See WP:LEAD. The present lead is not a summary of the main content - it could be seen as a summary of content that is waiting to be written in more depth, that lacks a summary of the actual "content" section (Geology). Either the lead should be converted to a section and a new very brief smmary written, or the sections corresponding to the lead should be added (and a summary of the Geology section added to the lead).
