An experimental study on water purification performance of modified volcanic rock ecological concrete [PDF]

Scientific Reports
Eco-concrete is an engineered porous material, often used in pervious pavement and slope protection. Volcanic rock, due to its loose and porous structure, can absorb pollutants and improve the performance of eco-concrete.

Multi-scale CT imaging technique characterization of volcanic rock reservoirs: a study case from the Changling fault depression of the southern Songliao Basin

Frontiers in Earth Science
The Changling fault depression in the southern Songliao Basin hosts volcanic rock reservoirs with significant oil and gas potential, yet their complex pore structures require advanced characterization to optimize resource exploration. To address this, we

Characteristics and controlling factors of volcanic clastic rock reservoirs in Wujiaping Formation of Upper Permian in northern Sichuan Basin

Shiyou shiyan dizhi, 2023
Under the influence of the Emei Taphrogenesis, a set of volcanic clastic rocks were developed in the Wujiapingian age of Permian in the northern Sichuan Basin. The lithology is highly heterogeneous, and the pore structure of reservoir is complex.

Thermodynamically consistent model for poroelastic rocks towards tectonic and volcanic processes and earthquakes [PDF]

, 2021
A general-purpose model combining concepts from rational continuum mechanics, fracture and damage mechanics, plasticity, and poromechanics is devised in Eulerian coordinates, involving objective time derivatives. The model complies with mass, momentum, and energy conservation as well as entropy inequality and objectivity.
