This research is a contribution to the mineralogical and physical–mechanical
characterisation of the ignimbrites from Arucas (Gran Canaria Island), used as building …

The objective of this study is to evaluate the petrophysical properties of four ignimbrites
employed as dimension stones. The natural stone under study is produced in Tenerife …

In volcanic terrains and in particular island regions, the aggregates come from the
mechanical crushing of lava rocks and pyroclastic deposits. This study offers an …

Abstract The Permian San Pedro Cu-(Mo) deposit consists of a porphyry system with
associated polymetallic veins in the San Rafael Massif, Argentina. This deposit resulted from …

Welding of pyroclastic deposits to reform a coherent rock mass is a common phenomenon,
especially for pumiceous pyroclastic density current deposits (ie, ignimbrites). However, and …

[EN] This paper analyses the engineering geological properties of the rocks and soils of the
Canary Islands based on data from field studies, laboratory tests and extensive databases …

The aim of this research work was to determine and analyse the mechanical properties of a
group of four varieties of ignimbrites, which are differentiated according to their colour …

Cut slope surfaces are affected by excavation activities and weathering agents.
Disturbances on the surface can penetrate down to a certain depth. Slope stability analyses …

The Arteara rock avalanche is developed in the Fataga Group which is related to the first
volcanic stage in the Gran Canaria Island (8.6–13.3 Ma). The materials of the avalanche are …

Este artículo establece un marco general sobre la utilización de los materiales volcánicos,
describe el comportamiento geotécnico habitual de estos materiales, ya sea en zonas de …
