摘要: 介绍了用微机实现圆弧法绘制地层剖面图的主要步骤和原理，在圆弧法中引进了扇区的概念和确定扇区的方法，扩展了圆弧法绘制地层剖面图的适用范围。同时，给出了处理剖面上的断层和岩脉、组成剖面扇区、连接岩层线、处理变质岩的波浪线和特殊线型、确定矿物花纹的位置、方向和大小等问题的具体方法和步骤Abstract: This paper introduces the major steps and principle of drawing the measured stratigraphic section by using the circular arc method with a microcomputer.The concept of the sector is introduced in the method;thus the method can be applied to more complex stratigraphic sections.Detailed steps are given about dealing with the faults and dikes in a section linking stratal lines in several sectors,drawing wavy lines and special line types of metamorphic rocks ,determining the position,scale and direction of mineral patterns and symbols.
