Feldspathic Sandstone Flagstone from Near Hudson Hope, Northern British Columbia - Potential for Sandstone Production in British Columbia
There are a number of well-established flagstone and dimension stone producers supplying the existing market in Western Canada and adjacent US states. Such products are distributed in pallets of approximately 1 cubic metre (around 2 metric tonnes) (Photos 1, 2 ), sorted by thickness and degree of processing, such as with or without sharp edges, random or square shapes, etc. The BC and Alberta products are complemented by imported stone types not available from local producers.
Geologic appraisal of dimension-stone deposits
From abstract: The construction stone industry comprises two major branches-dimension stone and crushed and broken stone. For purposes of geologic appraisal, deposits of these two categories should be treated separately, because they differ widely in use, mode of development, and exploitation. Deposits of dimension stones are subjected to much greater selectivity with respect to physical properties, uniformity, and modes of occurrence; these demand a much more critical and 
detailed study of geologic and mineralogic features.
On the use of the Hardening Soil Small Strain model in geotechnical practice
This article highlights the importance of using advanced constitutive soil models in numerical modelling as daily geotechnical practice. In this context, the Hardening Soil (HS) model is presented as the most advanced soil model implemented in the ZSoil finite element code. The article recalls the basic features of the HS model and it explains their role in numerical simulations. The role of pre-failure non-linear behaviour of soils is also discussed. An application of the HS model is illustrated on typical geotechnical problems such as retaining wall excavation, tunnel excavation and undrained loading followed by consolidation.
