 Spanish term or phrase: "Rumbo" y "manteo" Mining: the sentence reads. Secuencia de rocas con "rumbo" norte-sur y "manteo" este. I'm confused between "strike", "dip" and "trend". Which is which?

 strike / dip Explanation:rumbo = strike (Robb's diccioanrio para ingenieros) manteo = dip Please see diagram in 1st ref. (below is a part of the text) Planes can be defined in space by their inclination or dip and their strike, the bearing of the line of intersection of the plane and a horizontal surface. Notice that the bearing of the projection of the dip on a horizontal surface is in a direction at right angles to the strike. This is called the dip direction. strike = the compass direction of a horizontal line on an inclined plane. dip = The angle of inclination of a planar feature measured from a horizontal datum. The true dip is always mesured in a vertical plane perpendicular to the strike of the plane of either bedding or cleavage. The angle of dip measured in any plane not perpendicular to the strike is an apparent dip and will always be less than the true dip Oxford Earth Sciences dictionary--------------------------------------------------Note added at 29 mins (2003-11-07 18:41:38 GMT)--------------------------------------------------Trend = the azimuth of a geologic feature, commonly of a fold axis, and written as a compass bearing. azimuth = the angle made by a line on the surface of the Earth with magnetic meridian.

rumbo y manteo

Explanation:
Rumbo is heading or the horizontal line of a plane. Manteo (dip) is the angle between the plane and the horizontal plane. The manteo or dip of a horizontal plane is 0 degree and the dip of a vertical plane is 90 degrees.

Series of rocks with a north-south heading and an eastern dip.

Please see the excellent reference below on inclinations and dips in mining.

Explanation:
rumbo = strike (Robb's diccioanrio para ingenieros)
manteo = dip

Please see diagram in 1st ref. (below is a part of the text)

Planes can be defined in space by their inclination or dip and their strike, the bearing of the line of intersection of the plane and a horizontal surface. Notice that the bearing of the projection of the dip on a horizontal surface is in a direction at right angles to the strike. This is called the dip direction.

strike = the compass direction of a horizontal line on an inclined plane.

dip = The angle of inclination of a planar feature measured from a horizontal datum. The true dip is always mesured in a vertical plane perpendicular to the strike of the plane of either bedding or cleavage. The angle of dip measured in any plane not perpendicular to the strike is an apparent dip and will always be less than the true dip

strike:
The geographic alignment of any horizontal line on a planar surface.
dip:
The angle of slope at right angles to strike (the maximum slope of the surface)

strike and dip

Explanation:
Segun lo que te pude investigar esta es mi conclusión:
dip-manteo
strike-rumbo

"dip -- The angle that a bedding plane or fault makes with the horizontal when measured perpendicular to the strike of the bedding plane or fault."

"fault -- A fracture or zone of fractures in rocks of mappable size along which there has been displacement of one side relative to the other."

"strike -- The direction or trend of a bedding plane or fault, as it intersects the horizontal"

--------------------------------------------------------------------
"El manteo o buzamiento (ingl. dip) mide el angulo entre el plano y el plano horizontal."

"rumbo-es la linea horizontal de un plano y marca hacía dos direcciones opuestos. Planos horizontales entonces no tienen un rumbo ( o mejor una cantidad infinita de rumbos). "

no "heading" porque las rocas no se mueven
