The rock looks like granite with a green mineral band in it. I found it today in a old dry creek bed about 2 miles from the mountains. I was out four wheeling in the bed and also looking for rocks and this one stood out like a sore thumb so I stopped and picked it up. The granite part scratches with a stainless steel pocket knife, the green part seem too not scratch. The granite parts scratches easily with quartz, the green part I have to really press down to get it to scratch. The green band is a dull olive green color and opaque. I am wondering if anybody knows what mineral the green band is.

Looks like Epidote to me also but hard to tell from just a photo.
