Carbonatite lava at Ol Doinyo Lengai volcano, Tanzania. Carbonatite (/ k ɑːr ˈ b ɒ n ə ˌ t aɪ t /) is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50% carbonate minerals. [1]
Limestone is the most common carbonate rock [3] and is a sedimentary rock made of calcium carbonate with two main polymorphs: calcite and aragonite.While the chemical composition of these two minerals is the same, their physical properties differ significantly due to their different crystalline form.
Carbonite (ion), the inorganic anion that forms the conjugate base of dihydroxymethylidene with the chemical formula [CO 2] 2− Carbonite (online backup) , an online backup service Carbonite (Star Wars) , a fictional substance, most notably used to imprison Han Solo in the film The Empire Strikes Back
Carbonite was one of the earliest and most successful coal-mining explosives. [1] It is made from such ingredients as nitroglycerin, wood meal, and some nitrate as that of sodium; also nitrobenzene, sulfur, and diatomaceous earth. Carbonite was invented by Bichel of Schmidt and Bichel. [who?] [2] The term Carbonite can refer to these things:
The carbonite ion is an anion with the chemical formula C O 2− 2. This divalent anion forms by deprotonation of carbonous acid ( C(OH) 2 ). Alkali metal salts of carbonous acid, Li 2 CO 2 ( lithium carbonite), K 2 CO 2 ( potassium carbonite), Rb 2 CO 2 ( rubidium carbonite) and Cs 2 CO 2 ( caesium carbonite), have been observed at 15 K .
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.

Ol Doinyo Lengai is an active volcano in northern Tanzania.It consists of a volcanic cone with two craters, the northern of which has erupted during historical time. Uniquely for volcanoes on Earth, it has erupted natrocarbonatite, [2] an unusually low temperature and highly fluid type o
