EXPERIMENTS SIMULATING SURFACE DEFORMATION INDUCED BY PLUTON EMPLACEMENT

Acocella V.; Mulugeta G. (2002)

We present centrifuge experiments to study the surface deformation induced by shallow pluton emplacement in a rheologically stratified crust. Sand simulates the topmost brittle crust; plastilina and denser silicone represent ...
FORMATION OF NONINTERSECTING NESTED CALDERAS: INSIGHTS FROM ANALOGUE MODELS

Acocella V.; Cifelli F.; Funiciello R. (2001)

Approximately 56% of 60 known nested calderas are pairs of nonintersecting subcircular structures with similar eccentricities. The consistent configuration suggests an interdependence in the formation of the two annular ...
THE CONTROL OF OVERBURDEN THICKNESS ON RESURGENT DOMES: INSIGHTS FROM ANALOGUE MODELS

Acocella V.; Cifelli F.; Funiciello R. (2001)

Resurgent doming consists of the uplift, usually accompanied by volcanic activity, of part of a collapse caldera. Analogue models were used to investigate the architecture of resurgent domes. Dry sand simulates the brittle ...
THE ROLE OF EXTENSIONAL STRUCTURES ON EXPERIMENTAL CALDERAS AND RESURGENCE

Acocella V.; Funiciello R.; Marotta E.; Orsi G.; de Vita S. (2004)

The structure and shape of collapses and resurgences is often controlled by pre-existing discontinuities, such as normal faults in rift zones. In order to study the role of extensional structures on collapse and resurgence, ...
