Questions to be addressed

Ideas for questions to be addressed - please add to this!

 What were the main tectonic mechanisms in the ancient Earth and other planetary bodies?

• Hadean tectonics

• Archaean tectonics: evidence for and against plate tectonics (from geology, geochemistry, geophysics...)

Past and present tectonic processes on Venus & mars

•  Is Venus a likely analogue for the Archaean Earth?

• Mars tectonics

Implications of different tectonic models for the origins of life on Earth and other rocky planets?

Why is knowing whether or not plate tectonics  existed in the Archaean important?

• Different metallogenic models, especially for critical and strategic minerals

• Different settings for natural hydrogen: ophiolites are one of the main H2 sources, as may be ancient SCLM rifts or regions of mantle dripping (evidence of pathways from MT) 

• Different chemistry of ancient oceans and atmosphere; important for understanding origins of life?

What extra information is required / future collaborative research directions?
