泉是地下水在地表的天然露头。泉水中往往含有较多的矿物质,当这些矿物质从泉水中析出并沉淀下来时,便形成为疏松多孔的泉华。如果说,青藏高原本来是一张平整的大纸,那么正是由于中生代以来的地壳运动,尤其是新构造运动的剧烈揉搓,才使得这张大纸满是皱纹与孔洞。这就造成了该区构造发育,泉眼甚多,无论是古泉华,还是现代泉华都很普遍,并且多沿约基台一金沙江、班公湖一怒江、雅鲁藏布江等深大断裂成带状展布。西藏已发现的泉华,按化学成份可分为钙华、硅华、硫华、
Spring is the natural outcrop of groundwater at the surface. Spring water often contains more minerals, when these minerals are precipitated from the spring water and settle down, it becomes loose porous Qu Hua. If we say that the Qinghai-Tibet Plateau was originally a large, flat piece of paper, it was precisely because of the crustal movement since the Mesozoic, especially the intense rubbing of the neotectonic movement, that this paper was full of wrinkles and holes. This resulted in the tectonic development in this area. There are many springs in the area, both of which are ancient springs and modern springs, and are mostly banded along the Jindaai-Jinsha River, Bangong-Nujiang, Brahmaputra and other deep faults Spread. Quanhua has been found in Tibet, according to chemical composition can be divided into travertine, silicon, sulfur,
