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.
 +++  Fossils do not form into sedimentary rock, but as th â¦ e question  says, are in many, though not all sedimentary rocks. A fossil is  the cast of a dead organism whose decayed-away tissues or bones are  replaced by minerals in the parent sediment.Oil and coal are fossil fuels formed from organic debris, but  other fossils do not turn into them.  .  Metamorphic rocks are formed from any other rock by heat and/ or  pressure, not necessarily by heat alone; but metamorphism generally  destroy any fossils in sedimentary rocks undergoing the change.
