Which of the following describes lineation?

A) May be due to elongated mineral crystals that grow in linear orientation.
B) Stretched-out mineral crystals may show lineation.
C) Can form under ductile shearing.
D) All of these describe lineation.

Lineation

A linear feature within rock, such as grain elongation or mineral stretching, that indicates flow or movement directions during formation.

Elongated Mineral

A mineral shape characterized by being significantly longer in one direction than in the others, common in some types of crystals.

Ductile Shearing

Ductile shearing is the deformation of materials through stretching or shearing, allowing them to bend and shape without breaking, often in geological contexts.

  • Pinpoint and characterize the essential features of metamorphic rocks, with an emphasis on foliation and nonfoliation.
