GENERAL GEOLOGY

Detailed explanation-1: -(Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.) Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned.

Detailed explanation-2: -Foliated rocks are defined by the parallel alignment of mineral grains that are mostly thin and planar such as micas or in some cases hornblende. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term ‘folia’, like a leaf, for foliation.

Detailed explanation-3: -foliation, planar arrangement of structural or textural features in any rock type but particularly that resulting from the alignment of constituent mineral grains of a metamorphic rock of the regional variety along straight or wavy planes.

Detailed explanation-4: -Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer can be as thin as a sheet of paper, or over a meter in thickness. The word comes from the Latin folium, meaning “leaf", and refers to the sheet-like planar structure.

Detailed explanation-5: -Foliation describes a metamorphic rock whose minerals are aligned in layers. These rock minerals look like stripes or bands that are arranged in parallel layers. Extreme pressure causes the minerals to form these layers.
