Definition

Chemical weathering may be defined as the spontaneous and irreversible thermodynamic process that causes degradation of the mineral phases under the prevailing environmental conditions at the surface of the Earth. If one must differentiate the weathering in the continental and marine environments, chemical weathering is usually considered to be the solid/solution interactive process occurring in contact with the atmosphere. By extension, in the language of the specialists of the critical zone, chemical weathering may be defined as that set of processes which alter a rock into a layer of chemically and physically transformed superficial material (i.e., regolith) which is susceptible to evolve (soil or karst) with time following biogeochemical processes.

Introduction

While this process of chemical modification can be easily formalized by writing on paper, for example, the chemical reaction of dissolving a mineral (1), the reality is much more complex because it actually...
