What is rake in geography?
What is rake in geography?
In structural geology, rake (or pitch) is formally defined as “the angle between a line [or a feature] and the strike line of the plane in which it is found”, measured on the plane. The three-dimensional orientation of a line can be described with just a plunge and trend.
What is the difference between pitch and rake?
rake is more confortable for computer programs, while pitch is easilly measured in the field. They are synonymous. In structural geology “pitch” is the new term for “rake”. Rake (r) is the clockwise angle of the slip vectors from the azimuth of the fault plane and it is measured on a fault plane.
What is earthquake rake?
Rake – the direction the hanging wall moves during rupture, measured relative to the fault strike (between -180 and 180 decimal degrees).
What is vertical and horizontal throw in geology?
horizontal-throw = horizontal component of net-slip. f. heave = stratigraphic heave = apparent horizontal component of the net-slip. Vertical throw, which is the vertical component of net-slip, is different for dipping strata than stratigraphic throw, which is the vertical offset of faulted strata.
What is rake in a fault?
How many is a rake?
Rake is the scaled commission fee taken by a cardroom operating a poker game. It is generally 2.5% to 10% of the pot in each poker hand, up to a predetermined maximum amount.
What is pitch and plunge?
Plunge is the vertical angle between the horizontal plane and the axis or line of maximum elongation of a feature. Plunge is measured along the axis of a fold, whereas dip is measured along the limbs. Pitch is the angle between the axis of the…
What is trend and plunge in geology?
explanation- The trend measures the orientation of a linear feature. The trend is measured in the down plunge direction of the line in the horizontal plane. PLUNGE: definition- The angle between a line and the horizontal datum plane. explanation- The plunge measures the angle of a linear feature.
What is heave throw?
In measuring the horizontal or vertical separation, the throw of the fault is the vertical component of the separation and the heave of the fault is the horizontal component, as in “Throw up and heave out”.
How do you find heave and throw?
The direction and magnitude of heave and throw can be measured only by finding common intersection points on either side of the fault. In practice, it is usually possible to find only the slip direction of faults, and an approximation of the heave and throw vector.
What is rake value?
Rake is the scaled commission fee taken by a cardroom operating a poker game. It is generally 2.5% to 10% of the pot in each poker hand, up to a predetermined maximum amount. There are also other non-percentage ways for a casino to take the rake.
