Sedimentary Rocks and their processes

sedimentary rocks are especially important for deciphering Earth history. • Much of our knowledge of the evolution of life on Earth derives from fossils preserved in sedimentary rocks. • Some sediments and sedimentary rocks are resources in their own right, or contain resources.

The Rock Cycle: Igneous, Sedimentary, and Metamorphic

The rock cycle is a continuous process describing the transformation of the rocks through various stages through their lifetime. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over.

Sedimentary Structure

Four sedimentary units have been identified: Unit 1, through Unit 4, in ascending order. The lower boundary of each unit is clearly erosional, as indicated by scouring (Figs. 5.5 and 5.6). Furthermore, a reworked unit was occasionally found on the top of Unit 4; this cover was caused by river flooding after the tsunami sedimentation (Fig. 5.7).

Types of Rocks

20-3-2017There are three basic types of sedimentary rocks: Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.
