天目山第四纪冰川遗迹的存在,卓越的已故地质学家李四光同志在1934年即已提出。解放后,虽有许多单位做过很多工作,但对天目山有无冰川遗迹的存在,以及有几次冰期等问题意见仍然有分歧。1973年春,我们在1964年景存义、邱淑彰两同志调查的基础上,又作了重点考察,结果在天目山北部孝丰西南下汤附近,又发现了冰川纹泥。纹泥层产地在西苕溪谷地高约30米左右的基座阶地上(图1),距天目山深溪坞坞口直线距离15公里。但无具体地点和描述。我们在下汤附近所见的纹泥,夹于两层泥 The existence of the Quaternary glacier relics of the Tianmu Mountain, made by the late deceased geologist Li Siguang, was proposed in 1934. After the liberation, although many units have done a lot of work, there are still differences on the existence of glacier relics in Tianmu Mountain and on several glacial issues.

As a result, we found glacial grain mud in the vicinity of Xiaofeng Southwest Xiaotang in northern Tianmu Mountain.

But no specific place and description. The mud we saw near the soup was covered in two layers of mud
