Our analysis of tephra includes the morphology of glass, the mineral componentry, the abundance of glass-shards, lithics and minerals, and the composition of glass-shards in relation to the stratigraphy. Firstly, a reference database of glass compositions of known eruptions in the region was created to enable robust tephra correlations. One new correlation to the widespread H-1 eruption from Hudson volcano at 8.
The identification of sixty-five discrete deposits that were predominantly volcanic ashes glass and minerals with subtle characteristics of reworking in addition to three likely reworked tephra, and one unknown layer indicates that care must be taken in the analysis of both visible and invisible tephra layers to decipher their emplacement mechanisms. This research aims to improve the knowledge of the mid to late Holocene climate changes and the underlying drivers in the eastern Mediterranean.
These opposing and sometimes similar signals between NE and SW Peloponnese can be explained by the relative dominance of high-latitude atmospheric patterns over the peninsula. On the contrary, SW Peloponnese is dominated by warmer conditions during the same periods as the area is located on the lee side of the mountain and highly influenced by the adiabatic warming associated with the subsidence over the Eastern Mediterranean.
Cryptotephra deposits non-visible volcanic ash beds may extend thousands of kilometres and provide valuable chronological isochrons.
Here, we present a Lateglacial-early Holocene c. This period spans the last glacial termination across the southern mid-latitudes, a time period during which the palaeoenvironmental record is poorly resolved in southern South America and the South Atlantic. The development of a regional tephrostratigraphy will provide chronological constraint for palaeoenvironmental records from this period.
