Canadian Amber, when undisturbed lies along bedding planes
in coal or carbonaceous sediments. The thinner strata of low-grade coal and
lignite seem to bear more amber then the thicker, higher grade coal layers.
Canadian Amber tends however to be found in secondary positions, sometimes being
concentrated on the surface of the ground at, or immediately downslope from coal
outcrops, (Langenheim et al. 1960)
