    the sedimentary rocks that form the surface rocks of southern Ontario. These sedimentary rocks were deposited on older Canadian Shield rocks when shallow inland seas covered the region about 550 to 350 million years ago. The scenery of Muskoka and Georgian Bay is very different from that of southern Ontario because of different geology. And why is there so little soil on these rocks? Glaciers ...

  • Sedimentary rock - Texture | Britannica

    Sedimentary rock - Sedimentary rock - Texture: The texture of a sandstone is the sum of such attributes as the clay matrix, the size and sorting of the detrital grains, and the roundness of these particles. To evaluate this property, a scale of textural maturity that involved four textural stages was devised in 1951. These stages are described as follows.

  • Sedimentary rock - Wikipedia

    Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment ...

    "On Earth, sedimentary rocks preserve the surface history of our planet, and within that history, the fossil record of life. It is reasonable to look for evidence of past life on Mars in these remarkably similar sedimentary layers," said Malin. "What is new in our work is that Mars has shown us that there are many more places in which to look, and that these materials may date back to the ...
