stratigraphic position, this study shows that detailed sedimentological work combined with provenance study can better constrain the timing of continental collision.
