Eucalyptus trees have been found to contain trace quantities of gold.
According to research findings published on January 23, 2020, while money might not grow on trees, gold can indeed be found within them. Specifically, eucalyptus trees are known for their long, deep root systems. These roots can reach far into the Earth's surface, drawing up various substances from the soil.
How Gold Gets into Eucalyptus Trees
The unique ability of eucalyptus trees to contain gold is linked to their deep roots.
- Deep Root Systems: Eucalyptus roots can extend significantly underground, reaching depths of up to 110 ft (33 m).
- Absorption of Minerals: As the roots search for water and nutrients, they also absorb trace quantities of minerals present in the soil and bedrock.
- Gold Uptake: When gold is present in the ground at these depths, even in tiny amounts, the roots can draw it up into the tree's vascular system.
This phenomenon means that while you won't find gold nuggets hanging from branches, very small amounts of gold atoms can be detected within the tissues of eucalyptus trees that grow in gold-rich areas. This discovery has potential applications in mineral exploration, allowing scientists to use trees as indicators for underground gold deposits.
