Cyclic and dynamic behaviour of a soft pyroclastic rock

open access: closedGéotechnique, 2015
The mechanical behaviour under cyclic and dynamic conditions of a weakly cemented pozzolana, taken from the subsoil of a historical town in a seismically active area, was investigated through laboratory tests and in situ measurements. The geotechnical characterisation at laboratory scale is of particular importance as the small- and large-scale ...

Geotechnical characteristics of ignimbrite: A soft pyroclastic rock type

open access: closedEngineering Geology, 1993
Abstract The ranges of a variety of geotechnical properties encompassed by the ignimbrite lithology are established. Ignimbrites are of low density (1212–1928 kg m −3 ) and high porosity (18–51%), are very weak to weak in compression (0.23–54 MN m −2 ), have low tensile strength (0.12–7.1 MN m −2 ) and cohesion (0.06–9.0 MN m −2 ), yet the angle ...

U–Pb zircon geochronology of a pyroclastic rock from the Parsoi Formation, Mahakoshal Group: Implications towards age and tectonics of the Basin in Central Indian Tectonic Zone

Geological Journal, 2022
The Mahakoshal Group of rocks in the Central Indian Tectonic Zone (CITZ) holds the key to documenting the early events in the CITZ evolution and initiation of collision/accretion between the North and South Indian cratons (NIC, SIC).

Physical and structural properties of a pyroclastic soft rock

open access: closed, 1998
The subsoil of a large area surrounding the city of Rome (Italy) consists mainly of pyroclastic deposits originated from the explosive activity of the Colli Albani volcanic complex. This paper focuses on a type of pyroclastic soft rock, locally known as Pozzolana Nera. The structural features of the deposit are presented in the paper.
