岩层真厚度计算公式的图解分析

Graphic Analysis of Calculation Formula for True Thickness of Rock Stratum

岩层真厚度计算是野外地质填图中制作综合地层柱状图重要的一环,也是教学的重点和难点。由于岩层真厚度的计算公式过于繁杂,学生往往死记硬背公式而不理解其所代表的地质含义,导致在野外处理实际问题时无法根据实际情况选择合适的公式进行计算。本文通过空间思维,将岩层真厚度的计算公式与实际地质现象建立联系,建立起公式的三维空间图解。该方法使抽象的公式转换为了形象的图形,利于理解,便于记忆,在教学实践中取得了良好的效果。

The calculation of true thickness of strata is not only an important part of making comprehensive stratigraphic histogram in field geological mapping,but also an important and difficult point in teaching.Because the calculation formula of the true thickness of rock strata is too complicated,students can only memorize the formula by rote,but do not understand the geological meaning it represents,which leads to the fact that the treatment of the actual phenomenon in the field cannot be adapted according to the actual situation and choose the appropriate formula for calculation.In this paper,through spatial thinking,the calculation formula of the true thickness of rock strata is connected with the actual geological phenomenon,and the three-dimensional diagram of the formula is established.This method makes the abstract formula into image graphics,which is easy to understand and remember,and has achieved good results in teaching practice.
