So what DO we know about columnar joints? Well, the rapid subaerial cooling means the lava flow will cool from the top down, cracks forming as a response to tensile stresses within the cooling body. Specifically, the lava is contracting as it cools to a solid, therefore something has to give.
Basalt is a common volcanic rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of our planet. Jointed basalt columns, as the most famous and most beautiful basalt formations, exists on many places on earth. These unusual columns are predominantly hexagonal in crosssection, but basalt polygons with three to twelve or more sides can be observed.
Olympus mons, a shield volcano on Mars, was formed from basaltic lava flows. It is the largest known volcano in the solar system and the highest mountain on Mars. Three rockforming environments is responsible for most of the basalt formed on Earth: oceanic divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents.

The thickness of a basalt lava, particularly on a low slope, may be much greater than the thickness of the moving lava flow at any one time, because basalt lavas may "inflate" by supply of lava beneath a solidified crust. Most basalt lavas are of ʻAʻā or pāhoehoe types, rather than block lavas.
Basalt rock is one of the most abundant components in the Earth''s crust, and is commonly formed due to lava flow. In this article, we will take a look at the properties of this igneous rock, and the various ways in which it is useful to us.
Basalt Fiber • Basaltic magma is commonly produced by direct melting of the Earth''s mantle, the region of the Earth below the outer crust. On continents, the mantle begins at depths of 30 to 50 km. • Shield volcanoes, such as those that make up the islands of Hawaii, are composed almost entirely of basalt. 1 • Huge outpourings of lava called "flood basalts" are found on many continents.
The Tseax Cone was the source for a major lava flow eruption between 1668 and 1714 that travelled into the Tseax River, damming it and forming Lava flow subsequently travelled 11 km (7 mi) north to the Nass River, where it filled the flat valley floor for an additional 10 km (6 mi), making the entire lava flow approximately km (14 mi) long.
Basalt is an igneous, mafic, and volcanic rock which is produced by lava flows in many different volcano types. It contains mainly volcanic glass, pyroxene and plagioclase feldspar and is finegrained. Basalt is one of the most common types of rock on Earth as well as other planetary bodies in the ...
The third basaltforming environment is a continental environment where a mantle plume or hotspot delivers enormous amounts of basaltic lava through the continental crust and up to Earth''s surface. These eruptions can be from either vents or fissures. They have produced the largest basalt flows on .
