The engineered barriers of a repository (waste form, container, clay buffer and backfill material and repository stmcmre) which will degrade with time due to various physico-chemical processes, strongly affect the geochemistry of fluids and rocks of the near field environment (redox properties, sorption properties, solubility limits, equilibrium chemistry, etc.) and determine the speciation and the subsequent migration behaviour of the radionuclides into the far field.

Four billion years ago the seeds of life had been firmly planted. The Archean Earth boasted substantial repositories of serviceable organic molecules, which became locally concentrated and assembled into vesicles and polymers of biological interest. Once the first molecular replicator emerged, molecular natural selection took off. In such a world, nascent biology and ancient geochemistry became inextricably entwined. For example, Earth s surface mineralogy diversified as a result of varied microbial influences, which altered ocean and atmospheric chemistries at scales from local to global (2).
