What are the types of clastic rocks?
Clastic Sedimentary rocks can be classified on the basis of grain size as: 1. Rudaceous 2. Arenaceous 3. Argillaceous
What is the name used to refer to all fine-grained sedimentary rocks?
Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).
How fast do coarse grained and fine grained rocks cool?
If the rocks are igneous then in general:- Coarse = slowly. Fine = fast. However if the rocks are metamorphic or sedimentary then grain size has nothing to do with cooling and indicates other things.
What is the name of a sedimentary rock usually based on?
The name of sedimentary rock is usually based on it's grain size.
What is the particle size of clastic sedimentary rocks?
Shale is composed of the smallest particles of other rocks.
What are a couple of examples of sedimentary rocks?
Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.
