Hi Jo welcome to the forum.
I have a particular interest in the Geology as well. Amble does not have the high drama of the section to the north towards Cullernose Point, which is recognised as significant on a national, if not international scale, but it does have a few interesting features.
Is your organisation part of Amble Development Trust? I see the loveamble.co.uk domain redirects to loveamble.com which is registered at 6 Dilston Terrace in the whois database.
