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 ís 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.
BAKED MARGIN
Abba Intrusion!!!
Dalradian Super Group-per,
Itís a meta-sediment,
Looks like it's a schist,
Why do we care about this?
Because weíre all geologists.
BAKED MARGIN
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.
So my my this geology guys ...
 ... Geology's like travelling in time
There were some rocks from the Jurassic and
Cretaceous
But they were quite boring, and not that siliceous,
& 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!
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
