Bell Ringer: Describe 3 features of the rocks in this picture. Pick features you think are clues to the story of how these rocks formed.

2. This small Jack Hills zircon (50 micrometers is about the width of a human hair) crystallized slowly. The crystal grew from the core (left) to the rim (right). As crystals form, they incorporate chemicals from their surroundings. (Image courtesy Bruce Watson, Rensselaer)
The roughly 80-kilometer-long formation is a collection of bits and pieces of greatly eroded sedimentary and metamorphic rocks such as chert, sandstone, and quartzite.  
Individual crystals of zircon within the rocks are 4.4 billion years old, only 150 million years or so younger than the age of the Earth itself. These crystals are the oldest fragments of the Earth yet found. (Photograph copyright Bruce Watson, Rensselaer)

Bell Ringer: This is a photo of Rainbow Mountain in Peru. What do you think is causing the rock in this mountain to be a rainbow of colors? This about what is in rocks and how different types of rocks form.
The local area is rich in geology, from uplifted granitic cliffs to glaciers which have eroded large valleys and the cretaceous limestone "forest" nearby.
The Andes are an incredibly complex mountain chain that extends along the western edge of the South American continent. The subduction of the Nazca plate underneath the South American plate initiated mountain building and uplift of the mountain range. This produced significant volcanism and the introduction of rare and varied mineralogy to the Andes Mountains.
The reason we see the rainbow coloration in the stratigraphic layers of the Ausangate mountain is largely due to weathering and mineralogy. Red coloration of sedimentary layers often indicates iron oxide rust as a trace mineral. Similar to how a nail will rust and turn red when oxidized, sediments that are iron rich will change when exposed to oxygen and water. This, in combination with uplift and tectonically driven crustal shortening has tilted the sedimentary layers on their side exposing stripped stratigraphic intervals.
The different coloration is due to different environmental conditions and mineralogy when the sediment was originally deposited and subsequently diagenetically altered. Introduction of goethite or oxidized limonite will introduce a brownish coloration to sandstones. The bright yellow coloration could be due to iron sulphide as trace minerals within the pore cement. In addition, chlorite will often color sediments varying shades of green dependent on diagenetic history and concentration.
