    Hey guys / Gals...

    I have been doing a ton of research on the Oro Blanco Gold District of (Ruby / Arivaca area) Southern Arizona!!  from gulches to detect, from abandoned mines, to cemeteries, to the geology of the area.  I am a sharp guy, I learn quickly and retain information when its taught to me in the field. The only problem,  is when I read all of this information like:

     

     "The principal formation is a series of more or less metamorphosed arkosic sandstones, quartzites, conglomerates, and shales, with some intercalated volcanic rocks. These beds, which are probably of Cretaceous age, rest upon an irregular surface of altered, coarse-grained, grayish diorite. They have been intruded by dikes of basic to acid composition and subjected to complex faulting. East of Oro Blanco Viejo Canyon, they are overlain by a thick succession of volcanic rocks.

    Mineralization is varied: (1) Irregular and lensing quartz veins with spotty, often oxidized, auriferous and argentiferous base metal sulfides and pyrite in fracture fillings or as partial replacements along faults and at fault intersections. Strong supergene enrichment of gold and silver. Host rocks are altered Cretaceous conglomerate and sandy sediments or Jurassic volcanic tuffs with local disseminated pyrite. Most deposits are limited in entent and in depth; (2) Flat-dipping and shallow zones of quartz veinlets and stringers, locally containing gold and silver values and very minor base metal sulfides, usually associated with strong pyritization. Host rock is strongly fractured, sericitized Jurassic volcanic tuff; (3) Steeply-dipping, tabular and lensing, brecciated shear zones containing fine grained native gold and silver associated with finely crystalline quartz and weak iron and manganese oxides in Jurassic volcanic tuff; (4) Small gold-silver placers in several stream beds, derived from the weathering of the many small lode deposits; (5) Weak occurrence of manganese oxides; and, (6) Weak uranium mineralization in fracture zones in volcanic tuffs."  

    STOP STOP STOP STOP - Please do not answer this -- just an example ^^^^  

    I really have no idea what they are refereeing to, or how I can use this information to benefit me,  I was even reading up on the "Yavapai Pre Cambrian Schist"  yeah,  I now know that is where to look for gold, but What the hell does it look like?!?

     

    My Question FINALLY!!!!!!!!

    Are there any PATIENT geologist out there who would love to share their knowledge with me and my dad out in the field (Please live in Tucson, or somewhere close)  I will buy beer, and food, and loan you a detector to use if you'd like, but I love geology and love the technicalities it has to offer, but its not something I can learn at a computer.

    I would really like to possibly make a new friend, but at the same time, learn about the earth and formation of gold bearing veins.  I've taken an college level Geology course, so I am not 100 percent oblivious to the processes.

    Thank you!!!

    Alex - not in your neck of the desert, but have you checked with local colleges and universities, as well as community colleges to see if any of the instructors might be interested in a little one- on -one time out in the field?   Might even hit up the local BLM office and talk to their mineral person.  Quite often they have a pretty good background, but in today's world who knows with them.  Might also check with the state gologist and see if they have any color plates of what the different stuff looks like.  Just a couple of thoughts off the top of my head.

    That is a great idea!!

    Ironically, my Ex-girlfriends Father is a Geologist, he would've been a great asset to us when her and I were still together, but detecting and gold didn't interest me much. I will do some research and see if the U of A has any Geology Professors who would like to go out and walk the landscape with me.

    Thanks Arthur!!

    Alex, go buy (order) a copy of Fists Full Of Gold by Chris Ralph. It is the best publication for the geology of gold on the market that you can find. Bar none.  TTC

    I am going to order that book today!!  If you really think its the best and really goes over Arizona Geology.

    Thank you !
