DATING PALEOSOL AND ANIMAL REMAINS IN LOESS DEPOSITS [PDF]

, 2006
Accurate and reliable dating of paleosols, animal remains, and artifacts is of crucial importance in reconstructing environmental change and understanding the interrelationship between human activities and natural environments. Dating different materials

Effects of Straw Incorporation and Tillage Depth on Soil Quality in Mollisol Profiles

Land Degradation &Development, EarlyView.
ABSTRACT Although improvements in soil quality under straw incorporation have been well documented, responses across soil profiles under different tillage depths remain unclear. To address this issue, a field experiment was established in 2011 in Mollisols with conventional tillage (20 cm depth) without straw (CT) and with straw (SCT), no tillage with ...

Intra-conference and Post-conference Tour Guides, International Inter-INQUA Field Conference and Workshop on Tephrochronology, Loess, and Paleopedology [PDF]

, 1994
New Zealand consists of a cluster of islands, the three largest being North, South, and Stewart, in the southwest Pacific Ocean. They have a total land area of about 270 000 km2 (similar to that of the British Isles or Japan).

Magnetic stratigraphy constraints on the Matuyama-Brunhes boundary recorded in a loess section at the southern margin of Chinese Loess Plateau

, 2016
Although the Matuyama-Brunhes boundary (MBB) in the Chinese Loess Plateau (CLP) is very important in reliably correlating Quaternary loess with other sediments in the world, particularly with marine and polar ice cores, its exact stratigraphic position ...

Paleoclimatic significance of mineral magnetic properties of loess sediments in northeastern Qinghai-Tibetan Plateau

, 2003
Loess deposit in the northeastern Qinghai-Tibetan Plateau offers an excellent record of climate and environment changes in this region. We have conducted multiparameter mineral magnetic analyses of samples of loess deposits from the Dongchuan, Lalakou ...

Macro–Micro Correlation Mechanism Between Structural Potential and Mechanical Strength in Collapsible Loess

Buildings
The collapsibility of loess in the northwest region poses a significant threat to infrastructure stability. Current research predominantly separates macroscopic mechanical behaviour from mesoscopic structural characteristics, lacking a systematic ...

Tracking potential source areas of Central European loess:examples from Tokaj (HU), Nussloch (D) and Grub (AT)

Open Geosciences, 2015
There are several competing hypotheses for theorigin of loess in Europe but quantitative evidence is stillrare. Here, Sr-Nd isotopic and bulk elemental compositionof loess from Marine Isotope Stages 2 and 3 fromthree study regions in Central Europe ...

Trade‐Offs and Synergies in Cultivated Land Multifunctionality and Zoning Management in the Dongting Lake Region: A Multiscale Analysis

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the multiscale patterns and interactions of cultivated land multifunctionality is important for conservation, governance, and agricultural spatial optimization in the Dongting Lake region. Using 2020 data, we evaluated economic production (EPF), social security (SSF), landscape‐based recreation (LRF), and ecological maintenance ...

Analysis of crack development in loess deep filled ground based on physical modelling tests

Zhongguo dizhi zaihai yu fangzhi xuebao
Cracks are a common issue in deep filled construction projects, and conventional methods often struggle to accurately predict their development. To guide the anti-crack design for deep-filled loess projects, a prototype of a typical gully section from a ...
