Hopefully someone will be able to help me here

we found these rocks in our garden when we were tilling up the dirt.. I am guessing they are pegmatites?? i live in middle GA if that helps... I'm wondering what all it's made of?? there looks like a bunch of stuff in there, lol... anything worth "harvesting"?? any help would be greatly appreciated?? Oh yeah, these are pics of the rocks dry.. I can take some with the rocks wet if i need to.. <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977727"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977728"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977729"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977730"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977731"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977732"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977733"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977734"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977735"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977736"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977737"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977739"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977740"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977741"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977742"/><img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=977743"/>
