The diapiric process and glaciotectonic disturbances may have been favoured by altitude differences in the Viru plateau and at the bottom of the Gulf of Finland, which generated the change of load and increase in the pressure on the edge of the ice cover.
Diapiric cavities commonly contain calcite alone or in combination with prehnite.
However, research indicates that magmatic modal layers may originate through many other processes (Naslund and McBirney 1996), including, for example, diapiric ascent and synmagmatic deformation (e.g., Ameglio et al.
For example, volcanic centres in the Central American arc are typically spaced about 25 km apart, and are thought to be the result of diapiric uprise from a larger pool of magma that parallels the length of the arc (Marsh 1979; Gill 1981).
Thirty-four of the whale sharks sighted were in close proximity to relatively small, high relief diapiric features dominated by coralline algae (Rezak et al., 1990); Ewing Bank (28[degrees]06'N, 91[degrees]02'W), Bright Bank (27[degrees]53'N, 93[degrees]18'W) and 28 Fathom Bank (27[degrees]55'N, 93[degrees]26'W).
The seismic profiles contain a section of uniformly bedded sediments, and apparently deep seated diapiric features.
Most Maykopian outcrops are tied with phenomena of diapirism, which have caused the deposits to be in the surface or down along the kernels of numerous diapiric folds.
Coal in the Sangatta area is sub-bituminous, except for the higher rank coals mined by Kaltim Prima over the Pinang Dome (a diapiric dome).
Most Maykopian out-crops are tied with phenomena of diapirism, which have caused the deposits to be in the surface or down along the kernels of numerous diapiric folds.
A salt diapiric dome was documented as well, not reported by any previous worker.
Evaporites of the Windsor Group form diapiric structures in many areas (e.g., Boehner 1992; Durling et al.
Many scientists think that hotspots mark locations where diapiric convection cells, called mantle "plumes", rise beneath lithospheric plates (Morgan, 1971; Wilson, 1973).
