在汇聚群山,发源众水,被称为“世界屋脊”、“离太阳最近的地方”的青藏高原的东南部,有一条波涛汹涌、气势磅礴的大河——雅鲁藏布江。被世界地质学界公认最复杂的地质构造带即北纬29°30′～30°30′,东经94°30′～95°30′之间的高山深谷地区,就是指雅鲁藏布江的大拐弯处。这里雪峰林立、大江汇集、峡谷纵横、温泉广布。科学家通过徒步穿越大峡谷实地测量得知,大峡谷深度为6009米,长度超过500公里,确实可以当之无愧地称为世界之最。科学研究表明,大拐弯地区地壳板块挤压强烈、地应力特别集中、基岩比较破碎、地貌景观奇特、气候类型
In the southeastern part of the Qinghai-Tibet Plateau that brings together the mountains and streams of water, known as the “Roof of the World,” and “the place closest to the sun,” there is a steep and magnificent river, the Brahmaputra. The most complex geotectonic zone recognized by the world geology community, ie, the valley between 29 ° 30 ’and 30 ° 30’N and the valley between 94 ° 30’ and 95 ° 30’E refers to the corner of the Great Brahmaputra. Here snow-lined, the river pool, canyon aspect, wide hot springs. Scientists walk through the Grand Canyon field measurements that the Grand Canyon depth of 6009 meters, more than 500 kilometers in length, can indeed deservedly called the best in the world. Scientific research shows that the crustal plate in the area of the Great Bend is strongly crushed, the geostress is particularly concentrated, the bedrock is relatively broken, the geomorphic landscape is unique, the climate type
