Geologic Time

Geologic Time By examining layers of sedimentary rock, geologists developed a time scale for dividing up earth history. Earlier in the 20 th century, radiometric-dating techniques allowed scientists to put absolute dates on divisions in the geologic time scale.

Relative Dating

Relative Dating. Original Horizontality. Layers of sediment are deposited evenly, with each new layer formed horizontally over older layers. Superposition. In an undeformed sequence of rocks, each layer is younger than the one below. Cross Cutting.

Relative Age Dating

Relative Age Dating. Unconformity = any gap in the rock record 1. Angular Unconformity = younger, flat strata above older, eroded/tilted sedimentary rock. Angular Unconformity. Relative Age Dating. Nonconformity younger, flat strata above eroded, older metamorphic/igneous rocks.

Who we are

Who we are. Geologic materials. Rocks (including high and low porosity & crystalline), unlithified or poorly lithified sediments, and soils. Form when the rock forms, thus provide a record of geologic processes May be present in sedimentary, volcanic, and intrusive rocks
