Do You Know Why Nuggets Are Smooth And Rounded?

Recommended Posts

Many believe that the nugget gets rounded by it tumbling about.  I have a large specimen that is flat on one side and I've always believed that it is that way because other objects passed over it as it stayed in place.  This article confirms that for Blackwood, Australia and says:

‘A feature of many of the goldfields of Victoria was the finding of large masses of gold nuggets.  They varied in size, and were not confined to any particular class of washdirt, nor with any regularity as to depth, but, from their disposition in restricted areas, certain belts can be regarded as typically nugget bearing.  On account of the soft character of gold, nuggets of any size are always well rounded.  This is due to the attrition of material passing over the nugget rather than rounded by rolling action.  Many of the large nuggets had one side relatively flat, while the other was well rounded.  Some of the nuggets were coated with oxides of manganese and iron; several had quartz attached to them, while a few were of ragged and roughly crystalline appearance.’

These sorts of descriptions are so hard to fathom.  It must have been an amazing thing to see.

Just seeing what Reg was plucking out of the ground back when was hard to fathom! Not only a Porche 911 but two!

      Why does California have so much gold that is seemingly just laying not far below the surface of the topsoil?

      I had posted the following in another thread recently but it did not get much traction maybe because the thread was about something totally different? LOL 
      If you have an opinion let's hear it! This thread is not titled for experts only!
       
      I wonder if there is a difference in performance in tailings depending on the type of tailings. Do we need to differentiate between hard rock tailings and placer tailings when talking about the relative merits of PI versus VLF. For instance tailings from ancient river deposits as opposed to a hard rock tailings deposit consisting of iron rich ultra-mafic rocks. Or is it a moot point in all ground types of hard rock tailings due to no electrical conductivity in hard rock tailings because they are busted up? I think quartz tailings can be very benign almost to the point of an inability to GB on them.
      In regard to depth on tailings  between PI/VLF being basically equal, is that true in all instances except for say a GPX or GPZ due to the battery power enabling a much higher level of gain? Like VLF = TDI but VLF < GPX?

      Steve, Can you explain why Tailing piles are lower in mineralization compare to other areas, And would the Tailings at place's like Moore's Creek be Hotter than The Tailings Ganes Creek,
       
      What Cause's them to be Lower than the general Detecting Areas is it Because they are made up of disturbed Ground??
       
      Thanks,,, John

      A mining company called Integra is offering a $1 million prize to process their 6 terabytes of data and make a new big gold discovery in a hard rock property they purchased in Canada.

      If anyone is into mapping, exploration, geology, hard rock mining, and data processing with computers then this may be something you are interested in. We're obviously all interested in gold already! Seems like there are a few mining engineers and geologists that post on various gold forums.

      The state of wy is doing a pine tree clear-cut over top of a potential gold rich zone north of the old miners delight mine, doing so in the name of better habitat for the quakies.
      This seems a little wierd to me, so i ask if anyone knows if removal of decidous? trees would greatly increase effectivness of such a survey?
