How would today's sediments appear to a geologist millions of years in the future examining outcrops of sedimentary rock that originated in our time?This chapter is an introduction to rocks and minerals, and the rock cycle.Basic chemistry is important to all sciences, especially geology!The principle of inclusions states that inclusions found in other rocks (or formations) must be older than the rock that contain them. Geologists call it relative dating — we know which one is older but do not know how old they are.
This is actually pure logic and it can be applied not only in geology, but it is especially useful for geologists. Inclusions of foreign rocks that are found in igneous rocks are named xenoliths.Disconformity – strata on either side are parallel c.
