<p>The text suggests "igneous intrusions into sandstone" and
"sandstone eroded away to expose the igneous intrusions". <br>
</p>
<p>I'm familiar with igneous "plugs" such as my nearby Black Mesa
and the famous Devils Tower in WY. I believe the characteristic
"basaltic piles" I see in other formations in my area imply
'igneous intrusion" rather than "igneous flow" reflecting the way
such things cool.</p>
<p>The Spanish peaks dikes are radial from the peaks reminiscent of
a "Mordor-like landscape" with cracks radiating from the mountain
and lava rising up out of it.</p>
<p>Thanks to the other curious-obsessives here to help push me from
decades of "wondering" to feeling at least a little more informed
about the geology (and weather).</p>
