Henry David Thoreau said geology is where we “discover the causes of all past changes in the present invariable order of society.” In so many ways science﹘be it chemistry, geology, astronomy, or biology﹘is the study of change over time; the intense pressure put upon a subject causing it to evolve from one state to another, and to grow from there.
As a scientific species, we experience time travel not only when we send probes into space to experience the relativity of time and space, but each time we put a rock under the microscope. At Asphalt Materials, we love the stories that rocks tell. Each one teaches us about what occurred in our valley millions of years ago and helps us appreciate the natural beauty found all over Utah. Over the years our customers have grown to value our various landscape supplies, and our various rock and sand options have elevated our asphalt company beyond just making blacktops.
In order to better understand the rocks we sell (and why we love them), let’s travel back in time and see how they were formed. It’s important to note that all rocks are the product of heating, cooling, and compacting of specific minerals and chemicals. Depending on the manner of their creation, all rocks fall into one of three distinct categories.
Some of our most popular rocks for landscaping are igneous, thanks to their brilliance and color. We offer everything from pitch black lava rocks to shimmering quartz rocks, in order to decorate your yard in a unique and timeless way.
As the name suggests, sedimentary rocks are created as sediments, sand, and other broken pieces of rock are layered on top of each other and hardened over millions of years. Like looking at the rings of a tree, we can chart the path of each of these rocks by looking at the lines of sediment and determining what happened in the area. Utah is particularly well-known for it sedimentary rocks, and famous examples include the red rocks of Bryce Canyon and the stripes of the Delicate Arch in Arches National Park. We also deal in sedimentary rock, offering stunning decorative options like our Sunburst sandstone.
Thanks to the way in which they were formed, sedimentary rocks are perfect for housing fossils because the remains could simply be piled over as the millennia drew on. Generally speaking, the rocks are also relatively soft and have been known to break apart without much force. This makes the great natural formations in our state extremely delicate. These qualities of sedimentary rocks are not just great at teaching us about the steady flow of time but are also the best rocks to connect us to the earliest life on earth. Each stone is a paradox: lifeless pieces of flagstone, shale, or chalk, and yet formed and shaped by ancient animals and water flows.
In Franz Kafka’s seminal work The Metamorphosis, he writes about a man who “awoke one morning…
Metamorphic Rocks are a great example of Mother Nature’s dominance over the planet﹘even stone is subject to her whims, and cannot maintain integrity if not given a chance to escape. We sell numerous types of metamorphic rock, usually the quartzite that supplements our other igneous and sedimentary rocks to create a more dynamic spectrum of beautiful options for our customers to choose from.
