Archaeometry, EarlyView.ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]
, 2013 The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is

Sedimentology, EarlyView.ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]
, 2011 Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Revised calendar date for the Taupo eruption derived by ¹⁴C wiggle-matching using a New Zealand kauri ¹⁴C calibration data set [PDF]
, 2011 Taupo volcano in central North Island, New Zealand, is the most frequently active and productive rhyolite volcano on Earth. Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the most violent eruption known in ...
