Step-by-step explanation:
b. The re-precipitation of minerals in a sedimentary rock, resulting in the formation of new mineral assemblages and the transformation of the rock over time.
Diagenesis refers to the physical, chemical, and biological changes that occur in sediments after they have been deposited but before they are fully lithified into solid rock. During diagenesis, minerals in the sediment may dissolve and re-precipitate, new minerals may form, and changes in temperature, pressure, and chemical composition can alter the original sedimentary features. These diagenetic processes play a crucial role in the ultimate formation and characteristics of sedimentary rocks.
