Duplicate pages problem

The Moz report shows that I have 600 Duplicate pages, How can I locate the problem and how can I fix it?

How large is your site?

do a site: search for your site, if you are unaware of duplicate content it could be URLs with parameters appended getting indexed or https pages getting indexed.

1500 pages.

So what can I do about that?

Are you referring to duplicate page content? if so this could be down to the design template of your site. i.e same header, sidebar, footer on each page e.c.t .if so I would not worry to much about it as long as the main content is different on each page, I f you are referring to pages that are identical this can be produced by php software creating duplicate pages i.e  /page1 could also be /something else, If so you could identify the structure of the url and instruct your sitemap generator program to ignore the undesirable url, or webmaster tools has a section for this also i believe.
