Lithology 7. The naming of a lithology is based on the rock type. The three major rock types are sedimentary, igneous, metamorphic. Sedimentary rocks are further classified by whether they are siliciclastic or carbonate. Siliciclastic sedimentary rocks are then subcategorized based on their grain size distribution and the relative proportions of quartz, feldspar, and lithic (rock) fragments. Carbonate rocks are classified with the Dunham or Folk classification schemes according to the constituents of the carbonate rock. The name of an igneous rock requires information on crystal size and mineralogy. This classification can often be performed with a QAPF diagram. Metamorphic rock
Area of Natural and Scientific Interest occur within national parks, provincial parks, or conservation reserves". These may also be nationally or internationally significant features. An Earth Science area is one in which the representative feature was created by geologic processes and consists of the physical elements of a natural landscape, such as the bedrock, landforms, and fossils. These are identified by lithology, paleontology, and geomorphology, then classified "into geological themes" according to age, stratigraphy, topography, and other characteristics. A Life Science area is one in which the representative feature consists of the biodiversity of the area and its landscapes, and has not been affected by human
