RAMAN-GEOTHERMOMETER FOR CARBONACEOUS CHONDRITES

Доклады Российской академии наук. Физика, технические науки, 2023
Samples of the Murchison meteorite (carbonaceous chondrite, type CM2) were kept isothermally in a specially designed device at temperatures of 200, 500 and 800°C. After the samples cooled down in an inert helium atmosphere, Raman scattering spectra were taken.

Amino acids in carbonaceous chondrites

Origins of Life, 1974
For almost 20 years laboratory experiments have advanced the concepts of chemical evolution, particularly with regard to formation of the amino acids. What has been generally lacking is concrete natural evidence for this chemical evolution hypothesis.
