摘要
野外实习是地质学本科教学不可缺少的重要环节,也是课堂理论教学的补充和延伸。大学三年级的野外教学实习是在学生基本完成了专业课程学习的基础上进行的,着眼于创新思维的启发和科研方法的训练,帮助学生从理论学习向科学研究顺利过渡,是培养地质学专业学生成才的关键课程。文章重点以西北大学地质学系《秦岭造山带—鄂尔多斯盆地野外实践》课程之“造山带构造演化”为例,以板块构造理论为指导,通过考察研究典型路线剖面上保存的古洋壳残片(蛇绿岩)、俯冲—碰撞过程的岩浆、变质、沉积记录,培养学生重建造山带构造演化过程的思路和方法。
Field practice is an indispensable part of geology for the undergraduate students,and it is also a supplement and extension of indoor theory teaching.The juniors have completed their study of major courses after three years,thus the field practice course is designed to inspire and train their innovative thinking and scientific research methods.The“Qinling Orogenic Belt-Ordos Basin Field Excursion”course for senior undergraduates has been set up by the Department of Geology,Northwest University,aiming to helps the students to smoothly transform from study to research.For example,several typical cross-sections crossing the Qinling orogenic belt preserve perfect geological records from subduction to collision,including the ophiolites(remnants of ancient oceanic crust),arc-related volcanic rocks,sedimentary successions,subduction-collisional magmatic and metamorphic rocks.In this paper,we will focus on training the students to reconstruct the tectonic evolution process of the Qinling orogenic belt according to the detailed field investigation on the ophiolitic mélange,deformation,magmatic,metamorphic,and sedimentary records.
