摘    要:目的丰富野外地质填图方法和技术,提高地质填图的水平和图件质量。方法在遥感图像解译与地质填图实践的基础上,利用地质产状与地形变化的关系,在需要内插地质界线点的地段,垂直岩层走向切地形剖面,将剖面旁侧已知界线点的产状沿走向移至剖面中的相应高程处,再过此点延伸倾向线至地形剖面线,交点即为内插地质分界点,最后结合"V"字形法则,过同一地质界线的不同交点,求联地质界线。结果得出了地层产状稳定、走向不变而倾角变化、倾角不变而走向变化及倾角、走向均有变化4种不同的内插地质界线点编联地质界线具体作图方法与步骤,大大丰富和方便了野外填图工作。结论该方法既准确快速又方便可行,保证了地质界线勾绘的质量。

关 键 词:地质填图  地质界线勾绘  剖面法  “V”字形法则  遥感解译

Abstract:Aim To enrich the field methods and techniques,improve the level of geological mapping and the quality of geological maps.Methods On the basis of the interpretation by remote sensing image and the field practice of geological mapping,making use of the relationship between the attitude of rocks and terrain,draw terrain profile in the direction of vertical rock-strike in the needed place of inteposing the geological point,move the known attitude on the geological point beside of the terrain profile to the profile as same elevation as the known geological point along the rock-strike.Extend the terrain profile along the dip direction,the point of intersection is the inserted geological point.Finally,link up the different inserted geological points into geological boundary by the "V" shaped law.Results Four constructive methods were obtained and process in the case that the attitude of rocks is stable,the strike is same,but the angle of inclination is different,the angle of inclination is same,but the strike is different,the strike and the angle of inclination are different.Conclusion The method of using the geological section is fast,accurate and convenient,It can guarantee the quality of linking up geological boundary.
Keywords:geological mapping  linking up geological boundary  the law of geological section  "V" form rule  remote sensing interpretation
