Some rocks will be made up of grains that are all the same size (or very close), while others will have a variety of grain sizes In sedimentary rocks, we refer to uniform grain sizes as ‘wellsorted’ while rocks with a variety of grain sizes are referred to as ‘poorlysorted’ It’s also important to observe the shape of the grains61 Clastic Sedimentary Rocks A clast is a fragment of rock or mineral, ranging in size from less than a micron [1] (too small to see) to as big as an apartment block Various types of clasts are shown in Figure 531 and in Exercise 53 The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock61 Clastic Sedimentary Rocks – Physical Geology – 2nd EditionLimestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%) It is the most common nonsiliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rockLimestones are rocks that Limestone Sedimentary rocks Sandatlas2024年1月7日 For instance, oolitic limestone, composed of small spherical grains called ooids, forms in warm, shallow, waveagitated waters to observe the color of its powder can also aid identificationLimestone: characteristics, formation, uses ZME Science

Geology InThe way in which a mineral breaks is determined by the arrangement of its atoms and the chemical bond between those atoms It is difficult for us to observe these bonds, but we can observe the shape and design into which minerals break A mineral that exhibits cleavage will consistently break, or cleave, along a parallel flat surface112: Lab 12 Introduction to Minerals and Rocks
