WebChemical Sedimentary Rocks. In this lab, you are going to describe and identify some common chemical sedimentary rocks. Your lab instructor will summarize the main characteristics of the different rocks. In the second part of the lab, you should list some possible environments in which the rocks that you identified might have formed. WebOrganically formed sedimentary rocks and chemical sedimentary rocks form in similar ways, but they are composed of different materials. While organic sedimentary rocks contain carbon from organisms that were once living, chemical sedimentary rocks consist of non-organic materials.
