some minerals are mica, fledspar, and rocks are marble, shale ,slate,granite etc.
Not in the amounts you would expect from a metal, but surprisingly yes. This is mainly due to the water in the pores, whose conductivity is increased by ions from the minerals in the shale.
Rocks are aggregates of minerals,thus there is no rock without minerals. Q.E.D
Never say never, but it's mica.
The Shale is not a metamorphic rock it is a sedimentary rock.
no
Shale typically contains minerals such as clay minerals (like kaolinite, illite, and smectite), quartz, calcite, feldspar, and pyrite. The exact mineral composition can vary based on the specific shale formation.
Shale rock is primarily composed of clay minerals and small particles of other minerals like quartz and calcite. These minerals are compacted together over time to form the distinct layers of shale rock.
Shale is not an element. Shale is a type of sedimentary rock composed of clay-sized particles that have been compacted over time. It is made up of various minerals such as quartz, feldspar, and clay minerals.
== Shale is a sedimentary rock, comprised of lithified mud and clay minerals.
Shale turns into slate through a process called metamorphism, where heat and pressure transform the shale's minerals into new minerals like mica and chlorite. This process also causes the shale's original clay minerals to recrystallize, making it more compact and giving it a foliated texture characteristic of slate.
Shale forms from the compaction of mud or clay sediments, often in quiet water environments such as lakes or deep ocean basins. These sediments are typically rich in fine particles such as clay minerals and organic matter, which bond together to create the layered structure of shale.
Shale can range in age from hundreds of millions to billions of years old. The age of a specific shale deposit can be determined by dating the fossils contained within it or using radiometric dating techniques on the minerals present in the rock.
Minerals could include clays, feldspars, quartz, micas, and pyrite
The chemical formula of shale is variable, as it is a sedimentary rock composed mainly of clay minerals, quartz, and other minerals. The general formula can be written as (Al,Si)3O10(OH)2, representing the presence of aluminosilicate clay minerals in shale.
Identifying minerals in shale and slate can be difficult because these rocks typically have fine-grained textures that make individual mineral crystals hard to see with the naked eye. Additionally, shale and slate often contain a mix of minerals like clay minerals, quartz, and micas that can be challenging to distinguish without specialized equipment like a microscope or chemical analysis. The high degree of metamorphism in shale and slate can further alter the mineral composition, making identification even more complex.
Shale can sometimes contain magnetic minerals, such as magnetite or hematite, which can make it slightly magnetic. However, the magnetic properties of shale can vary depending on the specific mineral content and geological conditions.
