lentils
Lens (geology) - Wikipediaen.wikipedia.org
In geology, a lens or lentil is a body of ore or rock that is thick in the middle and thin at the edges, resembling a convex lens in cross-section.
Thus in Lone Tree Canyon there is well exposed a section of quartz mica schists, in which such unequivocal sedimentary features as crossbedding and quartzitic sandstone lentils are preserved.
They consist of dark grey clay schist as well as sandstone lentils up to 5 cm thick.
