1980年作者在西藏林周、申扎地区发现了石炭纪冰海相沉积地层。林宝玉在《地质论评》1981年第27卷第 4期曾作过报道。但该文称其为“与冰水有关的沉积”,时代属“中石炭世永珠群上组”。作者通过详细室内研究,认为该区冰海相地层的形成,不是“与冰水有关的沉积”,而是属冰川-海洋相(简称冰海相)复合成因的产物。同时申扎地区冰海相地层不但在中石炭世有广泛分布,在下石炭统、上石炭统也有发现。
In 1980, the author discovered the Carboniferous ice marine sedimentary formations in the Linzhou and Xizha areas of Tibet. Lin Baoyu in the “Geological Review” in 1981 twenty-seventh No. 4 has made reports. However, the paper calls it “sediments related to ice-water” and belongs to the “Upper Carbon Formation of the Group”. Through detailed studies in the interior, the author believes that the formation of the ice-sea facies in this area is not a product of ice and water-related sedimentation but rather a complex genesis of the glacier-ocean phase (ice-sea phase). At the same time, the ice-sea strata in the Xinsha area are not only widely distributed in the Middle Carboniferous, but also found in the Lower Carboniferous and Upper Carboniferous.
