Theories On Origin
The origin of carbonado is controversial. Some proposed hypotheses are as follows:
- Direct conversion of organic carbon under high-pressure conditions in the Earth's interior, the most common hypothesis for diamond formation
- Shock metamorphism induced by meteoritic impact at the Earth's surface
- Radiation-induced diamond formation by spontaneous fission of uranium and thorium
- Formation inside an earlier-generation giant star in our area, that would have long ago exploded in a supernova.
- An origin in interstellar space, due to the impact of an asteroid, rather than being thrown from within an exploding star.
None of these hypotheses for carbonado formation had come into wide acceptance in the scientific literature by 2008.

Famous quotes containing the words theories and/or origin:
“Generalisation is necessary to the advancement of knowledge; but particularly is indispensable to the creations of the imagination. In proportion as men know more and think more they look less at individuals and more at classes. They therefore make better theories and worse poems.”
—Thomas Babington Macaulay (1800–1859)
“There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx’s Capital.”
—W.E.B. (William Edward Burghardt)
