Bayesian classification for dating archaeological sites via projectile points [PDF]
arXiv, 2020 Dating is a key element for archaeologists. We propose a Bayesian approach to provide chronology to sites that have neither radiocarbon dating nor clear stratigraphy and whose only information comes from lithic arrowheads. This classifier is based on the Dirichlet-multinomial inferential process and posterior predictive distributions.

Stratigraphic and sedimentologic framework for tephras in the Wilson Creek Formation, Mono Basin, California, USA [PDF]
, 2018 Numerous tephra layers occur within the late Pleistocene Wilson Creek Formation, where they are interbedded with lacustrine deposits of Lake Russell, the ancestor of present-day Mono Lake. Most of the tephra layers are rhyolitic in composition, and were produced from the Mono Craters.

Stratigraphy of the Hawai'i Scientific Drilling Project core (HSDP2): Anatomy of a Hawaiian shield volcano [PDF]
, 2007 The Hawai'i Scientific Drilling Project (HSDP2) successfully drilled ∼3.1 km into the island of Hawai'i. Drilling started on Mauna Loa volcano, drilling 247 m of subaerial lavas before encountering 832 m of subaerial Mauna Kea lavas, followed by 2019 m ...

Archaeological Prospection, EarlyView.ABSTRACT This study presents a comprehensive approach to verifying a presumed western gate at Pohansko by integrating nondestructive geophysical methods (ERT, magnetometry and core prospection) with traditional archaeological excavation. The identification and characterization of gates by nondestructive methods within early mediaeval fortified sites ...

Dating glacier ice of the last millennium by quantum technology [PDF]
, 2018 Radiometric dating with 39Ar covers a unique timespan and offers key advances in interpreting environmental archives of the last millennium. Although this tracer has been acknowledged for decades, studies so far have been limited by the low abundance and radioactivity, thus requiring huge sample sizes.

Archaeological Prospection, EarlyView.ABSTRACT At the Huacas de Moche (HdM), one of the most prominent archaeological sites in Trujillo, Peru, the needs of an expanding modern community are in direct conflict with the desire to preserve the wealth of archaeological information. The undetermined extent of the HdM site introduces disputes in land usage where potential archaeological features

Near Surface Geophysics, Volume 20, Issue 6, Page 637-660, December 2022., 2022 ABSTRACT In mineral exploration, reliable and comprehensive petrophysical groundwork helps evaluate the success rate of applying geophysical methods to the target and thus improves the quality of decision‐making related to geophysical surveys. Petrophysical data for potential field exploration can be efficiently collected from drill cores together with

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]
, 2015 During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.
