Which of the following is a sedimentary structure?

Sedimentary structures include features like bedding, ripple marks, fossil tracks and trails, and mud breaks. … Examples include bedding or stratification, graded bedding, and cross-bedding.

What are sedimentary rock structures?

Sedimentary structures are visible textures or arrangements of sediments within a rock. Geologists use these structures to interpret the processes that made the rock and the environment in which it formed.

What are three types of sedimentary structures?

Three common sedimentary structures that are created by these processes are herringbone cross-stratification, flaser bedding, and interference ripples.

Which of the following is not a sedimentary rock apex?

No, marble cannot be considered as sedimentary rock. It is a metamorphic rock which is metamorphosed limestone, compound of pure calcium carbonate.

What are sedimentary rocks examples?

Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock.

Are fossils sedimentary structures?

Although trace fossils can be considered as biogenic sedimentary structures and are difficult to classify phylogenetically, they are constructed by biological entities and are thus subjected at least to some degree to evolutionary trends.

What is not a type of sedimentary rock?

There is no such thing as a metamorphised sedimentary rock. Any rock that is metamorphised would be called as a metamorphic rock. Geography.

Is a dike a sedimentary structure?

A clastic dike is a seam of sedimentary material that fills an open fracture in and cuts across sedimentary rock strata or layering in other rock types. … Clastic dikes are found in sedimentary basin deposits worldwide.

Is Limestone is a sedimentary rock?

Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.

Which of the following is not the type of rock?

The correct answer is Ox-bow. Ox-bow is not a type of rock.

What is not a metamorphic rock?

The correct answer is Limestone. Limestone is not a Metamorphic rock. … Sedimentary rocks are classified on the basis of the nature of sediments: chemically, mechanically, and organically formed rocks. Sometimes the rocks remain of plants, deceased animals, and contain fossils are found in the deposited material.

How are non sedimentary rocks formed?

How Non-Clastic Sedimentary Rocks are Formed: Formed by chemical precipitation from a concentrated solution in water as salt, gypsum, or limestone. Characteristics: Soft, because they are composed of soft minerals such as halite, gypsum, calcite.

Which are examples of non foliated rocks?

Overview. Nonfoliated metamorphic rocks lack foliated texture because they often lack platy minerals such as micas. They commonly result from contact or regional metamorphism. Examples include marble, quartzite, greenstone, hornfel, and anthracite.

Which of the following is not a characteristic of a mineral?

Answer: The correct answer is option (C) – They are inexhaustible. Minerals occur in different types of rocks.

Which of the following is not a characteristic of metamorphic rock?

Hence, Limestone is not a metamorphic rock.

It is formed when molten rock (magma or lava) cools and solidifies. Igneous rock may form with or without crystallization. It may be intrusive (plutonic) rocks or extrusive (volcanic) rocks. For example, Granite, Basalt, etc.

Which of the following is not a foliated metamorphic rock?

Non-foliated metamorphic rocks do not have a layered or banded appearance. Examples of nonfoliated rocks include: hornfels, marble, novaculite, quartzite, and skarn.

Which is not a foliated metamorphic rock?

Foliated metamorphic rocks such as gneiss, phyllite, schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite and novaculite do not have a layered or banded appearance.

What is non-foliated metamorphic rock?

Non-Foliated Metamorphic Rocks:

Non-foliated metamorphic rocks do not have a platy or sheet-like structure. There are several ways that non-foliated rocks can be produced. Some rocks, such as limestone are made of minerals that are not flat or elongate.
