WebAnswer (1 of 2): Rock folding occurs when rocks are compressed together and the layers of rock behave like putty (deform plastically) from the point of view of the observer (this … WebUMass WebNumerous closely spaced fold hinges may produce a lineation in highly deformed rocks. This structure is called a crenulation lineation. Fold axial surfaces: Numerous closely spaced fold axial surfaces define a fabric called called crenulation cleavage, because the axial surfaces may be planes of weakness along which a rock tends to split. iocl haldia refinery

WebWhen a body of rock, especially sedimentary rock, is squeezed from the sides by tectonic forces, it is likely to fracture and/or become faulted if it is cold and brittle, or become folded if it is warm enough to behave in a plastic manner. The nomenclature and geometry of folds are summarized on Figure 12.5.

WebThe type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.

WebRock exposures become progressively younger towards the axis of synclines. 9. Rock layers dip away from the fold axis in anticlines, but dip toward the fold axis in synclines. Plunging Folds. 1. Figure 10.10: A fold can be divided by an imaginary surface called the axial plane. The axial plane divides a fold as symmetrically as possible. WebThere are several ways that non-foliated rocks can be produced. Some rocks, such as limestone are made of minerals that are not flat or elongate. No matter how much pressure you apply, the grains will not align! Another type of metamorphism, contact metamorphism, occurs when hot igneous rock intrudes into some pre-existing rock.
