ANDESITE - LIMONITE ?
Oh, those iron altered rocks.
Aside of solid iron rocks seen in a few ofDarmar's photos, obviously indigenous iron host rock, but when it comesto the Ansdesite and Limonite descriptions i couldn't help but think of, Siderite iron rock.
In this region, and on the fringe of the - Easrern B.C. Cordillera - Siderite exists.
Siderite has a carbonic nature - which remined me of Copper Mountains sodic influence and along with calcite .
When looking at pics ( web ) that decribe Andesite or Limonite - i can't help but think of,
the altered species of iron ( must ) have a glue inwhich to keep itself together.
Though these secondary formed iron rocks don't spell out a carbon formula i would have to question a labelling of such rocks - in fact one rock i seen online labelled - limonite actually had a carbon value leaching aside of it - which ceertainly points to a carbonic glue that holds and binds the oxidized irons together.
Why mention all this ?
All because - oxidized iron in loose sands is seen at surface al lover thisPrinceton district.
Not much to go on... but, looking for a siderite or Limonite, Andesite that has a carbonic glue would certainly be a great pathfinder in which to locate where the sodic or carbon influence is more promient - coming up from benieth. This region as per Copper Mountain's report - has a strong alkai intrusion or influence. Find the carbons = finds the copper.
Just thought i'd mention this...
Last post correction -
- jacket on ground = angle and pitch is seen in vein, or, sediment sheet.
- plastic bag on ground quartz - carbonc = intrusion ? ( pipe )
But... a
