 Mercury
A basin was defined by Hartmann and Kuiper (1962) as a "large circular depression with distinctive concentric rings and radial lineaments." Others consider any crater larger than 200 kilometers a basin.
The Caloris basin is 1,300 kilometers in diameter, and was probably caused by a projectile larger than 100 kilometers in size.
The shock wave produced by the Caloris impact was reflected and focused to this antipodal point, thus jumbling the crust and breaking it into a series of complex blocks.

Mercury is the Caloris Basin, which resulted from a collision with an asteroid.
The basin, which is more that 1000 kilometers across, is visible as the large circular feature at the bottom of the above photograph.

 Calorie Burner
The food calorie is sometimes capitalized as Calorie to distinguish it from the chemistry calorie; however, this capitalization is rarely observed in practice.
However, in chemistry calories have been deprecated as a scientific unit of measure in favour of joules, and therefore in common modern usage the word "calorie" usually refers to a food calorie.
Caloris was likely created by the impact of an object 100 kilometers or more in diameter; this impact is believed to have penetrated the crust into the planet's mantle.

It is obvious that the ridges criss-crossing Caloris Planitia are at least grossly similar to the mare ridges, raising the obvious question of whether the Mercurian plains are in fact maria and presumably lava flows.
The Orientale Basin (Figure P-4.1) has long been recognized as a younger and better-preserved version of the Imbrium Basin and, by implication, is therefore an immense impact crater.
The discussion of the Caloris Basin has concentrated on similarities between Mercury and the Moon, but it is stressed that Mercury is internally quite different.

The basin was a massive affair, and his complexes were sprawled across it, little concern being given to conservation of room.
He had hoped that the Basin would be allowed to be a peaceful research center, however his sponcers back on Earth had warned him that people might wish to take all he had worked for away.
He would have prefered the canisters to have been sent to the basin where it was safer, but it was currently facing the wrong way and there were far too many domes for a safe landing.

  The basin is thought to have been formed by an impact in the history of Mercury and was then filled by lava flows.
