Rocks are labeled by 3 groups. Igneous, Metamorphic, and Sedimentary.
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
Foliated or non-foliated.
Look at them. There shape, size, color and feel! Dont worry you will figure it out....

Rocks are classified by they way they are formed. There are three main classes of rocks: igneous, metamorphic and sedimentary rocks.
Orange Calcite is found in Igneous and Metamorphic rocks.
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
they are classified into 3 major kinds of rocksthey are the ;IGNEOUS ROCKS,SEDIMENTARY ROCKS,AND METAMORPHIC ROCKS
sedimentary rocks can be classified by detrial, chemical ,or organic
classified by weathering
Plutons are classified by their size, shape and relationship to surrounding rocks ~Meag
They are classified by their composition.
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Gold is usually found in metamorphic rock but can also be found in sedimentary rock. In deep mines, quartz rock is found in association with gold.
Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.
