Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Fluvial terraces along the Tama River, Kanto district.

The Quaternary Research (Daiyonki-Kenkyu), 1990
The Tama River flows from the Kanto Mountains, 1, 000 to 2, 000 meters high, and across the Kanto Plain into Tokyo Bay. Fluvial terraces from the Late Pleistocene are well developed along the river. They are classified into four groups according to the differences in the relative height above the river floor and in the tephra-cover.

Vertical slip rates of active faults of southern Albania inferred from river terraces

Annals of Geophysics, 2014
Fluvial terraces of Shkumbin, Devoll, Osum and Vjosa rivers (southern Albania and northwestern Greece) are studied in order to quantify the vertical slip rates of the large active faults of the Dinaric-Albanic-Hellenic Alpine fold belt.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

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.

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

Boreas, EarlyView.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Revised classification of glaciofluvial landforms in the Finnish sector of the Fennoscandian Ice Sheet

Boreas, EarlyView.
Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

INCEPTIVE TOPOGRAPHY OF FLUVIAL-DOMINATED RIVER MOUTH TERRACES: EXPERIMENTS

Doboku 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.
