Whats the difference in graded bedding and cross bedding?
Surfaces between layers of sediments (bedding planes) are usually deposited in horizontal sheets, but cross-bedding is inclined. Graded beds are horizontal and are usually sorted from coarse at the bottom to fine at the top.
Sedimentary rocks are separated by a lines of weakness what are they called?
Sedimentary rocks are separated by lines of weakness called bedding planes. These planes represent the original horizontal layers in which the sediments were deposited, and they often serve as zones of weakness along which rocks may break or deform.
What is the most important sedimentary rock feature?
rocky
What is the importance of jointing and bedding planes to the underground structure of caverns?
They act as conduits for the ground-waterso putting into contact with the limestone to initiatedissolution of the limestone. Consequently they also guide passage directions and morphologies. At a much later stage they control the nature of collapses in large voids.
Are batholith concordant or discordant?
Batholiths are typically discordant intrusions, meaning they cut across the existing rock layers and do not conform to the bedding planes of the surrounding rocks.
What is the difference between joints and bedding planes?
Bedding planes are found exclusively in sedimentary rock. Joints are more common in igneous rock, but can be found in sedimentary rock as well. Igneous rock can never have bedding planes, but does have pseudo-bedding planes.
What type of rocks are in bedding planes?
Sedimentary rocks are common in bedding planes due to their layering structure created by the accumulation of sediments. These rocks are often easily eroded, which can result in the formation of bedding planes. Stratification and sedimentary structures are typical in rocks found in bedding planes.
How are horizontal bedding planes formed?
Horizontal bedding planes are formed through the deposition of sediment in layers over time. When sediment, such as sand, silt, or clay, accumulates in a body of water or on land, it settles in horizontal layers due to gravity. Over time, these layers can become compacted and cemented together, creating distinct bedding planes that reflect the conditions of deposition. Geological processes, such as tilting or uplifting, can later expose these horizontal beds for observation.
Bedding planes in sedimentary rocks indicate what?
Bedding planes in sedimentary rocks indicate the separate layers or strata in which the sediment has been deposited over time. These planes can provide important information about the environment in which the rock was formed, including factors like sedimentation rate, depositional environment, and past geological events.
What horizontal intrusive igneous body is framed when magma is injected parallel to sedimentary bedding planes?
The horizontal intrusive igneous body formed when magma is injected parallel to sedimentary bedding planes is called a "sill." Sills are typically formed when magma intrudes between layers of sedimentary rock, causing the surrounding rock to be lifted or distorted. They can vary in thickness and are often composed of basalt or other igneous materials.
What are horizontal cracks in rocks called?
They are called bedding planes
What are horizontal cracks in limestone called?
Limestone is formed in layers called Bedding Planes and the vertical cracks are called Joints. The horizontal cracks are not given a specific name - however I am sure someone will want to contradict this
Are bedding planes a feature?
Yes, bedding planes are a geological feature that represents the surfaces separating different layers of sedimentary rock. They indicate changes in sediment deposition, such as shifts in environment or energy conditions. Bedding planes can provide valuable information about the history of sediment accumulation and are important for understanding geological formations and processes.
Which most likely exhibits well defined bedding planes?
gabbro
Whats the difference in graded bedding and cross bedding?
Surfaces between layers of sediments (bedding planes) are usually deposited in horizontal sheets, but cross-bedding is inclined. Graded beds are horizontal and are usually sorted from coarse at the bottom to fine at the top.
What is formed by the intersections of two planes?
Angles are formed by the intersection of two planes.
Sedimentary rocks are separated by a lines of weakness what are they called?
Sedimentary rocks are separated by lines of weakness called bedding planes. These planes represent the original horizontal layers in which the sediments were deposited, and they often serve as zones of weakness along which rocks may break or deform.
