This is a song about the Geology of Arran, which is geologically accurate (mostly...) and could hopefully help with revision! Imagine it being sung to the tune of 'American Pie' by Don McLean (though it was influenced by the 'The Saga Begins' version by Weird Al Yankovic) and the 'Abba Intrusion' to the tune of 'Super Trouper'. Also, a lot of the rhymes are tenuous at best, so use your imagination to make it work! Geologise!!!
Geology of Arran Song
A long, long time ago,
About 400 million years or so,
Back in the Ordovician,
The Iapetus Ocean began to close,
Continents collided and the seafloors rose,
Right up to the start of the Silurian.
We saw some rocks from the Bouma series,
Which was consistent with our theories,
That these formed on the continental slope,
Down which dense sediment did elope.
And when England collided with an island arc,
Volcanic eruptions occurred, with mafic minerals dark,
Their bulbous glassy margins have made their mark,
On the Ayrshire coast.
So my, my this here ophiolite,
Brought the sea floor to the surface and out into the light,
Check those pillow lavas and those coarse turbidites,
The geology on the coast is alright,
The geology on the coast is alright.
But then we went to Arran; there were so many rocks,
From all the different eras and most of the epochs,
And a few unconformities were seen.
There were cross-bedded, red, well-sorted sands
From the hot, arid deserts of the Permian;
Water table rises were inferred by honeycomb weathering.
We saw cyclothems from the Carboniferous.
It looked like these rocks had been put here for us.
There were deltas; lime and siltstones,
And even some fossils of bryozoans.
Then we saw something quite bizarre;
A coarse conglomerate or a breccia;
Flash floods had created a massive lahar,
Right next to the Devonian Old Red.
So my, my this geology guys.
We thought Arran was so barren, but now that's just a lie.
Put our hard hats on and kissed our clean boots goodbye,
Singing geology's like travelling in time,
Geology's like travelling in time.
Dalradian Super Group-per,
It's a meta-sediment,
Looks like it's a schist,
Why do we care about this?
Because we're all geologists.
These rocks dated back to the Pre-Cambrian,
And whoa -- the schist has hit the alluvial fan;
The turbidite sequence got metamorphosed.
We mapped out the valley of North Glen Sannox,
By identifying rock types at lots of outcrops,
To check the lithology that had been proposed.
If there's Triassic beds with footprints of dinos,
Then work out the dip with your compass-clinos.
It's all intruded by dykes,
And if you work out their strikes,
They lead to a sill made from Quartz-Feldspar Porphyry,
Which all upwelled during the Tertiary;
The pluton in the middle looks quite like G5A,
All caused by a hot spot.
There were some rocks from the Jurassic and Cretaceous,
But they were quite boring, and not that siliceous,
And some glacial erratics from the Quaternary.
The conjugated kink bands and folded beds
Made it much clearer in our heads
About the wide-scale orogeny.
And by the sill of Drumadoon,
We swear that we will come back soon,
When our knowledge of rocks is greater,
Like that of our amazing demonstrators.
Our highlights include Hutton's Unconformity,
And also the meal enhanced by BP.
From this week it's plain to see:
We all love Geology!
