Further mechanical weathering along these joints leads to pealing off of slabs and converting the pluton into an exfoliation dome. 2. Chemical Weathering: It is a process of alteration of rocks of the crust by chemical decomposition brought about by atmospheric gases and moisture.Groundwater occurs within fractures of crystalline hard-rock. Mostly, these fractures are covered by weathered rocks; therefore, delineation of their spatial position is a challenge task. Geophysical methods are widely used to obtain subsurface geological information in the weathered terrains. However, use of single geophysical method may …5.3: Sedimentary Rocks Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. They are classified by grain shape, grain size, and sorting.6.
