This paper discusses the results of Ion Beam Analyses (IBA) on 20 glass items excavated at the Late Iron Age site from Tinosu, Prahova County, Romania, broadly dated to the 2nd c. BC – 2nd c. AD. Most glass fragments originate from naturally colored or intentionally colored tableware, which were either monochrome (green or blue) or polychrome (mosaic ...

This paper provides a new facies model of gravelly cyclic steps that includes a facies model of lee side and variations deposited from hyperpycnal and surge‐type high‐density turbidity currents. Abstract Gravelly cyclic steps formed by turbidity currents have recently been widely recognised in the geological record.

This paper presents laboratory experiments that investigated the dynamics of mud‐grade calcite laden gravity flows, with the aim of determining how mobile these calciclastic flows are in comparison to fine‐grained cohesive and non‐cohesive siliciclastic gravity flows.

Two non‐seismically generated sedimentary volcanoes were excavated on the Colorado River delta in Lake Powell, Utah, USA, in order to characterise the internal structures. Sedimentary volcanoes are commonly employed as tools in palaeoseismic reconstruction, thus it is important to establish criteria to differentiate non‐seismic‐generated sedimentary ...
