In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle ) measured downward from horizontal. [ 1 ]
A dip slope is a topographic (geomorphic) surface which slopes in the same direction, and often by the same amount, as the true dip or apparent dip of the underlying strata. [ 1 ] [ 2 ] A dip slope consists of the upper surface of a resistant layer of rock, often called caprock , that is commonly only slightly lowered and reduced in steepness ...
Structural geology is the study of the three-dimensional distribution of rock units ... The inclination of a planar structure in geology is measured by strike and dip ...
Dip (geology) (strike and dip), the orientation or attitude of a geologic feature; Dip slope, a slope parallel to the dip in geology; Dip circle, used to measure the angle between magnetic dip and the horizon; Magnetic dip, the angle made with the horizontal at any point by the Earth's magnetic field; Horizon dip, the angle below horizontal for ...
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
In geology, a fault is a planar ... Dip-slip faults can be either normal ("extensional") or reverse. The terminology of "normal" and "reverse" comes from coal mining ...
In geology, the term is more specifically applied to a ridge where a harder sedimentary rock overlies a softer layer, the whole being tilted somewhat from the horizontal. This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata , called caprock .
Dip is defined as the angle of the fault relative to the surface of the earth, which indicates the plane on which slip will occur. Lastly, in any non-vertical fault, the block above the fault is called the hanging wall, while the blockbelow the fault is called the footwall. [4] Normal and reverse dip-slip faults with labeled hanging wall and ...
