X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, EarlyView.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Revealing the pace of river landscape evolution during the Quaternary: recent developments in numerical dating methods [PDF]

, 2016
During the last twenty years, several technical developments have considerably intensified the use of numerical dating methods for the Quaternary. The study of fluvial archives has greatly benefited from these enhancements, opening new dating horizons ...

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

Sedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Aeolian and Biogeochemical Transformations of Detrital Gold Morphology in the Pool Burn Basin, Central Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Pool Burn basin is a tectonic depression that became almost isolated from the regional drainage system by river reorientation during Pleistocene uplift of surrounding ridges. Consequently, detrital gold in the basin was largely locally derived, from supergene zones on orogenic deposits and recycled from paleoplacers in erosional remnants of Miocene

Stratigraphy of Fluvial Terraces in the North Uonuma Hill, Niigata Prefecture

Journal of the Japan Society of Engineering Geology, 2006
現在, われわれは2004年新潟県中越地震震源地付近の第四紀後期の地殻変動について検討を進めている. 本稿では, 魚沼丘陵北部に分布する河成段丘層序の調査結果を速報し, さらに, 魚沼丘陵東縁の六日町盆地西縁断層の活動性に触れる. 調査地域に分布する河成段丘は, 空中写真判読調査により, 高位より, Hf, Mf, Lf面に区分される. さらに, Hf面はHf 1～3面に, Lf面は, Lf1～4面に細分される. 続いて, 火山灰層序に基づいてこれらの編年を行った. Hf 3面は海洋酸素同位体ステージ (MIS) 6よりも古く, MIS 8に対比される可能性がある. Mf面はMIS 6に対比される可能性が高い.

Newly Discovered Active Faults in the Wairarapa Valley: Implications for Multi‐Fault Rupture and Kinematics in the Southern North Island, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Active fault locations and constraints on the timing and size of earthquakes are important for understanding and mitigating seismic hazard in Aotearoa New Zealand. However, historical and instrumental records are too short to provide these data on most earthquake‐generating faults. Light detection and ranging (lidar) data provide us with the ability to

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, Volume 12, Issue 1, February 2026.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.
