Meanings of amygdaloidal in английском

The structure in one of these specimens approaches to the amygdaloidal.

Here and there masses of highly cellular and amygdaloidal lavas protrude.

The lower (Ashangi group) consists of basalts and dolerites often amygdaloidal.

Some specimens of variegated pebbles and jasper were found here embedded in the amygdaloidal rock.

These ranges and isolated hills are all of the same sandstone formation, and capped with basalt, more or less amygdaloidal.

Solid basalt with minor variations, though I wouldn't rule out the possibility of encountering some large amygdaloidal pockets here and there.

In some of the fragments on Mount Napier these cells or pores were several inches in diameter and, unlike amygdaloidal rocks, all were quite empty.

Amygdaloidal cells, half filled.
