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 …

Originally published in 1989, Karst Geomorphology and Hydrology became the leading
textbook on karst studies. This new textbook has been substantially revised and updated …

The first integrative systematic revision of the relictual Asian scorpion family
Pseudochactidae Gromov, 1998, making use of an unprecedented collection of material …

Sandstones form the backdrop to some of the world's most spectacular scenery, and are
found all over the planet and in all climates. Following on from the authors' successful 1992 …

The paper reports the results of SiO2 analyses in the Aonda Cave system, located on the
Auyán-tepui, one of the widest table-mountains of the Gran Sabana (South Venezuela) …

A detailed petrographic, structural and morphometric investigation of different types of caves
carved in the quartz–sandstones of the “tepui” table mountains in Venezuela has allowed …

Venezuelan table mountains (tepuis) host the largest arenite caves in the world. The most
frequently used explanation of their origin so far was the “arenization” theory, involving …

In situ measurements of discharge, pH, electric conductivity (EC), temperature, and SiO 2
content have been carried out during five expeditions in the last 20 years on the summit …

Chert and other hard monomineralic quartz grains weather mostly by mechanical processes
in modern environments. Their clasts are overrepresented in conglomerates and sands …

A hybrid numerical, finite differences and semi-analytical/empirical model has been
developed to evaluate the spatial and time scale of chemical weathering along a fracture in …
