Karst environments are characterized by distinctive landforms related to dissolution and a
dominant subsurface drainage. The direct connection between the surface and the …

Quartz is considered one of the less soluble minerals of the Earth's crust, and thus hardly
affected by chemical weathering. Despite this, for more than forty years, it is clear that the …

Karst aquifers contribute substantially to freshwater supplies in many regions of the world,
but are vulnerable to contamination and difficult to manage because of their unique …

This paper presents geomorphic evidence for the significant role of surface-subsurface
connectivity in the geomorphological evolution of tabular hills (mesas) capped by …

The permeability of bedrock aquifers varies by more than four orders of magnitude between
different lithologies, but the reasons for this large range remain unexplained. In this review …

Since human beings started to colonise the world, slowly migrating (in multiple directions)
from the African Rift and ultimately reaching the southernmost territories of the Americas …

The aim of this work is to provide a synthetic outline of some of the processes of transient
nature occurring in caves, focusing on poorly studied general aspects of underground …

Although the general concept that escarpments in layered rocks retreat through time was
offered more than 150 years ago, recognizing the exact mechanisms, patterns and rates of …

The majority of caves are formed within limestone rock and hence our understanding of cave
microbiology comes from carbonate-buffered systems. In this paper, we describe the …

Spectacular rock-cut landscapes consisting of closely spaced residual rock blocks
separated by narrow intersecting corridors are variously termed as 'rock cities' and 'ruiniform …
