我们可以确定当蘸了罢工?相反的呢?

在任何地质平面,罢工给一条线的方向由水平面和地质平面的交点。和显示地质平面的方向。在学习的时候,我知道罢工是垂直于倾斜。但是当我试图确定浸罢工,我不能这样做。但当我可以决定罢工时下降。我们怎么确定浸渍如果知道罢工?

罢工和下降的一种方式描述三维空间中的一个平面的方向。罢工是飞机的交叉角水平表面的罢工水平面是未定义的。就像两条相交线定义一个点,两个相交平面定义一条线。您可以定义一个垂直于线的罢工,这定义的方向倾斜。如果你想象一个垂直平面相交的水平面将沿着这条直线相交原始地质表面沿着另一条线。倾斜的方向之间的角度和地质表面倾角,或者只是下降。一般来说,浸总是测量角度从水平。如果有人给你一个罢工和倾斜,你仍然需要一个信息来确定飞机的方向。那是因为你需要知道如果飞机倾斜你的左或右,如果你正在寻找的方向。一些约定指定倾斜的方向(例如东),但我更喜欢使用一个约定,你定义攻击方向,这样你蘸右侧(右手法则)如果罢工是一条线,点,例如10度(北东部)和190度(南部以西10度)和倾斜30度到190度西你会说罢工,倾斜30度。 The dip is the maximum angle that can be measured between your geologic plane and the horizontal. Sometimes it is hard to tell if your are measuring the angle exactly down-dip and the value of that apparent dip will be less than the true dip. Another way to describe the orientation of the same geologic plane is use the bearing and plunge (also termed plunge and azimuth). Go back to the vertical plane perpendicular to strike and its intersection with the geologic plane. Imagine looking along the line where that plane intersects the horizontal and facing down dip. That direction is the bearing (the strike plus 90 degrees if you are using the right-hand rule). The plunge is just the dip angle. The reason it is called something different is that you can use the same terminology to describe any linear feature such as the line where a bed intersects a fault. I suspect that when you say, "dip shows the orientation of the geological plane" you mean both the dip angle (the plunge) *and* the bearing of the dip line. So in actuality you are still using two values with the bearing being 90 degrees from the strike. The reason you can't just use the strike is that that does not give you the angle value. There is another way to define the orientation of a plane by defining the vector that is normal to the plane. That line forms an angle of 90 degrees with the line of dip. The convention in structural geology is to use the vector where the perpendicular to the plane points downward, not up in the air. The bearing and plunge of that vector is used to plot features on stereo-nets - a handy way to reduce the orientation of a number of planes to a number of points.
