Ni laterites are considered worthy targets for critical metals (CM) exploration as Rare Earth
Elements (REE), Sc and platinum group elements (PGE) can be concentrated during …

Various durability tests require a drying step to remove free water without altering the
chemistry or microstructure of the materials. However, little is known about the effects of …

This paper presents a new balanced structural cross section of the Jaca thrust‐sheet‐top
basin of the southern Pyrenees combined with paleothermometry and apatite fission track …

Faults can represent adverse geological conditions that frequently cause the jamming of
tunnel boring machines (TBMs). In this study, we present a case study of TBM jamming at …

The anomalous enrichment of clay minerals in fault zones is considered a key factor
affecting the seismic behavior of faults, fault permeability, and mineralization. This process …

This paper studies the behavior of four different calcined clay-based geopolymers under
sulfuric acid attack and gives insights into their degradation mechanisms. Pastes were cast …

Since the 1980s, the Upper Jurassic lithographic limestone of the Causse Méjean (southern
France) has been known by local naturalists to yield fossils. However, until the beginning of …

Oscillatory compositional zoning in minerals has been observed in hydrothermal, magmatic,
and metamorphic environments and is commonly attributed to chemical or physical cyclical …

This study presents a mineralogical and mechanical analysis of the clay-rich materials and
structures identified in the Galera Fault Zone, southern Spain that formed as a consequence …

Thrusting at shallow depths often precludes analysis by means of structural indicators
effective in other geological contexts (eg, mylonites, sheath folds, shear bands). In this …
