3. Weathering Geological Introduction

Erosion will eventually bring these large igneous rock masses to the surface reducing dramatically the surrounding pressure and causing them to break into large blocks. Since the weathering will be most intense at the block corners, these, with time tend to become rounded and the decomposition more concentric, causing a pealing effect like an onion (exfoliation). This is well illustrated in figure 36. where one can see examples ranging from blocks with barely rounded edges, to blocks

01/05/2009· According to some authors (Briceño and Schubert, 1990) the area was moulded during a period of arid climate that can be referred to the severe continental conditions that occurred before the separation of South America from Africa (Triassic–Jurassic). An arid or semiarid climate probably persisted even during the first phase of continental rifting. Regional uplift and the rearrangement of

Laterite Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which
