为配合煤田预测工作,1971年我们对分布于鸡西煤田北部条带的各个中生代砾岩层的砾石岩性组成、砾石的粒度、形态以及砾石的空间排列方位作了观测。测量了七个点748个砾石(图1),并用数理统计的方法进行了分析,获得了反映砾岩组构特征的数量指标。依据这些数量指标结合区域地质情况,对砾岩的形成条件作了初步讨论。不妥之处,欢迎指正。
In line with the prediction of coalfield work, in 1971 we observed the gravel lithology, the gravel size and shape, and the spatial arrangement of gravel in each Mesozoic conglomerate layer distributed in the northern Jixi coalfield. A total of 748 gravels at seven points were measured (Figure 1) and analyzed using mathematical statistics. Quantitative indices reflecting conglomerate structure characteristics were obtained. Based on these quantitative indexes combined with the regional geological conditions, the formation conditions of conglomerates were preliminarily discussed. Inappropriate place, welcome to correct.
