The paleomagnetic angle of _____, also known as magnetic dip, is measured between the Earth's surface and a line of magnetic force directed toward a magnetic pole. Inclination A line from a given location to the magnetic pole will be offset from a line to the respective geographic pole by . Undeformed and unmetamorphosed diabase dykes up to 5 m wide occur in an area of ∼ km 2 about 50 km northwest of Montreal near the village of Sainte-Sophie. The dykes are subvertical and oriented east–west. The most common phenocryst phase is plagioclase (1–2 mm, exceptionally 10 mm), followed by olivine, and in one dyke, : Michael D.

Quebec's Manicouagan Crater is one of the largest fairly well-preserved impact craters on Earth. A ring-shaped hydroelectric reservoir lake 70 km in diameter occupies the centre of the crater.

The reported paleomagnetic study was carried out on 53 oriented samples ( specimens) at 10 sites in the eastern Gaspé Peninsula. All sampled geological units are composed of sub vertical diabase dykes that cut the sedimentary formations of late Early Devonian – early Middle Devonian by: 5. COVID Resources.

This magnetostratigraphic age is consistent with the radiometric age of the Manicouagan impact that formed the second largest known crater in the Phanerozoic at Quebec, Canada.

The results of this study, as well as previous studies, suggest that the chert section, which includes the ejecta layer, was deposited within a paleolatitude range of Paleomagnetic Results.

These results are interpreted to show that the ejecta layer in the Sakahogi section was the product of a large meteoritic impact event that formed the km-wide Manicouagan by: 6.

It is 65 kilometers (40 miles) in diameter, but it is worth remembering that this is small compared with some of the larger lunar structures that measure more than km ( miles) across.
