Plants growing around gold deposits

However the topic of indicator plants for gold and many other minerals is interesting and i have read a little on it. Geobotany is used by some mining companies and especially the use of false colour imagery from aerial photography to pick up discolouration in plant leaves that indicates the presence of minerals. Plenty of serious work has been ...

On the Origin of Gold | Science Mission Directorate

Where did the gold in your jewelry originate? No one is completely sure. The relative average abundance in our Solar System appears higher than can be made in the early universe, in stars, and even in typical supernova explosions. Some astronomers have suggested, and many believe, that neutron-rich heavy elements such as gold might be most easily made in rare neutron-rich explosions such as ...

Glycoside - Wikipedia

In chemistry, a glycoside / ˈ ɡ l aɪ k ə s aɪ d / is a molecule in which a sugar is bound to another functional group via a glycosidic bond.Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use.
