Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

Active Layer Warming and Thickening on CALM‐S JGM, James Ross Island, in the Period 2013/14–2022/23

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Circumpolar Active Layer Monitoring‐South (CALM‐S) site was established near the Johann Gregor Mendel (JGM) research station on James Ross Island in February 2014. The CALM‐S JGM grid, measuring 80 × 70 m, encompasses two distinct lithological units: a Holocene marine terrace (covering approximately 75% of the grid) and Cretaceous ...

Environmental Conditions in the Late Pleistocene at the Southern Margin of the European Periglacial Domain (Hungary) Inferred From Quartz Grain Microtextures

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The paper investigates environmental conditions prevailing at the southern margin of the European periglacial domain in NW Hungary (Kemeneshát area) during the Late Pleistocene. Samples of sediments infilling sand wedges and their host sediments were analyzed by examining the grain‐size distributions, as well as the morphology and ...

Lead isotopes may link the earliest silver hoard from Megiddo to the military campaign of Thutmose III

Archaeometry, Volume 67, Issue 2, Page 380-398, April 2025.
Abstract During the University of Chicago excavations at Megiddo, a 135 g hoard of silver fragments wrapped in cloth and enclosed in a small clay jug was unearthed in a room with an earthen or plastered floor, in a focal point of the Middle Bronze (MB) city. It was affiliated by the excavators with Stratum XIIIA, dated to the MB I.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Advancements in radiocarbon dating: An overview of its impact on Mexican archaeology

Archaeometry, EarlyView.
Abstract In this article, we provide a concise historical summary tracing the evolution of radiocarbon dating techniques in Mexico and Central America. We explore the contributions of early pioneers who first employed radiocarbon dating methods, leading to the establishment of a Mexican accelerator mass spectrometry laboratory. The study highlights its
