Artemisia pipe

Last updated

Artemisia pipe is a diamond bearing diatreme in the Slave craton region of northern Northwest Territories, Canada. [1]

Diamond Allotrope of carbon often used as a gemstone

Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form, but diamond almost never converts to it. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.

Diatreme A volcanic pipe formed by a gaseous explosion

A diatreme, sometimes known as a maar-diatreme volcano, is a volcanic pipe formed by a gaseous explosion. When magma rises up through a crack in the Earth's crust and makes contact with a shallow body of ground water, rapid expansion of heated water vapor and volcanic gases can cause a series of explosions. A relatively shallow crater is left and a rock filled fracture in the Earth's crust. Diatremes breach the Earth's surface and produce a steep inverted cone shape.

Northwest Territories Territory of Canada

The Northwest Territories is a federal territory of Canada. At a land area of approximately 1,144,000 km2 (442,000 sq mi) and a 2011 population of 41,462, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of 2016 is 44,291. Yellowknife became the territorial capital in 1967, following recommendations by the Carrothers Commission.

Toozaza Peak is a tuya in the Stikine Ranges of the Cassiar Mountains in northern British Columbia, Canada, located in the Iverson Creek. Toozaza Peak is the summit of a north-south aligned ridge between the head of Toozaza Creek and the head of the Jennings River, just south of the Jennings' divide with the Little Rancheria River headwaters. The Little Rancheria and Toozaza Creek are part of the Liard, while the Jennings is part of the Yukon River drainage via Teslin Lake, and the peak therefore stands astride the line of the Continental Divide. It is part of the Tuya Volcanic Field, a volcanic field associated with the Stikine Volcanic Belt, part of the Northern Cordilleran Volcanic Province.
