best book on gold deposit geology?

[frankly]

Can anyone recommend a good book?

[Overtheedge]

My favorites are:
"Fists Full of Gold", Chris Ralph
"The Elusive Pocket Gold of South Western Oregon", Tom (T.H.) Bohmker

The next is long out of print but I think a real dandy:
"Ore Deposits", Charles F. Park Jr. and Roy A. Mac Diarmid, W.H. Freeman and Co., 1964
