Rock Classification Chart Learn how to identify and classify igneous, sedimentary and metamorphic rocks using visual guides, diagrams and tables. find out the characteristics, compositions, textures and distinctive properties of different rock types and grades. Learn how rocks are classified into three types: igneous, sedimentary and metamorphic. see the basic characteristics and examples of each rock type and how they form.
Rock Classification Chart Learn how to identify and classify rocks based on field and petrographic tests, and how to describe their physical properties for engineering purposes. see charts, diagrams, and examples of igneous, sedimentary, metamorphic, and pyroclastic rocks. Use this diagram to distinguish between gabbro and norite, or if your rock is mostly plagioclase and pyroxene with little to no olivine or hornblende. use this diagram if your mafic rock contains hornblend. use this diagram for rocks with less than 10% plagioclase that do not contain hornblende. Public domain. Learn how rocks are classified into three major types based on how they form: igneous, sedimentary, and metamorphic. explore the properties, characteristics, and uses of each type, and the concept of anthropic rocks.

During the feasibility and preliminary design stages of a project, when very little detailed information is available on the rock mass and its stress and hydrologic characteristics, the use of a rock mass classification scheme can be of considerable benefit. Select a rock, and take the appropriate path below to classify the rock. in each of the sections, you will find brief descriptions of textures and mineral compositions, and a classification chart based on these characteristics. Rock types or groups of rock types are defined by boundary conditions that will generally follow natural or well established groupings. well established rock names are retained wherever possible, although some terms are more rigorously defined. the scheme is essentially hierarchical. List of rock types the following is a list of rock types recognized by geologists. there is no agreed number of specific types of rock. any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
