政和县石屯公社的富竹庄—马面山村一带,所出露的老变质岩系比较连续,岩类也较多,是一个较好的研究地段。过去曾不只一个单位在这里测过地层剖面。省区测队(1972)将其层位划为前震旦纪“建瓯群”的一个部份,图1是原区测报告中所附的一个实测剖面。通过实地检验,发觉他们当时认为片理与层理一致,并按片理的产状来制图。图上只反映了变质期发生的褶皱的轴面片理(详后)形成后所发生的一期宽缓的迭加褶皱的一翼。而且地
In the area of Fuzhuzhuang-Mamianshan Village in Shitun commune, Zhenghe County, the old metamorphic rocks exposed are relatively continuous and there are more rock types, which is a good study area. In the past, more than one unit had measured the stratigraphic profile here. The Provincial Test Team (1972) zoned its horizon to a part of the Pre-Sinian “Jianou Group”. Figure 1 shows a measured profile attached to the original test report. Through the field test, they found that they thought the film was consistent with the layering and made the picture according to the filming. The figure only reflects the occurrence of the degenerate folds of the surface of the filming (in detail) after the formation of a period of occurrence of a superimposed fold wing. And also
