A Central Igneous Complex

The geology of the Isle of Mull shows her long and turbulent history. Her oldest rocks formed when she was in the southern hemisphere; desert sands formed as she drifted northwards through the tropics; lava poured over her as Europe separated from North America; massive igneous intrusions blasted through to form her Central Igneous Complex; and finally, ice had its wicked way with her, ruining her complexion, but making her wildly attractive to geologists and naturalists alike.

Poor Mull, she’s got a Complex.
Her history is to blame:
Born in southern climates,
She’s drifted, lost her aim.

The signs of Mull’s long journey
Are written in her face:
Desert sands and lavas
A crazy, mixed-up case.

And then, to make things worse,
Volcanoes, earthquakes, ice,
Have left their awful imprints
And Mull has paid the price.

But that’s what makes Mull special
To folk who brave the crossing
In ferries, boats (and coracles?)
On stormy seas a-tossing.

There’s nowhere else quite like her –
Unique, some folk would say.
Her Complex makes her special;
Go visit her one day!
