Cambrian
the cambrian was the first period of the Lower Palaeozoic, lasting about 30 million years.
the cambrian was between 544Ma and 510 Ma.
The cambrian 'when life appeared in abundance in the Sea! But not the land'.
Four main continents present in the cambrian period =
1)Gondwana
2)Laurentia
3)Baltica
4)Siberia.
Where was Britian in the cambrian?
in the cambrian britian was seperated, onto two different continents.
Scotland- part of Laurentia (0 )
England and whales- part of Gondwana (60 s)
A huge 4,500km ocean seperated scotland from England and whales! in the cambrian.( and yet today they are in fact together)
- The iapetus ocean seperated them in the cambrian.
-The iapetus ocean was a spreading ocean in the cambrian( may have once been 7000km wide).Proof =paleomagnetism of new basalt found today as tayvallich basalts. Alwell as the lack of andesitic rock which would suggest subduction and therfore closing.
