Your fictitious outcrop must have at least three of the following characteristics: sedimentary structures, hydrothermal alteration, igneous plutons, fossils, contact metamorphism, minerals from Bowen's reaction series, or foliation. Describe your outcrop with at least the following information:Which of the three rock types are present?
- Which specific rocks (e.g., sandstone, granite, etc.) are present?
- What characteristics are present in your outcrop?
- In what type of environment did each of your characteristics form (e.g., sedimentary depositional environment, metamorphic conditions, in the crust, on the surface, etc.)?
Further investigation has been done on the rock outcrops surrounding the Terra Mater rock formation that found proof of life on this distant planet. Due to the volcanic eruption that is believed to have ended the life on Terra Mater, as shown by the fossils that were found, there is a heavy presence of metamorphic rock in the area. Extrusive Igneous rock formations have also formed due to the "cooling and crystallization of the magma" (Earle, p70) from the volcanic activity. Using the Bowens reaction series as guidance, and due to the Basalt, that was found, we found that this cooling happened on the surface. The other rock that is abundant in the area, sedimentary rock, was found below the thick metamorphic rock. The sedimentary rock is mostly made up from sandstone and limestone that was compressed from the weight of the metamorphic rock deposited on top of it by the eruption. The presence of the limestone may also indicate that a large body of water was in this area and evaporated forming the limestone.
In the above fictitious planet description, what are some positive things that you noticed, and also was it descriptive enough?
