    Radiation and Earthcaching

    in EarthCaches

    Posted · Edited by danieloliveira

    The weathered zones of primary uranium deposits are normally much easier to identify in terms of their mineralogy. If you've got remobilisation (and inevitably you do) of uranium minerals then you should be able to find other secondary minerals such as Torbernite [Cu(UO2)2(PO4)2·8-12(H2O)] and Carnotite [K202UO3V2O5nH20]. These invariably have striking colours; the former is bright bottle green and the latter bright yellow and might be easier to identify. I don't know if these show up at your location.

     

    Let me add another thought:

    In Portugal the previously exploited uranium mines are located in schist-greywacke complexes close to the exocontacts of major granitic bodies.

    Remember also that granites have natural radiation associated with them. If I remember my old prof correctly around 20 ppm of uranium that will certainly give you a very small kick on a Geiger Counter. However, if you find fluid conduits (faults, fractures and the like) within the granitic body, these areas will invariably give you much higher kicks on your GC.

    If these GC's were cheap then your problem would be solved: measure the c/s value at coordinates x and y.

    Introducing Trackable GeoGold™

    Got mine today. Disappointed in that it does not have a unique icon. Is this going to change?

     

    what does the back side look like as we still haven't seen a picture or read a description?

     

    thanks!

    The back side says geogold

    number

    track at geocaching .com

     

    side is also gold coloured, completely flat.

     

    Yup that is correct. The backside is nothing much to look at but the front is a perfect reproduction of fluvial gold nugget as you can see from the pictures above.

    Eu já sou douradinho! :o

     

    Da Igloo? :blink:

    Eu também sou. tenho muitas feitas mas poucas encontradas :o

     

    Até que não são mauzinhos de todo (os douradinhos) :huh:

     

    Eu estou ao contrário, já tenho algumas encontradas (imagina quem é o owner da maioria delas :blink: ) e poucas feitas.

     

    Acho que falta fazer mais uma para ser platina. :o

     

    ENA! Força.

    TYPES OF CACHES

    in Australia

    Posted

    I must say that micros should only really be hidden in places where there are few hiding places or that the affluence of people is so great that a diminutive size will go by unnoticed (we hope).

    unfortunately I have been caching in places where you can hide an elephant only to find a micro hidden in some stone wall :)

    This them makes me wonder if the geocacher lives nearby. If they do then maintenance is easily carried out. However, in some cases they don't and then inevitably the logbook gets full and the cache lapses into abandon.

    I know of several cases where cacher are holidaying in a particular location, they find it pleasant enough to hide a cache, and the only thing they have in the car is a film canister and it gets planted.

     

    Think before hiding a cache, please.

    Apanhei-te Daniel Oliveira (não posso dizer mal pois acabas-te de me dar uma nota imerecida da Beds!)

     

    Esqueci-me de desligar enquanto fazia aqui um desenho para te convencer.

    You have mail.....

    As EarthCaches em Portugal

    in Portugal

    Posted

    :) Já estavam à espera desta não estavam? :blink:

    Não consigo passar muito tempo sem falar das EarthCaches....... mas gostava de ouvir a opinião de quem as faz e cria.

    - Têm algum gozo em fazê-las?

    - servem para alguma coisa? ou é só mais um found?

    - Qual a vossa melhor que fizeram até hoje? Seja em Portugal ou no estrangeiro.

     

    Com toda a honestidade....

     

    1) Acho que o Geocaching não devia priviligiar a Geologia (creio que o conceito de Earthcache ultrapassa o limite da geologia, mas em termos prácticos nem por isso) abrindo excepção para a criação de caches virtuais. Porquê Earthcache e não Historycache ou Zoocache?

     

    2) As Earthcaches que conheço baseiam-se numa pipa de teoria, maçuda, aos moldes dos velhos compêndios escolares. Creio que toda a gente ficaria a ganhar se a informação fosse apresentada de forma ligeira e de fácil digestão. Se calhar digeria-se mesmo e a mente alimentava-se. Assim, dá-me a ideia que o pessoal vai directo ao assunto e poucos aprendem. Conhecem o sketch dos Gato Fedorento chamado O Maçador de Toiros?

     

     

    Aquilo chegando ao 2:06 faz-me mesmo lembrar os textos de algumas Earthcaches.... Teremos os Maçadores de Geocachers ? :-)

     

    Obrigado Ricardo.
