The Depositional Record, EarlyView.The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Distinct expressions of the BSR using various frequencies offshore Uruguay and its correspondence with the gas hydrate stability zone [PDF]
, 2011 At the Uruguayan continental margin, seismic evidence for the occurrence of gas hydrate has been identified based on the presence of BSRs in densely spaced 2D reflection seismic sections from different surveys.

The Depositional Record, EarlyView.Five large Alpine cave systems on the Dachstein (Austria) were investigated and 35 sediment profiles or outcrops between 860 m a.s.l. and 1945 m a.s.l. were analysed. An altitude‐dependent overall stratigraphy is established and depositional conditions and palaeo‐environments are reconstructed.

An Engineering Interpretation of Seismic Data [PDF]
Fall Meeting of the Society of Petroleum Engineers of AIME, 1968 ABSTRACT The reflection seismograph has long been the most important means for obtaining subsurface information prior to drilling. Interpretation of the seismic data is normally made by geophysicists to define subsurface structure. However, considerable information of great value to the drilling engineer is also contained in the seismic ...

Neural-networks for geophysicists and their application to seismic data interpretation [PDF]
The Leading Edge, 2019 There has been a surge of interest in neural networks for the interpretation of seismic images over the last few years. Network-based learning methods can provide fast and accurate automatic interpretation, provided that there are many training labels ...

The Depositional Record, EarlyView.Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Seismic performance of concrete tunnel–sand–pile interaction by the shake table test
Deep Underground Science and Engineering, EarlyView.This research presents the square root sum of squares response of displacements and tunnel moments under the Kobe and Loma Prieta seismic excitations with a peak ground acceleration of 0.05 g for various dry relative densities of local sand in Bangladesh.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
