Maars to calderas. End-members on a spectrum of explosive volcanic depressions [PDF]
, 2015 We discuss maar-diatremes and calderas as end-members on a spectrum of negative volcanic landforms (depressions) produced by explosive eruptions (note—we focus on calderas formed during explosive eruptions, recognizing that some caldera types are not ...

Application of continuous lithologic models in the identification of pyroclastic rocks
IOP Conference Series: Earth and Environmental Science, 2021 The lithologic profile of pyroclastic rock is based on the sedimentary environment of multiple sources, which has the characteristics of lithologic grain variation of continental clastic rock and the characteristics of rock composition from different sources.

Stiffness of pyroclastic scoriae under different degrees of saturation [PDF]
E3S Web of ConferencesPyroclasts are natural materials formed during volcanic eruptions, characterised by low densities due to their high porosity, which results in reticular, vesicular or mixed internal structures.
