If you are asking for the name of such soils, they are soils formed in residuum, or residual soils. Typically, the soil profile grades into a degraded bedrock called saprolite, with depth, before hiyting hard bedrock.
Residual soil is the soil formed from the weathering of the bedrock.
The majority of bedrock in the Catskills was formed during the Devonian Period, which is part of the Paleozoic Era. This bedrock consists of sedimentary rocks like sandstones and shales, as well as igneous rocks like granites formed through tectonic and volcanic processes during this time.
U-shaped valleys, erratic boulders and rocks, modern soils, glacial striations on bedrock, the Great Lakes in the United States, extinction events, and massive redistribution of soils and rock.
pH below 7 is termed acidic. pH of 7 is termed neutral (water). pH above 7 is termed basic or an alkaline.
Soils are typically not included in geologic maps because these maps focus on the underlying geological materials and processes, such as bedrock formations, fault lines, and mineral deposits. Soils, being a surface layer formed by the weathering of rocks and organic matter, are more variable and dynamic, influenced by factors like climate, vegetation, and human activity. Geologic maps aim to represent stable and enduring geological features, while soils change more frequently and are usually depicted in separate soil maps.
Yes, soils that are formed directly from the weathering and decomposition of underlying bedrock are referred to as residual soils. These soils typically retain similar properties and composition to the parent rock from which they originated.

Residual soil is the soil formed from the weathering of the bedrock.
Parent bedrock is an underlying geological material that soil horizons from. Soils inherit a good deal of minerals from the parent materials.
In general, the depth of soil formed from underlying bedrock is directly proportional to the length of the weathering period. Longer weathering periods allow for greater breakdown of the bedrock into soil components, resulting in deeper soils. Conversely, shorter weathering periods lead to shallower soil development.
Azonal soils include coastal soils, alluvial soils, and glacial soils. Coastal soils are formed near coastlines due to deposition of marine sediments, while alluvial soils are formed by rivers depositing sediments. Glacial soils are created by glaciers scouring and depositing materials as they move.
The bedrock that underlies the Antarctic continent was formed about 540 million years ago during the formation of the supercontinent Gondwana.
Terra rossa soils are a type of reddish-colored soil that is rich in iron oxide. They are known for their fertility and are commonly found in regions with limestone bedrock. Terra rossa soils are well-draining and suitable for agriculture.
Residual soil is formed from the same material as the bedrock beneath it through weathering processes over time. The characteristics of residual soil often mirror those of the bedrock from which it was derived.
black soil is formed from basaltic rocks
The majority of bedrock in the Catskills was formed during the Devonian Period, which is part of the Paleozoic Era. This bedrock consists of sedimentary rocks like sandstones and shales, as well as igneous rocks like granites formed through tectonic and volcanic processes during this time.
The Ozarks primarily consist of thin, rocky soils that are acidic and low in nutrients. These soils are often derived from sandstone and limestone bedrock that is weathered over time, resulting in the characteristic cherty soils of the region.
