China's geographical changes, with the passage of time, are full of wonder and magnificence. Hundreds of millions of years ago, there was a magnificent ancient river in this land, which was wider than the Yangtze River today. The river's splendor coincides with the age of the dinosaurs, but its scale eclipses the modern river.
Exploring Ancient Landforms: The Magical Land of China 200 Million Years Ago.
During the Jurassic period, China's landforms resembled paradise. Under the influence of the Indosinian tectonic movement, the basin was uplifted, forming a variety of paleolandforms such as highlands, low mountains and hills, deep-cut river valleys and depressions. Ancient landform highlands such as Yanchi, Dingbian, Jiyuan, etc., are distributed along the river valley, constituting a magnificent scene. And imagine that Zhidan County in Yan'an is actually in He**, and Wuqi County is located on an island in the river, this magnificent landscape is breathtaking.
Magnificent Rivers: A super waterway in ancient China.
During that period, more than one huge river existed, the Yangtze River. Ancient rivers such as Gansu-Shaanxi, Ning-Shaanxi, Meng-Shaanxi, Jin-Shaanxi and Qingxi complement each other, among which the ancient river of Gansu-Shaanxi is the mainstay, and its width can even reach 80 kilometers. These rivers are cut at different depths and widths, resulting in different slopes on both sides of the valley, creating a spectacular topography.
Magical Rocks: The imprint of the ancient river.
This ancient river not only leaves a profound imprint on the topography, but also directly controls the lithology of the strata. In the deep-cut valley intersection, sediments can be up to 130 m thick and are filled with coarse lithological conglomeratesIn the hilly areas, thinner mudstone and siltstone were deposited. These rocks are layered on top of each other, witnessing the miracle of ancient geological changes.
Natural evolution: vicissitudes of life, endless miracles.
The evolution of these natural landscapes illustrates the true meaning of the vicissitudes of life. The uplift of paleolandforms and the changes in sedimentation have changed the contours of China's landforms, shrinking the highlands and widening the river valleys, forming the magnificent geographical landscape of today.
Back in time: a journey to China 200 million years ago.
If you travel back in time to this era, a trip to Xi'an will be a magnificent adventure. There are no trains, automobiles or highways, only vehicles and boats can cross the ancient Ganshan Ancient River, allowing northern Shaanxi and Gansu people to meet.
This is the wonderful history of China's geographical changes, a picture of nature's miraculous workmanship. Even without human presence, the land still shines with endless charm, reminding us of the greatness and infinite wonders of nature.
This essay on the geographical changes in ancient China gives a glimpse of the magic of natural evolution. Through the description of China's landforms 200 million years ago, the author takes readers through time and explores the magnificence of ancient magnificent landscapes.
First of all, the article depicts the magnificence of the ancient landforms. During the Jurassic period, the Indosinian tectonic movement shaped China's landforms, and the basin uplifted to form a variety of landscapes such as highlands, low hills, and deep-cut river valleys. The highland distribution and the confluence of rivers mentioned in the description are stunning. These scenes seem to outline a magnificent picture of nature, making people feel the majesty of nature.
Secondly, the depiction of ancient rivers is also fascinating. The existence of ancient rivers such as Ganshan and Ningshan shows the complexity and grandeur of ancient Chinese water systems. In particular, the spectacular scene of the 80-kilometer-wide Ganshan Ancient River makes people interested in the changes of ancient geology and the magical charm of the river.
The influence of paleogeomorphology on rock sedimentation is also described in detail. The stratigraphic lithology left by ancient rivers is different in different regions, and this geological phenomenon provides valuable clues for the understanding of ancient Chinese geography. These rocks carry information from a bygone era, allowing us to peek into what the ancient earth looked like.
Finally, the article concludes with a thought-provoking note that if modern humans were to travel back in time, travel would be full of adventure and challenges. This assumption makes one wonder about the vast differences between ancient civilizations and modern technology, and the impact of geography on human activity.
Overall, this article is not only shocking to the beauty of ancient geography, but also provokes deep thinking about the evolution of nature and the transformation of the earth. It transports the reader on a magical journey through time and space, showcasing the wonders and wonders of nature.
