M. Manga (1997) Interactions between mantle diapirs,
submitted to Geophysical Research Letters.
Experimental, theoretical and numerical results are presented
for the dynamics of interacting and deforming diapirs.
The clustering, or ``collective hydrodynamics'' of diapirs
is due to the deformation induced by their mutual interactions.
The merging of two diapirs can occur relatively rapidly compared to
their ascent time through the mantle. However, clustering of
many diapirs in ``clouds'' of diapirs is a relatively slow process
and unlikely to significantly affect their distribution in the Earth's mantle.
On Venus, if
coronae are produced by diapirs, then the inferred
diapir radius is smaller the plume head diameter in the
Earth, and diapir clustering may explain the variation of coronae size
and may be related to the observed clustering of coronae on
