The geologic time scale was initially developed by determining the relative ages of rock units, first in Europe, and then in other parts of the world. Most of this work was done in the s and s. To determine which rock units were older and which ones were younger in a relative sense , geologists devised a number of laws, or principles, to help figure out the sequence of geologic events in a particular locality. In this lab, you will apply many of these laws and principles to determine the relative sequence of geologic events that created a particular set of rock layers and intrusions. By doing this, you will unravel the geologic history recorded in the rock record, just as geologists did hundreds of years ago, and still do today.
