Specularite

This suspension bridge has some unique features, and has been named after a form of specularite, unique to this location.

Specularite is a special form of hematite, shiny, sparkling and mirror-like.

Hematite is one of the most abundant minerals on the earth's surface, and the most important ore of iron. It is an iron oxide with a chemical composition of Fe₂O_3 .  

Specularite, or specular hematite, has a beautiful metallic lustre. Even though this form of hermatite has a silver colour, it still produces a reddish streak, which is how it is identified.

Specularite was thought to have been formed about 2.4 billion years ago. Earth's oceans were rich in iron, but it wasn't until bacteria became capable of photosynthesis and released free oxygen into the ocean environment, that the iron combined with oxygen and hematite was first formed. 

So, the specularite found here is potentially billions of years old and unique in this area.
