Fossiliferous dolostone

is clasts between 1/16 and 2 mm in size, and gravel is greater than 2 mm. Chemical Rocks Chemical sedimentary rocks are identified by identifying the mineral from which they are composed. In this lab there are four minerals that need to be identified - quartz, halite, gypsum and calcite. Quartz has a hardness of 7 and is very difficult to scratch, even with a good quality ….
