Material-specific coefficients C1 and C2 in Williams-Landel-Ferry equations and phase transition behaviors of asphalt binder reinforced by various basalt fibers

Case Studies in Construction Materials
The Williams–Landel–Ferry (WLF) equation is critical for predicting the rheological behavior of viscoelastic materials. However, no research has reported the main parameters, C1 and C2, in WLF equations for fiber-reinforced asphalts (FRAs).

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, EarlyView.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

The local paleoenvironment of Kalavan‐2 based on small‐vertebrate remains and its implications for human‐environment‐dynamics between 60 and 35 ka in the Armenian Highlands

Journal of Quaternary Science, EarlyView.
ABSTRACT Kalavan‐2, a high‐altitude (∼1640 m a.s.l.) open‐air site in Armenia, preserves stratified Middle Paleolithic occupations with a rich small‐vertebrate record. Luminescence dating has placed site formation between ~60 and 45 ka, but without independent chronological control of the microvertebrate accumulation.

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

Journal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Effect of the vintage year on strontium isotopic ratio (87Sr/86Sr) of wines: a Portuguese case study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Currently, there is a growing need for wine authenticity tools to face the global wine market and deal with adulteration cases. Stable isotope analyses, recognized by the Organization of Vine and Wine as a tool for detecting authenticity fraud, form the basis of the European Wine Databank, which faces limitations concerning the ...
