Every rock has a story to tell.
Geologists study the microscopic world of rocks in order to better understand the earth's history.
This type of rock exploration follows a logical sequence. The first step is to identify the minerals that compose the rock . Minerals can be difficult to identify with the naked eye, but they have characteristic optical properties that are easily distinguished under the microscope. Some of these properties are color , cleavage and twinning . The next step is to describe the architecture of the rock.
