The building stones and slates of Killin : an investigation of stone for the built heritage [PDF]

, 2010
The village of Killin lies in an area of dramatic landscape and mountain scenery. The use of local stone in the buildings gives a direct connection to this landscape and reflects the local geology, comprising mostly metamorphic rocks of Precambrian age

Imaging compaction band propagation in Diemelstadt sandstone using acoustic emission locations [PDF]

, 2008
We report results from a conventional triaxial test performed on a specimen of Diemelstadt sandstone under an effective confining pressure of 110 MPa; a value sufficient to induce compaction bands.

Stratigraphy of Tithonian (Ohauan-Puaroan ) marine beds near Port Waikato, New Zealand, and a redescription of Belemnopsis aucklandica (Hochstetter). [PDF]

, 2001
Some 1500 m of marine Ohauan and Puaroan strata in the Port Waikato region of New Zealand are restudied in an attempt to resolve lithostratigraphic and biostratigraphic anomalies in published works.

Experimental study on the damage characteristics of cyclic disturbance and acoustic emission characteristics of different types of sandstones under high stress in deep mines

Deep Underground Science and Engineering
Three sandstone specimens common in rock engineering were selected to study the differences in the mechanical properties of rocks with different lithologies. The development and expansion of the internal cracks in the specimens were observed by combining
