The hydrogeology of crystalline rocks as supporting evidence for tectonic inception in some epigean endokarsts
Abstract:
This paper reviews the considerable advances made in recent years to understand the processes leading to the creation of the triple porosity hydrogeology described for karstic limestones. These have concentrated on the physics and chemistry of slow karst dissolution during the inception phase of conduit evolution in sedimentary limestones prior to 'breakthrough', and then considered the subsequent and more rapid phreatic enlargement into networks with high hydraulic conductivity. However, it is not only soluble rocks that can exhibit significant conductivities. A review of the literature of the hydrogeology of 'crystalline' (i.e. igneous and metamorphic) non-carbonate 'hard rocks' that dates from the late-1980s reveals that such rocks can also act as aquifers, especially near the surface. Their discharges supply natural springs and household wells and boreholes, flood mines, and put at risk the underground containment of hazardous wastes. Fractures are utilised within the crystalline rocks (which have negligible primary porosity, and which are assumed not to develop solutional conduits), so that flow rates can exceed the breakthrough point that, in limestones, would mark the transition from laminar to turbulent flow conditions, and fast dissolution. Similar processes should also apply to metamorphic limestones, and, indeed, to sedimentary limestones, some of which are now known to exhibit open fractures created by seismic or aseismic tectonism. In these cases, the slow chemical inception phase may be bypassed, because some karst passages may develop under phreatic conditions, at high wall-retreat rates, immediately after the inundation of epigean fractures formed tectonically. New models of speleogenetic initiation should therefore recognise both the appropriateness of the (chemical) Inception Horizon Hypothesis for the development of deep, long-range, conduits over long periods of time, as well as the importance of fast speleogenesis initiated by tect***[record truncated]***.
