我们在野外观察泰山地区的变質岩时,顺便也攀登了具有六百阶梯、高153米的泰山山顶,由此北望,可以看到兩座迥然不同的山峯,那就是圓頂的后石山嵨及其对面的陡峭峻嶺。这些山峯是由粒度甚小、直徑約1.5毫米的含雲母很少的泰山系混合花崗岩所組成(图1,见封二)。此花崗岩未受強烈的近代风化作用。在陡度不大的平山頂上,可以看到一层細粒浮土盖层,另在山溝中形成被切割很深的V形夾谷。
When we were observing the metamorphic rocks in the Taishan area in the field, we also climbed the Taishan Peak with six hundred steps and 153 meters high by the way. From this north, we can see two very different peaks, that is,嵨 and steep mountains opposite. These peaks are composed of Taishan mixed granites with very small particle size and about 1.5 mm in diameter, with little mica (Fig. 1, cap. II). This granite is not strongly modern weathering. In the steep slope of the top of Ping Shan, you can see a layer of fine floating earth cover, the other in the formation of the valley was cut deep V-shaped valley.
