Talk:Gondwana
From Academic Kids
According to my lecturer Jørgen Klein (2004) the breakup of Gondwana is as follows: 130 Ma India breakes loose. 80 Ma Africa and South America drift apart, and Australia and antarctica some later. About 30 Ma Africa connects with Eurasia.
According to the animation on the link I've inserted the breakup is like this:
160-150 Ma: the southern part of Gondwanaland starts drifting away from South America and Africa.
120 Ma: India is disconnected, Africa starts disconnecting.
100 Ma: Africa and South America disconnect, Australia and Antartica disconnect.
90 Ma: India and Madagascar disconnect.
All this conflicts with 20-60 Ma, so I'm not sure what to trust, don't have time for more research now, but maybe later. Dittaeva 12:07, 4 Feb 2004 (UTC)
Dating of geologic events is kind of variable, because dates are given + or - so many years and such. Methods are not exact; with millions of years, people usually just aim for the ball park. They should all roughly follow though. I'll look at this; I've been editing geology articles and dating is an aspect I haven't paid a lot of attention to. I start looking for inconsistencies. If you think your dates are better, by all means put 'em in. --DanielCD 22:26, 2 Dec 2004 (UTC)
