The presence and the stability of organics and metalorganics at geological phases are a vast source of information on the potential for extraterrestrial versus terrestrial sources of essential ingredients for the genesis of prebiotic chemistries. Carbon-based molecules in meteorites can survive harsh extraterrestrial conditions within the asteroid parent body´s history, during atmospheric entry to the Earth’s surface and during their residency on a highly energetic early Earth´s surface. The survival of specific organic matter when exposed to electrical, thermal and shock stresses, must have played a major role in the early prebiotic chemistry and the emergence of life on Earth. This project focuses on the stability of metalorganics in experimental conditions mimicking such systems.

有机质和金属有机物在地质阶段的存在和稳定性是一个巨大的信息来源，表明地外来源与陆地来源之间可能是益生菌化学形成的基本成分。陨石中的碳基分子可以在小行星母体S的历史中、进入大气层进入地球表面以及停留在早期能量极高的地球S表面期间，在恶劣的地外条件下生存下来。当特定的有机物暴露在电、热和冲击压力下时，它们的存活肯定在早期的益生化学和地球上生命的出现中发挥了重要作用。这个项目的重点是金属有机物在模拟这类体系的实验条件下的稳定性。
