What is true about the texture of all detrital sedimentary rocks?

Answer 1

Clastic rocks have a 'clastic texture', which means they consist of clasts. The 3D orientation of these clasts is called the fabric of the rock. Between the clasts the rock can be composed of a matrix or a cement (the latter can consist of crystals of one or more precipitated minerals). The size and form of clasts can be used to determine the velocity and direction of current in the sedimentary environment where the rock was formed; fine, calcareous mud only settles in quiet water, while gravel and larger clasts are only deposited by rapidly moving water.[10][11] The grain size of a rock is usually expressed with the Wentworth scale, though alternative scales are used sometimes. The grain size can be expressed as a diameter or a volume, and is always an average value - a rock is composed of clasts with different sizes. The statistical distribution of grain sizes is different for different rock types and is described in a property called the sorting of the rock. When all clasts are more or less of the same size, the rock is called 'well-sorted', when there is a large spread in grain size, the rock is called 'poorly sorted'

Answer 2

Detrital sedimentary rocks are typically composed of mineral and rock fragments that are transported and deposited by water, wind, or ice. These rocks tend to have a clastic texture, with particles that are often angular or rounded depending on the distance traveled and the energy of the transporting agent. Detrital sedimentary rocks usually exhibit a layered structure due to the distinct sizes and compositions of the particles deposited.
