* Glacial Till: The most common rock type in Surrey, formed from a mixture of clay, silt, sand, gravel, and boulders deposited by glaciers during the last ice age.
* Fluvial Sediments: These are deposits of sand, silt, and gravel laid down by rivers, particularly the Fraser River.
* Marine Sediments: These include deposits of sand, silt, and clay that were formed in the marine environment when the Fraser Lowland was submerged under the sea.
There are also some smaller deposits of igneous rocks in Surrey, but they are relatively rare. These include:
* Volcanic Rocks: Remnants of volcanic eruptions that occurred millions of years ago, primarily found in the southern parts of Surrey.
It's important to note:
* Surrey's geology is complex and the distribution of different rock types is not uniform.
* While most of Surrey is covered by sedimentary deposits, there are areas with different rock types, such as the Fraser River Delta and the South Surrey Hills.
If you're interested in learning more about the specific geology of Surrey, I recommend checking out resources from the Geological Survey of Canada or the British Columbia Ministry of Energy, Mines and Petroleum Resources.
