In general, the geological event that might take place is an earthquake or mountain ranges may form.
Ano pa po?
Those are the only two that might happen, since continental plates are thick, when they collide, enormous earthquakes happen and no magma can penetrate it (meaning no volcanoes can form) so only earthquakes and mountain ranges may form. In this case, the Himalaya Mountains is the best example of what forms when two convergent continental plates collide.
