Sedimentary
Sedimentary rocks are most useful for historical geologists because they can contain fossils and provide information about past environments and the Earth's history. Sedimentary rocks also often preserve layers that can be used to determine the relative age of rock formations.
Geologists study the Earth, including Earth's surface and interior. Geologists study the origin, history, and structure of Earth and the processes that shape it over time. A geologist is a contributor to the science of geology. Geologists study the physical structure and processes of the Earth. Their undergraduate training typically includes significant coursework in chemistry, physics, mathematics and possibly Biology, in addition to classes offered through the geology department; volcanology, hydrology, and rock and mineral formation are among the many areas of study. Most geologists also need skills in GIS and other mapping techniques. Geologists survey the rock and mineral structure of an area which can assist in finding water supplies, oil, gas, mineral resources and faults amongst other things. This information can be useful to mining companies, government agencies, construction companies and so on.
The most useful physical property when classifying a rock is its mineral composition. This includes identifying the specific minerals present in the rock and their relative proportions. By analyzing these properties, geologists can categorize rocks into different types based on their mineral content.
Geology is the study of the earth. Since much of the earth is made up of rocks, most geologists spend time studying how the rocks change over time, along with their history and formation.

The most useful physical properties for identifying minerals are color, luster, hardness, cleavage, fracture, streak, and specific gravity. These properties help geologists distinguish between different minerals based on their unique characteristics.
