构造地质学“V”字型法则教学中的简明图示法

【摘要】 “V”字型法则在地形地质图中用来判断地层或断层的产状，在地质填图和航空照片、卫星照片解译工作中也有着广泛的应用。用简明图示法，让学生学会用简单的几根曲线，画出岩层或断层与地面的空间关系，进而得出地层或断层出露线与地形等高线在水平投影面上的平面关系，可提高学生的空间想象力，学会推演出“V”字型法则，真正理解并掌握，变成自己的一种技能。更多还原

【Abstract】 The "V" rule is used to judge the occurrence of strata or faults in topographic and geological maps, and it is also widely used in geological mapping and interpretation of aerial photos and satellite photos. With concise graphic method,students can learn to draw the spatial relationship between rock strata or faults and the ground with simple curves, and then get the planar relationship between the exposed lines of rock strata or faults and topographic contours on the horizontal projection plane(topographic and geological map), which can improve students’ spatial imagination, learn to deduce the "V" rule, truly understand and master it, and become their own skill.更多还原
