If a metamorphic rock has grains arranged in parallel layers or bands what is the rock probably displaying?
Generically it is displaying a metamorphic fabric, specifically a schistosity. If the fabric is well developed it could also be displaying planes of cleavage.
Do protostomes and deuterostomes differ in their manner of cell cleavage during embryonic?
Yes
What is schistosity in rock?
Schistosity refers to a particular rock texture found in certain metamorphic rocks, that is a reaction to increases in directionally applied stress and temperature. Schistosity is present where the texture of the rock exhibits a platy, layered appearance, with visible crystals of micas and other minerals, oriented in the same direction. The mineral crystals have become aligned perpendicularly to the direction of the applied stress.
What is silvers cleavage?
Silvers Cleavage Is Silver Doesn't Split .
Is slate the rock that can be split into thin layers?
Yes. It has a property known as slaty cleavage which occurs due to the alignment of clay minerals when clay rich rocks such as silt, clay and mud stones are compressed by tectonic activity. This aligned allows the rock to be slit parallel to the clay mineral grains.
What is The cleavage of a shale rock?
Schist has slaty cleavage, also called crenulations ( tiny folds).
What is surface of a break in a section of rocks?
This could be a beading plane, a plane of cleavage or schistosity, or a fault plane.
How does the origin of slaty cleavage differ from the origin of fissility in shale?
Slaty cleavage is a result of stress and strain during the metamorphism process where the minerals that make up the slate become deformed and or re-crystallise with an orientation normal to the principle stress field. The fissile nature of shale is a result of the preferential alignment of clay minerals during the formation of the rock. This is because clay minerals are plate like and so form horizontal layers much like you would get if you stacked playing cards.
How does the cleAvage of graphite differ from that of mica?
Cleavage refers to the tendency of a mineral to break along flat surfaces. Graphite and mica have the same type of cleavage, which is a perfect basal cleavage.
If a metamorphic rock has grains arranged in parallel layers or bands what is the rock probably displaying?
Generically it is displaying a metamorphic fabric, specifically a schistosity. If the fabric is well developed it could also be displaying planes of cleavage.
What does schistosity tell geologists?
Schistosity tells about the transportation, deposition and compaction of sediments in terms of shape, size etc
