Gold Can Grow on Trees

Gold Can Grow on Trees

2. Scientists in Australia have recently discovered that tiny amounts of gold are actually inside certain leaves. The amount inside the leaves is so small though, that it is not even worth mining. However they have also discovered that, the trees that have gold in the leaves, grow above a gold deposit deep within the ground. Trees have been found with gold in them, with the gold buried more than 30 meters below ground. This technique to find minerals is called biogeochemical prospecting and has been used to find millions of tons of minerals deep beneath the regolith.

I chose this because, the title caught my attention, and as I read it I thought it was really cool how they actually found large amounts of gold beneath the trees.

3. I saw that this is based on evidence from how they used a powerful microscope to see the gold.

I saw the role of chance from how they are not sure which trees will have gold, so they have to test a lot.

I saw the role of curiosity from how they decided to mine under these trees where they found the gold.

  1. I thought that this article was interesting and might help miners find gold deposits easier

  2. This article on CNN goes a little more in depth about the gold growing on the trees. It talks about how it happens, why it happens, and which trees it is most common in. Here's the link: http://www.cnn.com/2013/10/22/world/gold-growing-on-trees/

  4. Wow this was amazing to read about. I think it is really cool how you can find out about something so deep about looking at leaves on a tree. I was doing a little extra research and found that scientists have tested many materials with different species of trees. For instance, it is very easy to notice zinc in the organ of oak trees, but it is much harder to notice the uptake of copper in these trees. I think it is so cool that someone would think to test the trees for materials far beneath the earth's surface

  5. This article was interesting to read because it made you think about other possibilities of how this can be used. I also had no idea that plants absorb all that's around them, including minerals.
