Survey of Diapirs and Diapirism: ABSTRACT
AAPG Bulletin, 1964Diapirs, sensu stricto, are bodies of sedimentary ma terial which have pierced (or appear to have pierced) overlying material as a result of their mobility at comparatively low temperatures. They are composed of evaporites, shales, mud, etc. and range in size literally from molehills to mountains and in age from Precambrian to Recent.

Geology Today, 2000
How are granite magmas transported from their source regions in the deep crust, through 10–40 km of overlying solid rock and emplaced close to the Earth's surface? What are the mechanical processes that allow this to take place and how long does it all take? These problems have challenged and preoccupied geologists since the days of Hutton.

Structural aspects of diapiric mélange emplacement: the Duck Creek diapir
Journal of Structural Geology, 1993Abstract The Duck Creek melange is one of a series of diapiric mud intrusions into the slope cover sequence of the Cascadia Accretionary Wedge. The diapir originated deep within the accreted Hoh sequences and has intruded approximately 1 km up into the 2–3 km thick Pliocene Quinault slope cover sequences at its current level of exposure in coastal ...

Abstract Not all finger-like diapirs evolve from or into linear walls as previously supposed. That would imply that all contemporaneous finger diapirs lie in rows and many do not. Physical models demonstrate that diapiric linear walls or rows of fingers have to be forced by lateral forces, lateral boundaries, or internal edge effects.

ABSTRACT:Until the last few years, diapirism reigned supreme among granitoid ascent mechanisms. Granitoid masses in a variety of material states, from pure melt through semi-molten crystal mushes to solid rock, were believed to have risen forcefully through the continental crust to their final emplacement levels in a way analogous to salt domes.

Clay Diapirism and Overthrust Faulting
Geological Society of America Bulletin, 1974The fluid-pressure hypothesis of overthrust faulting is extended in terms of stratigraphically controlled clay diapirism in the upper 2 or 3 km of a young, regressive marine sedimentary sequence. Such a sequence, with thick clay loaded by coarse clastic sediments, is mechanically unstable because the clay beds initially are undercompacted and have ...

In defense of magmatic diapirs
Journal of Structural Geology, 1999Abstract Diapirism as a crustal magma ascent mechanism has been recently criticized. We contend that this reflects an overly simplistic view that diapirs must resemble modeled hot-Stokes diapirs and the perception that magma ascent in dikes is a more problem-free mechanism for the construction of plutons.

Diapirism theory and experiment
Tectonophysics, 1972Abstract The application of fluid dynamics to layered systems with one or several flexible boundaries affected by gravity is reviewed. The theoretical equations are verified from models studied by the finite-element method and by experimental tests with liquid models.
