Abstract: A cleaning composition and method for the removal of contaminants, such as, oil and grease from a surface, particularly concrete and asphalt. The composition includes an absorptive material, charcoal, and a pH modifying agent which is applied and removed in a dry form.
Sedimentary rocks form when particles of sediment are deposited by water or wind, and then (in most cases) hardened or consolidated through time. Shale, sandstone, and limestone are types of sedimentary rocks that often contain fossils.ven though a relatively small proportion of plants and animals that live are preserved as fossils, because so many animals live and die, and because sedimentary rock is very common, finding fossiliferous (fossil-bearing) rocks is not very difficult.
Ancient History A very few of the sedimentary rocks of the Carolina Slate Belt in South Carolina contain fossils of Cambrian age (about 500 million years old). They are referred to as âGondwananâ because they resemble Cambrian fossils found in the southern continents rather than those in North America.ncient History A very few of the sedimentary rocks of the Carolina Slate Belt in South Carolina contain fossils of Cambrian age (about 500 million years old).
