Der volle Inhalt der QuelleChemical weathering of silicate minerals is central to numerous environmental and societal challenges. This study addresses the long-standing question of the inconsistency between field and laboratory estimates of dissolution kinetics, by revisiting current approaches of mineral reactivity. It is demonstrated that evolution of feldspar reaction rates are inaccurately describedby current kinetics rate laws, due to textural and structural changes occurring at the fluid-mineral interface over the course of the dissolution process. A novel method is developed to enable probing biogeochemical weathering rates in the field. Bacterial and fungal metagenomic data reveal that subtle reciprocal relationships are established between microorganisms and mineral substrates within the mineralosphere. This thesis emphasizes the impact of passivation phenomena on dissolution rates, under field-relevant reacting conditions and the incapacity of microorganisms to overcome the passivation barrier

Der volle Inhalt der QuelleStudying the topography of altered rock surfaces represents a cornerstone for reconstructing past environmental conditions and for the identification of traces of life in the geological record, on Earth and beyond. Indeed, the surface microtopography of altered minerals has proven effective in retaining signatures of fluid-mineral interactions. For example, etch pits are among the commonly accepted signatures of interactions between a highly undersaturated aqueous fluid and a mineral surface. However, additional imprints of water-mineral interactions remain to be defined. On a similar note, weathering imprints supposedly left by microorganisms have been proposed as potential biosignatures. These include etching features and microchannels resembling microbes in ‘size, shape and distribution’. Neverthless, it has been shown that qualitatively similar surface features can also be reproduced through purely abiotic processes. Therefore, it becomes crucial to develop less ambiguous criteria to differentiate between abiotic and biotic weathering features. In this PhD thesis, these questions were addressed through a combination of experimental and modeling approaches. Calcite dissolution experiments were carried out at various saturation states, both under abiotic conditions and with a cyanobacteria biofilm covering the calcite surface. Time-resolved statistical analyses of the resulting surface topography acquired using vertical scanning interferometry were then conducted. The results suggested that the steady-state surface roughness resulting from dissolution can be used as a proxy to back-estimate the saturation state of the fluid. In this context, stochastic modeling of crystal dissolution helped defining the relaxation time that is required for the surface microtopography to switch from a given steady-state configuration to another, as a result of a change in the solution composition. This suggested that the microtopography of naturally weathered minerals may be representative of the fluid composition most recently visited. Furthermore, the experimental results showed that statistical characterizations of the surface microtopography of altered minerals can be used to quantitatively -thus less ambiguously- detect bio-weathering imprints. Specifically, at far-from-equilibrium conditions, biofilm-mediated dissolution led to the formation of high-elevation regions across the calcite surface, which could be quantitatively detected by semi-variogram analyses. Atomic-scale stochastic simulations of the dissolution process suggested that these bio-weathering features resulted from a local increase in fluid saturation state at the biofilm-mineral contact, leading to a localized reduction in dissolution rate. Altogether, this work provides novel, mechanistically-supported quantitative criteria that may help reconstruct past weathering conditions and identify mineral bio-weathering signatures in natural settings in a non-destructive and less ambiguous way
