The mountain chain disappears – and the dinosaurs arrive!
The Caledonian mountain chain is an example of how plate movements and continental drift can cause collisions and the upheaval of huge mountain chains. After the horizontal compressional forces ceased, the forces of gravity, wind and water took over and started the process of eroding away the mountain chain. But, nearer to our time the land rose up again to a plateau landscape in the east which slanted down toward the ocean in the west!
The pioneers who discovered the natural history of Hordaland
When Professor Emeritus Knut Fægri (1909-2001) was asked to write the book's chapter about the natural science pioneers of Hordaland, he answered unequivocally, "yes". It was one of the last things he wrote before he died, at the age of 92. In typical Fægri language he presents some of the scholars who, in the time before the University of Bergen was founded, led the way in studying the natural science of The West Country.
The Precambrian Era and Precambrian basement rocks
Almost nothing is as solid, unchangeable and stable as the Norwegian Precambrian basement rocks. Here, there are no volcanic eruptions or violent earthquakes that can cause natural catastrophes. But, it has not always been that way! There have been periods when glowing hot lava flowed over it or when large parts of the Precambrian basement have "taken a beating", both in Precambrian times and during the Caledonian mountain-building event.
The West Country
Hordaland er en scene for naturens mange vekslinger – i topografi, berggrunn, vegetasjon og dyreliv, gjennom klimaperioder og årstider.
