How do detritrial chemical and organic sedimentary rocks differ from one another

Hello. The main difference between detrital chemical rocks and organic sedimentary rocks is that they differ in their formation process.

Detrital is a sedimentary rock composed of lithified sedimentary particles of previous rock type.

Chemical is a sedimentary rock created by the evaporation and subsequent crystallization of mineral rich fluids.

Organic is a sedimentary rock composed of the remains lithified plant (coal), or animals (limestone)
