Facts About. A large, showy lily, Canada lily is pollinated mainly by the ruby-throated hummingbird. Recently, an introduced beetle, the lily leaf beetle (Lilioceris lilii), has been detected feeding on native lilies including Canada lily. This beetle could have strong impacts if it continues to spread.
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in Bowen's reaction series. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black.
Sandstone Basics. Sandstone is a category of rock made from sediment (a sedimentary rock). The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock.andstone with a lot of matrix is called poorly sorted. If matrix amounts to more than 10 percent of the rock, it is called a wacke (wacky). A well-sorted sandstone (little matrix) with little cement is called an arenite. Another way to look at it is that wacke is dirty and arenite is clean.
