Blocks of Proterozoic granitoid
rock (granite and gneiss of the Grenville Province)
from a Quaternary granular deposit located south
of Sainte-Brigitte-de-Laval. The material is screened,
but not crushed, to produce five categories of
natural stone based on particle diameter*. It
is used as decorative stone and landscaping stone
(low walls). The stone is also used for protecting
riverbanks and bridge embankments.
*Given that the diameter of gravel varies from
0.5 to 20 cm, that a pebble's varies from 20 to
60 cm and that a block's is greater than 60 cm.
