Taking machine learning with a grain of sand: Sediment Analysis Neural‐network Data‐engine (SAND‐e) reveals sedimentological differences between turbid and clear‐water reefs

The Depositional Record, EarlyView.
Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, EarlyView.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]

, 2010
The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,

Organoclay interaction response to sedimentary environment and sources in Paleogene shales from the Nanpu Sag: Insights for organic matter accumulation mechanism

The Depositional Record, EarlyView.
The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

Investigating the Structural Geology Control of the Opak Fault on the Semilir Formation in Yogyakarta

LITHOSPHERE (Russia)
Research subject. The hill morphology formed in the study area, which is part of the Semilir Formation, is suspected to be a product of Opak fault reactivation. Further investigation is needed to substantiate this claim.Aim. To investigate the characteristics of the Opak Fault in the Semilir Formation.

Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

Deep Underground Science and Engineering, EarlyView.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...
