摘要
在地质测量和钻孔钻探中所获得的岩矿层厚度经常不是岩矿层顶底间最小厚度——垂厚,如果已知岩矿层顶一点A和岩矿层底一点B的AB的长度;AB与铅垂线的夹角α;岩矿层的倾角β;AB方位线与岩矿层倾向线的夹角ω≤90°,则可用下式计算岩矿层垂厚——岩矿层真厚度m。计算条件是A、B两点所在顶、底面平行。
The true stratal width or thickness is the shortest distance between two bedded planes, but it is rarely to be found by us. In the artricle the problem is discussed and solved, some correct formulas and an obvious mistake formula are indicated by wang Yichi.
