地质剖面图是按一定比例尺、一定线路、一定方向做的剖面图,地质剖面图能直观地反映出岩层的形态、相互关系和地表的高低起伏。按照高考的要求,同学们在地质剖面图上要能够通过岩层的新老关系、沉积岩中的化石、各种岩层的相互关系确定地层的新老关系和顺序;能够根据岩层的形态和地质年代确定背斜和向斜;能够根据岩层是否断裂并沿断裂面是否错动位移判断断层构造;从地层的相互关系判断地壳运动的性质和特点;通过研究地质剖面图,指导人们找水、找 Geological profile is a certain scale, a certain line, a certain direction profile, geological profile can visually reflect the rock formation, correlation and the ups and downs of the surface. According to the requirements of the college entrance examination, students should be able to determine the relationship between old and new stratigraphy and sequence through the relationship between the old and new strata of the rock strata, the fossils in the sedimentary rock and various rock strata. According to the rock formations and geologic age, Anticline and syncline; to judge the fault structure according to whether the rock is broken and whether the fracture surface is dislocated or not; to judge the nature and characteristics of the crustal movement from the correlation of the strata; to guide the people to look for water by studying the geological section map
