Today, HALIP covers an area greater than 1,000,000 km (390,000 sq mi), making it one of the largest and most intense magmatic complexes on the planet. However, eroded volcanic sediments in sedimentary strata in Svalbard and Franz Josef Land suggest that an extremely large portion of HALIP volcanics have already been eroded away. 965: 370:
is closely associated with the Svalbard province. Franz Josef Land is located approximately 300 km (190 mi) east of Svalbard and contains igneous rocks of very similar composition to those of Svalbard. However, the archipelago is scattered with a prominent swarm of southeast trending dikes.

that seems to suggest the presence of a mantle plume beneath the Alpha Ridge. This province contains igneous rocks of both tholeiitic and alkaline composition. There are also a respectable number of sills and flood basalts in the province. The flood basalts in the Canadian Arctic Islands are similar

The northern Greenland province, also known as Peary Land, contains three dike swarms. The Nansen Land swarm trends SSE-SE and is the oldest of the swarms. The middle-aged swarm is known as the Erlandsen Swarm and trends SE-ESE. The J. P. Koch Swarm is the youngest of the three and trends eastward.

The Amerasian Basin's most prominent feature is the Alpha Ridge – which is thought to be the location of the mantle plume that fed the HALIP. The ridge reaches a height of 2,700 m (8,900 ft) from the seafloor. Also in the region are a few basaltic dikes. The Amerasian Basin extends over

Extensive sills and volcanic flows can also be found in the region, as well as a few dikes of other trends. The timing of the Franz Josef Land formations and the Svalbard formations is thought to be nearly identical, furthering the evidence for a large initial plume head model for the HALIP.

largely appear in the form of sills that can reach thicknesses of 100 m (330 ft) and continuously extend for up to 30 km (19 mi) laterally. The basaltic rocks found in Svalbard have an intra-plate composition and are thought to originate from a source near the

The Barents Sea province is characterized by igneous intrusions with much similarity to Svalbard and Franz-Josef Land. This region is well known for being petroleum-rich. The Barents Sea province covers an area of 15,000 to 20,000 km (5,800 to 7,700 sq mi).

The HALIP event lasted from 130 million years ago to approximately 60 million years ago. During its active period, there were two distinct phases of volcanism. The first phase lasted from 130 million years ago to 80 million years ago and was characterized by

The two younger swarms tend to have igneous rocks of alkaline composition, while the Nansen Land swarm tends to have more tholeiitic composition. The Peary Land province covers an area of over 80,000 km (31,000 sq mi).

The second phase lasted from approximately 85 million years ago to 60 million years ago and was characterized by mildly alkaline igneous activity and the eruption of flood basalts. The 470:, a crocodile-like reptile, found in the Canadian Arctic suggests that polar climate was much warmer during the Cretaceous when average annual temperature must have exceeded 14 Â°C. 661: 755:"Geochemical systematics of High Arctic Large Igneous Province continental tholeiites from Canada – Evidence for progressive crustal contamination in the plumbing system" 1569: 1341:"Dolerites of Svalbard, north-west Barents Sea Shelf: age, tectonic setting and significance for geotectonic interpretation of the High-Arctic Large Igneous Province" 803:
