    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!!!

    I will contact some of the retired geologists in AZ I know and ask.

    Some referred me to this club http://centralarizonageologyclub.blogspot.com/     

    Unfortunately they meet in Prescott but you might be able to make online 

    friendships and find someone, especially a retiree, that may enjoy sharing

    what they've learned.  My father, a retired a petroleum geologist, taught me all I know.

    Though he is no longer with us, I continue to prospect, hearing his voice advise and guide me.

    Of course you know the AZ Geological Survey http://www.azgs.az.gov/   That's probably where you get 

    info that sometimes make your head spin. LOL. Good luck. Will let you know what I find out!

    Thank you so much Susan!

    I am thinking about sending the AZGS an email, and seeing if there are any geologist out there who would enjoy a day out in the field having some fun. I always love sharing my knowledge with people, and don't know why a geologist wouldn't want to.

    please let me know what you find out.
