What minerals make up siltstone?
Siltstone is a sedimentary rock composed of cemented silt-sized particles of quartz and feldspar, primarily.
Detrital sedimentary rocks are classified (named) primarily on the basis of?
Detrital sedimentary rocks are primarily classified based on the size, shape, and composition of the sediment particles that compose them. Common classifications include sandstone (made of sand-sized particles), siltstone (silt-sized particles), and shale (clay-sized particles). The mineral composition, such as quartz or feldspar content, also plays a crucial role in their naming and classification.
How do you distinguish wackes and arenites?
Wackes are sedimentary rocks with a mix of sand- and silt-sized particles, while arenites are predominantly composed of sand-sized particles. The presence of a significant amount of finer-grained matrix material, such as silt or clay, in a rock indicates wackes, while arenites are mainly made up of sand-sized grains that are not visibly mixed with smaller particles.
A thinly layered rock composed of clay-sized particles is a?
A thinly layered rock composed of clay-sized particles is a type of sedimentary rock called shale. Shale is formed through the compaction of clay and silt-sized particles over time.
Is siltstone a medimothic igneous sedimentry?
Siltstone is a sedimentary rock, not an igneous one. It is composed primarily of silt-sized particles, which are finer than sand but coarser than clay. Siltstone typically forms from the compaction and cementation of silt particles, often in quiet water environments like lakes or floodplains. It is classified as a clastic sedimentary rock due to its composition and formation process.
What minerals make up siltstone?
Siltstone is a sedimentary rock composed of cemented silt-sized particles of quartz and feldspar, primarily.
Soil is made of what silt sized particles?
Silt soil is made up of medium-sized particles that are larger than clay particles and smaller than sand particles. Silt particles are smooth, fine-grained, and retain water well while also offering good drainage. Soils with a high silt content are typically fertile and suitable for farming.

Loess is made up mainly of?
Loess is made up mainly of fine-grained particles such as silt and clay, with some sand and larger rock fragments. It is typically formed by the accumulation of wind-blown dust over time.
What is a medium sized soil particle that feels silky?
Silt is a medium-sized soil particle that feels silky when rubbed between your fingers. Silt particles are smaller than sand grains and larger than clay particles, giving it a smooth texture.
Why most of the silt in the Mississippi delta is found farther out to sea than the sand-sized particles are?

What are the different sized particles of soil?
Soil particles are classified based on size: sand particles are the largest, followed by silt, and then clay particles are the smallest. Sand particles are between 0.05mm and 2mm in diameter, silt particles are between 0.002mm and 0.05mm, and clay particles are less than 0.002mm in diameter.
What are the four main classes of soil?
The four main classes of soil are sand, silt, clay, and loam. Sand particles are the largest, silt particles are medium-sized, and clay particles are the smallest. Loam is a mixture of sand, silt, and clay, and is considered the most ideal soil type for plant growth.

A thinly layered rock composed of clay-sized particles is a?
A thinly layered rock composed of clay-sized particles is a type of sedimentary rock called shale. Shale is formed through the compaction of clay and silt-sized particles over time.
What are silt particles cemented together?
Silt particles cemented together form a sedimentary rock known as siltstone. Siltstone is composed mainly of silt-sized particles compacted and cemented over time. It has a fine-grained texture and is commonly found in layers or beds in sedimentary rock formations.
