Conspicuous Neogene tectonic forms, faultline valleys, fault-angle valleys, etc. were discovered in the SE marginal part of the Třebíč Massif. Relations between the Tertiary and older tectonics were studied. The regularity of special distribution

This study focuses on the southern branch of the South Armorican Shear Zone, well identified in the Vendée area. Syntectonic intrusions, related to different shear zones, are used to define the regional deformation characteristics at the time

Effect of rock hardness and moisture content on tafoni weathering in the granite of Mount Doeg-Sung, Korea
Relationships are investigated between growth processes of granite tafoni and rock properties such as rock hardness and moisture content. Field evidence shows that the rock surface of the inner backwalls and ceiling of tafoni have reduced hardness
and higher moisture content compared to the outer visor of tafoni and to vertical cliff walls with no tafoni. This suggests that tafoni arise in weathered rock where conditions of low strength and high moisture content are both satisfied.

A new technique for non-destructive field measurement of rock-surface strength : an application of the Equotip hardness tester to weathering studies
of the sandstone blocks using both an Equotip hardness tester and an L-type Schmidt hammer. This article first describes the results, and secondly evaluates the usefulness of the device in quantifying the degree of rock weathering.
Tafone-like depressions have developed on the Aoshima sandstone blocks used for a masonry bridge pier in the coastal spray zone. To evaluate quantitatively the strength of the thin weathered layer, the hardness was measured at the surface
