On central western Axel Heiberg Island, which lies across the axis of the Sverdrup Basin, there are about forty diapirs composed of Lower Pennsylvanian anhydrite and microfossiliferous limestone. Inclusions of foreign sedimentary rock are extremely scarce.

exposed at surface. Of these, Axel Heiberg Island hosts 46 exposed diapirs (Embry ). In consequence, Axel Heiberg Island contains one of the highest concentrations of salt diapirs in the world, second only to the Zagros Mountains of Iran. The diapirs on the island are composed of anhydrite, which is weathering to gypsum, and contain interbeds.
A reoccurring theme, the outcrops show some exposures of intact rock salt, but the majority of the surface has weathered into the highly vuggy gypsum crust that is characteristic of the Axel Heiberg Island anhydrite diapirs. Part way up the valley wall, the anhydrite is interbedded with what I.
Axel Heiberg Island (northern Nunavut) contains the thickest Mesozoic section in Sverdrup Basin. The approximately km long island is second only to Iran in its concentration of exposed diapirs.
Forty-six diapirs of Carboniferous evaporites and associated minibasins are impressively exposed on the island. Approximately diapirs have been found within the basin, of which 60 are exposed at surface.
Three quarters of exposed diapris within the basin are located on Axel Heiberg Island. The diapirs composed of anhydrite, which is weathering to gypusum, and contain interbeds of. formation. The domes are composed of a m thick anhydrite-dominant layer underlain by a halite diapir core of unknown thickness.
The initiation and rate of vertical migration of the diapirs are poorly constrained due to the lack of high quality seismic imaging, particularly at depths of km where the source layer is thought to occur. Open Library is an open, editable library catalog, building towards a web page for every book ever published.
The cores are surrounded by Mesozoic rocks.A geometric analysis of two well-exposed domes on Axel Heiberg Island was made to learn whether the anhydrite behaved as an active source material or as.

The main objective of this activity, from tois to identify areas on Axel Heiberg Island and Ellesmere Island that show a high potential for Ni-Cu-PGE deposits (Figure 1). Specific activities include (1) detailed mapping of sills and dykes not included in current scale. Axel Heiberg Island (Nunavut Territory) contains the thickest Mesozoic section in the Sverdrup Basin, and the ~km-long island is second only to Iran in the number and concentration of exposed evaporite diapirs.
However, local geology and tectonic history have hardly been studied. The perennial springs in Axel Heiberg Island are known for half a century and have been extensively described in the literature.
Discharging spring waters are hypersaline ( molal NaCl; ~5 to 19 wt% NaCl) and precipitate Fe-sulfides, sulfates, carbonates, and halides with acicular and banded textures representing discharge pulsations.

The Axel Heiberg canopy is one of only three known exposed evaporite canopies. ABSTRACT Axel Heiberg Island (northern Nunavut) contains the thickest Mesozoic section in Sverdrup Basin. Anhydrite, an important rock-forming mineral, anhydrous calcium sulfate (CaSO 4).It differs chemically from gypsum (to which it alters in humid conditions) by having no water of crystallization.
Anhydrite occurs most often with salt deposits in association with gypsum, as in the cap rock of the Texas-Louisiana salt domes. Anhydrite is one of the major minerals in evaporite deposits; it also is. it is and island in the qikiqtaluk region.

Sometimes the shell of anhydrite can be composed of strontium, depending where you find it.Ellesmere Island, which form the northwest border facing the Arctic Sea, reach altitudes of 11, feet. They extend into Axel Heiberg Island and are perhaps continuous with those which cross North Greenland.
