江西省三大世界地质公园研学旅行地学资源及其成因综述

A Review on Geo-study Tour Resources and Interpretation in the Three Global Geo-parks of Jiangxi

江西省拥有庐山、三清山和龙虎山三个世界地质公园,就犹如各具特色的天然地学博物馆,地质遗迹和景观十分丰富。青少年在研学旅行中不仅要欣赏大自然鬼斧神工,也要去读懂穿越时空的地球故事。根据这三大地质公园中经典的地学研学旅行线路,阐述其形成的地质背景、成因和所包含的地质意义。庐山是一座崛起于平地的地垒式断块山,东临鄱阳湖,北临长江,构成了一副壮美的山江湖画卷。庐山以典型的中国大陆东部低纬度山地第四纪冰川遗迹地貌景观著称,是中国第四纪冰川地质学的诞生地。三清山地区涵盖了自中元古代至第四纪10多亿年几乎连续的地层,经历了多次重大地质事件和“三海三陆”沧海桑田的演化。中生代早白垩世三清山花岗岩岩基侵位于地下约6km处,在独特的“隆上隆”构造背景下岩体多次抬升,才形成了现今以尖峰陡坡为特色的幼壮年期花岗岩峰林地貌。龙虎山地区在中生代白垩纪沉积了以河口组和塘边组为代表的(近)水平的厚层红色岩系,主要受流水侵蚀及崩塌后退等外动力地质作用的塑造,形成顶平,坡陡,麓缓的典型壮年晚期丹霞地貌景观。

study tour was adopted as a compulsory course in primary and middle schools in order to improve the students'comprehensive quality in November 2016.Jiangxi owns three global geoparks:Mt.Lushan,Mt.Sanqingshan and Mt.Longhushan.They are natural distinctive geological museums,with abundant geological relics and landscapes.Teenagers will be astonished by the unbelievable workmanship of nature,and meanwhile they also need to understand the earth's story beyond time and space.It deserves"travelling thousands of miles for knowledge and reading thousands of books in tour.The paper will review their geological backgrounds,interpretations and implications based on the classic geo-study tour routes in three global geo-parks of Jiangxi province.
