Abstract
Laser-Raman imagery is a sensitive, noninvasive, and nondestructive technique that can be used to correlate directly chemical composition with optically discernable morphology in ancient carbonaceous fossils. By affording means to investigate the molecular makeup of specimens ranging from megascopic to microscopic, it holds promise for providing insight into aspects of organic metamorphism and biochemical evolution, and for clarifying the nature of ancient minute fossil-like objects of putative but uncertain biogenicity.
摘要
激光拉曼成像技术是一种灵敏、无创且无损的技术，可用于直接关联古代碳质化石中化学成分与光学可分辨的形态。通过提供从宏观到微观研究标本分子组成的手段，它有望深入了解有机变质作用和生物化学演化的各个方面，并阐明具有假定但不确定生物成因的古代微小化石状物体的性质。
