The Bossòst dome is an E–W-trending elongated structural and metamorphic dome developed in Cambro-Ordovician metasedimentary rocks in the Variscan Axial Zone of the central Pyrenees. A steep fault separates a northern half-dome, cored by massif granite, from an E–W-trending doubly plunging antiform with granitic sills and dykes in the core to the south. The main foliation is a flat-lying S1/2 s...

Several properties within the eastern Eyre Mountains are currently undergoing tenure revue. This report provides geological information relevant to these reviews, particularly on the sequence of glacial deposits south from Kingston. The geology of the Eyre Mountains is dominated by low-grade metasedimentary rocks of the Permian Caples terrane, becoming increasingly schistose toward the northeas...

We present integrated structural, petrological, mineralogical and geochemical investigations conducted on an exhumed hydrothermal system identified in Terre-de-Haut Island (Guadeloupe archipelago). This work demonstrates, for the first time, occurrence of ductile shear zones, marked by development spaced schistosity planes generated pressure-solution processes. unravel that is coeval with high-...

Lichen mosaics on different-textured schists located in the Coa Valley (Portugal) and Siega Verde (Spain) archaeological sites were cleaned using different chemicals, namely ethanol (50% v/v distilled water), benzalkonium chloride (3% v/v) or Biotin T® v/v), Nd:YAG laser wavelengths (1064 nm 266 nm). The surfaces evaluated 24 h 4 years after cleaning to determine its durability colour spectroph...

The internal structure of a rock is determined by its empty spaces (pores and cracks), which can evolve over time chemical, physical, or biological processes. In construction, these chemical physical processes, their effects in the final products, known as aggregates, are well known, controlled to estimate quality durability. However, intrinsic properties raw material, rock, processes that affe...

The Ellsworth belt is one of several fault-bounded blocks exposed along the southeastern coast Maine that formed within Ganderia. New ID-TIMS U–Pb geochronological data integrated with field relationships provide additional insights into timing magmatism and deformation in belt. deformed Lamoine Granite was selected for zircon analysis to: (i) establish protolith age; (ii) direct temporal const...

Background. In this paper, the authors aim to reveal localization patterns of gold mineralization in Phuok Son region Central Vietnam, which formed a Proterozoic-Cambrian metamorphic complex zone Late Paleozoic Benzhang–Queshon granite block. Aim. To determine Phuoc area, Vietnam. Materials and methods. The research was based on geological materials, as well mine working appraisal data. materia...

Several physical parameters and anisotropy related to rock textural arrangements, schistosity weakness planes such as cracks joints affect the P-wave velocity (VP). First, VP of quartz-mica schist a common type widespread metamorphic was compared with jointed homogeneous limestone specimens clarify effect these two different types anisotropies. The results showed that texture is stronger than l...

Abstract The Paleoarchean Mt Edgar dome in the East Pilbara Terrane has long been studied as an archetypal within Archean dome‐and‐keel terranes, but history of its formation is debated. Kinematic data presented this study provide new insights into late‐stage development and Terrane. Quartz crystallographic preferred orientation (CPO), optical microstructures, field structures all indicate that...
