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

open access: yesJournal 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.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

open access: yesBoreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Geomorphology of Tafi valley (Tucumán Province, Northwest Argentina)

open access: yesJournal of Maps, 2019
Tafí valley is an elongated tectonic basin of about 450 km2 located in NW Argentina in a mountainous frame of metamorphic and granitic Precambrian-Paleozoic rocks belonging to Sierras Pampeanas. This study presents the first detailed geomorphological map

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

open access: yesBoreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

INCEPTIVE TOPOGRAPHY OF FLUVIAL-DOMINATED RIVER MOUTH TERRACES: EXPERIMENTS

open access: yesDoboku Gakkai Ronbunshu, 2003
河川流が卓越する河口部を対象に模型実験を行い, 河口噴流における流速および浮遊砂濃度の分布構造, 掃流砂および浮遊砂による河口テラスの初期形成機構を明らかにした. また著者らの一部が提案した理論の妥当性を検証した結果, 理論と実験結果には良好な一致が認められ, 浮遊砂が支配的な場合, 噴流軸の両側に堆積が生じることが実験によっても示された. さらに河口テラスからデルタへの発達過程に関する実験を行い, 浮遊砂が支配的な場合, 掃流砂が支配的な場合とは明らかに異なる, 鳥趾状デルタに近い堆積形状へと発達することが示された.

AlpIce‐1: a database of geochronological and geomorphological constraints on Alps‐wide palaeoglacier fluctuations between the Last Glacial Maximum and the Holocene

open access: yesBoreas, EarlyView.
The AlpIce‐1 database is the first compilation of published geomorphological and geochronological markers constraining build‐up, culmination and decay of glaciers from the Last Glacial Maximum through the Holocene across the entire European Alps. AlpIce‐1 integrates more than 4200 surface‐exposure and radiocarbon ages, homogenized, quality controlled ...

Soil genesis in a marine terrace sequence of Sicily, Italy

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
Knowledge about the rates of pedogenic processes is essential to understand landscape development and history. It can be attained by the quantitative investigation of soil chronosequences.

Terrace springs: habitat haven for macrobenthic fauna in the lower plain of the River Ticino (Lombardy, Northern Italy)

open access: yesNatural History Sciences, 2018
Springs are important environments between hypogean and epigean habitats; the interaction between aquatic and terrestrial ecosystems is an important factor for their biotic communities.
