- many different trap or basaltic rock containing little cavities occupied completely or in part by nodules or geodes various nutrients esp agates quartz calcite therefore the zeolites once the imbedded minerals tend to be detached or removed by decomposition it's porous like lava
- shaped like an almond
- volcanic rock which rounded cavities created by expanding gas have actually later become filled up with calcium deposits
- multiple trap or basaltic rock, containing small cavities, occupied, completely or perhaps in component, by nodules or geodes of different nutrients, esp. agates, quartz, calcite, as well as the zeolites. Whenever imbedded nutrients are detached or removed by decomposition, it is permeable, like lava.
- Alt. of Amygdaloidal
Like an almond. Almond-shaped. Because the amygdaloid nucleus in the mind, a structure that anatomists believed resembled an almond. Amygdaloid is pronounced in three syllables: amyg da loid. From the Greek amydale (almond) + the Greek eidos (like).
(letter.) Multiple trap or basaltic rock, containing little cavities, occupied, wholly or in part, by nodules or geodes of various minerals, esp. agates, quartz, calcite, together with zeolites. As soon as the imbedded nutrients are detached or eliminated by decomposition, it is permeable, like lava.
