Introduction to Sedimentary Evidence

Geomorphic and sedimentary evidence for the flood includes streamlined boulder-strewn bars, gravel dune fields, and terraces sloping up Fraser and lowermost Thompson valleys, opposite the present direction of current river flow.

Although the tectonic evolution of the PAO has been discussed from diverse perspectives, the spatiotemporal dynamics in the evolution of the main branch of the PAO and its relationship with the Tethys remain contentious partly because of the absence of sedimentary evidence.

Sedimentary evidence from the upper Wuchiapingian-mid Induan Wutonggou LC indicates that the climate was generally humid-subhumid and gradually became variable toward a seasonally dry condition in early Induan.

We found sedimentary evidence of the 2015 and one previous tsunami as tabular sand sheets.

Based on sedimentary evidence, the dynamic evolution of the rockslide in response to temperature changes were reconstructed based on frictional thermal analysis.

3, 2 h apart), and it provides the first unmistakable sedimentary evidence for an earthquake doublet.

</p><p>Overall, this work has provided the sedimentary evidence of modern climate change through robust observational sediment flux data over multiple decades.

We suggest this time period can be considered as a start point for the Anthropocene based on the sedimentary evidence of closed basins, globally.

Based on the sedimentary evidence and known environmental constraints at the time, we develop a glacial scenario that explains how these ice sheets, together with eustatic sea-level changes, may have affected the past oceanography of the Arctic Ocean in a fundamental way that must have led to a drastic and non-linear response to external forcing.

Sedimentary evidence indicates that the fallout tuff was variable reworked locally, whereas the tuffaceous siltstones are interpreted as turbidites mixed with terrigenous material derived from Anatolia.

Large-scale geodynamic processes not only result in magmatism, but also generate corresponding tectonic and sedimentary evidence.

Our findings provide robust molecular sedimentary evidence confirming that the environmental evolution of lakes in the Yunnan–Guizhou Plateau over the past century was closely associated with enhanced anthropogenic activities.

Well-preserved shoreline and terrace remains surrounding these lakes provide critical geomorphological and sedimentary evidence that can be used to infer past lake levels over geological timescales.

However, under-estimation of run-up persisted requiring further consideration of palaeotopography and palaeo-near-shore bathymetry for it to agree with sedimentary evidence.

Sedimentary evidence for enhanced volcanic eruption during the glacial/interglacial transition in the volcanically active mid-ocean ridges is still lacking.

This study presents detailed morphological and sedimentary evidence from six esker systems in north-central Ireland, where adjacent and interacting ice domes were characterized by changes in ice-bed thermal and hydrological properties as well as significant ice dome centre migration.

This morphosedimentary evidence is associated with MIS 5−2 sea level fluctuations.

Sedimentary evidence and morphological analysis of cross sections along the LLDL outlet channel revealed a larger, earlier lake with a total volume of 4.

Paleofloods are flood events that occurred prior to instrumented records that are discerned from sedimentary evidence.

Geochemical and sedimentary evidence suggests that these S-isotope anomalies were transferred from the paleo-continent under an oxygenated atmosphere.

The sedimentary evidences of the Mungaroo Formation show low-angle shingled progradational seismic reflection configuration.

Here we present sedimentary evidence (cyclone overwash deposits, beachrock boulders, and cyclone-induced clastic deposits) of historic large cyclone events from coastal dune deposits on eastern Hainan Island, China.

2012), but without sedimentary evidence in the neighbourhood of the present Ougarta Range except for Hirnantian periglacial sediments.

In this paper we therefore firstly present a new set of criteria for identifying the landform and sedimentary evidence that defines and characterises ice-marginal lakes.

In the third part of the chapter, an analysis of the best-documented flood-rich periods and flood peaks, namely the late 1330s–1350s, late 1390s–early 1440s and late 1470s–1520s, is presented in more detail, in combination with related documentary and sedimentary evidence.

The inter-sample variability of age spectra of the Triassic samples provides sedimentary evidence for Indosinian tectonic reactivation in the Eastern Tianshan and its periphery, which could be attributed to differential exhumation of different sources driven by coeval strike-slip tectonics along deep faults.

This PhD research utilises, for the first time, sedimentary evidence for mid to late Quaternary environmental change in the Tequixquiac region of Central-eastern Mexico.

Our knowledge of this impact can be improved by correlating long-term historical storm records with sedimentary evidence of storm surges, but so far few studies have applied such an approach.

Largest in quantity, potential river flood changes, great and extraordinary floods, flood-rich periods, mainly those occurred on the Danube and partly on other rivers, are discussed, detected predominantly in archaeological and partly in sedimentary evidence.

This is followed by an overview of major medieval hydroclimatic shifts and break points detected in sedimentary evidence in different parts of Europe, with an emphasis on Central Europe,regarding lake/mire water-level changes, variability and changes in the frequency and intensity of floods captured in lake sedimentation and in river alluvia.

Sedimentary evidence provided by foraminifera, diatoms, testate amoebae and marine macrofossils is used to support the evidence provided by the landforms in order to assess changes in former sea levels.
