A siltstone is one variety that consists of silt-sized fragments. A shale is composed of clay sized particles and is a rock that tends to break into thin flat fragments (See figure 7.6e in your text). A mudstone is similar to a shale, but does not break into thin flat fragments.The arranging of elements in a particular order is known as sorting. An efficient method of sorting is shell sort in python. It is derived from the insertion sort algorithm. In this, insertion sort is first applied to the elements that are farther away from each other and then applied to the elements that are at a less separation.Types of Rocks Grain Size Roundness Sorting Rock Name Shale (Layered) Claystone (Massive) Silt: Well Rounded: Very Well Sorted Siltstone: Well Rounded; Very Well Sorted Quartz Arenite Angular: ...
