Where can I find the code for the default blog view?

Hi,
Sorry for the stupid sounding question, but I’m really stuck. in my quest of porting a rather large existing site to enfold I encountered a problem:
My existing site’s content is separated in various categories, each with it’s own category-{slug}.php. I want to keep it that way and I also like the look of enfold’s default blog-Style. (The one that is set with “And where do you want to display the Blog?”)

I want to create a number of those category-{slug}.php files and edit each one of them to my needs, but I cannot find the code for the blog view.
So my question is this: where can I find the code for that so I may use it in a category-{slug}.php file?

Thanks,
