cosmogenic
- Adjective:
- Relating to the origin and development of the universe: Specifically pertaining to the branch of astronomy or astrophysics that studies the beginning, structure, and evolution of the cosmos.
- Concerning cosmic-ray-induced nuclear reactions: In physics and geology, describing nuclides or processes produced by the interaction of cosmic rays with matter, such as in the Earth's atmosphere or on its surface.
- Adjective:
- The scientist presented a cosmogenic theory about the formation of the first galaxies.
- Researchers measured cosmogenic isotopes in the rock to determine how long it had been exposed at the surface.
"cosmogenic nuclide": A specific type of atom (isotope) produced when cosmic rays interact with other atoms. These are used as "clocks" in geology and archaeology.
- The concentration of beryllium-10, a cosmogenic nuclide, helped date the ancient glacial deposit.
"cosmogenic production rate": The rate at which cosmogenic isotopes are formed in a material, which depends on factors like altitude and latitude.
- Calculating the cosmogenic production rate is crucial for accurate surface exposure dating.
Cosmogonic (adj): Often used interchangeably with "cosmogenic," especially when referring to theories about the universe's origin.
- The cosmogonic models of the early 20th century have been refined by modern observations.
Cosmology (n): The scientific study of the large-scale properties and history of the universe as a whole.
- Cosmology seeks to understand the cosmogenic processes that shaped everything we see.
Cosmological (adj): Pertaining to cosmology.
- The cosmological principle is a fundamental assumption in modern cosmogenic theories.
- Cosmogonic: Relating to the origin of the universe or solar system.
- Cosmological: Concerning the origin, structure, and space-time relationships of the universe.
Cosmic ray exposure: A context where cosmogenic effects are studied.
- The meteorite's history was unraveled by analyzing its cosmic ray exposure and cosmogenic isotopes.
Surface exposure dating: A geological dating technique that utilizes the buildup of cosmogenic nuclides.
- Surface exposure dating relies on precise measurements of cosmogenic isotopes like chlorine-36.
