青藏高原是否曾经为统一的大冰盖,在地学界一直存在较大争议。上世纪80年代,科学家们在对横断山的考察中,意外地在稻城县与理塘县之间的海子山发现大量的古冰川遗迹,让这一话题重新变得活跃而有趣。它至少证明,在青藏高原的东南部,第四纪的确发育过一个大冰帽——稻城古冰帽。探寻稻城古冰帽是一件既兴奋又艰苦的工作,越野车西出成都平原不久,便被茫茫群山卷入其中。穿过二郎山,笼罩在四川盆地上方的雾霭一扫而光,高原的天空碧莹如洗。越往深处,汽车就象进入了山的海洋,折
Whether the Qinghai-Tibet Plateau was a unified large ice sheet has always been the subject of great controversy in the geoscience community. In the 1980s, scientists unexpectedly found a large number of ancient glacial relics in Haizi Mountain between Daocheng County and Litang County, making the topic an active and interesting one again. It at least proves that in the southeastern part of the Qinghai-Tibet Plateau, a large ice cap, the Ancient City Ice Cap, has indeed developed. Exploration of Daocheng inagi ice cap is an exciting and hard work, off-road vehicles west of Chengdu Plain, it was surrounded by vast mountains. Pass Erlang Mountain, enveloped in the mist above the Sichuan Basin swept away, the sky blue sky Yingying wash. The deeper into the car like a mountain into the ocean, off
