DIAPIRIC SALT VOLUME OFFSHORE LOUISIANA

GEOPHYSICS, 1971
This short note reports that approximately 25,600 cubic miles of diapiric salt exists in offshore Louisiana to a water depth of 100 fathoms (Figure 1).

Internal Kinematics of Salt Diapirs

AAPG Bulletin, 1987
The internal structure of intrusive and extrusive salt bodies elucidates their external shape and the mechanism and history of diapiric emplacement--information relevant to petroleum exploration. Trace amounts of brine can act like heat to weaken salt and promote geologic creep by solution-transfer mechanisms.

Internal Kinematics of Salt Diapirs: DISCUSSION

AAPG Bulletin, 1989
Iklbot and Jackson (1987) presented a very good sum­ mary of several aspects of salt-stock configuration and emplacement as applied to the United States Gulf Coast. One aspect of this emplacement is a process they describe as "nested toroidal stream surfaces" (Iklbot and Jack­ son, 1987, p. 1083. their Figure 11) or toroidal flow.

Physical modelling of North Sea salt diapirism

Geological Society, London, Petroleum Geology Conference Series, 1993
Scaled analogue models provide a powerful tool for investigating progressive deformation. By varying experimental parameters it is possible to produce a wide variety of diapir morphologies and overburden responses. This paper describes the results of one of a series of experiments which investigates the geometry of overburden sediments around

The shaping of salt diapirs

Journal of Structural Geology, 1998
Abstract Six parameters shape the geometry of passive diapirs associated with stiff overburden: rates of salt supply ( S ′); dissolution ( D ′; sediment accumulation ( A ′); erosion ( Er′ ); extension ( E ′); and shortening ( Sh′ ). These parameters change in space and time, and hence influence the geometry of the structure as it forms.

Salt Diapirism in Southern Iran

AAPG Bulletin, 1974
More than 200 piercement salt plugs are present in southern Iran and in the Persian Gulf region. Recent investigations have shown the salt, the Hormuz Series, to be largely of Precambrian (late Proterozoic) age. The diapirs are famous for their tonguelike projections, known as "salt glaciers," and for their associated igneous, metamorphic, and ...

ALTERNATIVES TO HALOKINESIS IN SALT DIAPIRISM

Journal of Petroleum Geology, 1990
Over the past decade, and particularly in the last two or three years, there has been a change in the climate of thought on some aspects of salt geology and salt tectonics. Specifically, there has been a tendency to consider the development of many salt structures as being a result of non-halokinetic processes, in contrast to the strong emphasis placed

Three-dimensional Diffraction Response of Salt Diapirs

Proceedings, 2012
DEDICATED - Case Studies in Diffraction Imaging and Interpretation. We investigate the 3D diffraction response of the salt/sediment interface of salt diapirs using synthetic modeling and real data examples. The terminations of host rock layers against the flanks of a salt diapir are especially difficult to image using the seismic reflection method in ...

AN ADAPTIVE FINITE ELEMENT METHOD FOR MODELING SALT DIAPIRISM

Mathematical Models and Methods in Applied Sciences, 2006
Various types of oil traps have been found to be associated with salt domes in subsurface geology. In this paper the diapiric rise of light salt layers through a denser overburden — the surrounding rocks — is modeled assuming that, in a geological time scale, salt and rocks layers behave like Newtonian fluids. A Lagrangian approach is adopted to track

Zunyite Crystals in Salt Diapirs from Southern Iran

Rocks & Minerals, 2020
Blanford (1872) was the first to introduce the name “Hormuz Salt Formation” for a complex of rock salt and associated sedimentary and igneous rocks, exposed extensively on Hormuz Island (fig. 3).
