Formation
Burckle Crater has not yet been dated by radiometric analysis of its sediments. The Holocene Impact Working Group think that it was created about 5,000 years ago (c. 2800–3000 BC) during the Holocene epoch when a comet impacted the ocean, and that enormous megatsunamis created the dune formations which later allowed the crater to be pin-pointed.
Unusual calcite (CaCO3) crystals, translucent carbon spherules, fragments of basaltic glass and native metals (native iron and nickel) are reported near the crater and associated with impact ejecta or hot water precipitates. Seawater at the depth of the crater is undersaturated with respect to calcite and rapid burial would be required for the preservation of those crystals.

Famous quotes containing the word formation:
“... the mass migrations now habitual in our nation are disastrous to the family and to the formation of individual character. It is impossible to create a stable society if something like a third of our people are constantly moving about. We cannot grow fine human beings, any more than we can grow fine trees, if they are constantly torn up by the roots and transplanted ...”

—Ralph Waldo Emerson (1803–1882)
“Those who were skillful in Anatomy among the Ancients, concluded from the outward and inward Make of an Human Body, that it was the Work of a Being transcendently Wise and Powerful. As the World grew more enlightened in this Art, their Discoveries gave them fresh Opportunities of admiring the Conduct of Providence in the Formation of an Human Body.”
—Joseph Addison (1672–1719)
