Science / Geology / Foliation: The planar or layered characteristics of metamorphic rocks that are evidence of the pressures and/or temperatures to which the rock was exposed. These can be structural such as cleavage, textural such as mineral grain flattening or elongation, or compositional such as mineral segregation banding.
Science / Geology / Exfoliation: A physical weathering process in which sheets of rock are fractured and detached from an outcrop. MORE
Health / Massage / Bindi: This bodywork combines marine algae exfoliation, herbal treatment, and light massage. MORE
Science / Geology / Schist: A metamorphic rock containing abundant particles of mica, characterized by strong foliation, and originating from a metamorphism in which directed pressure plays a significant role. Picture of Schist. MORE
Science / Geology / Hornfels: A high-temperature, low-pressure metamorphic rock of uniform grain size showing no foliation. Usually formed by contact metamorphism. MORE
Science / Geology / Massive Rock: A rock that is little or not at all broken by joints, cracks, foliation, or bedding, tending to present a homogeneous appearance. MORE
