山东省沉积岩建造组合划分

Division of Construction Combinations in Sedimentary Rocks in Shandong Province

摘要:

为编制1∶50万山东省大地构造相工作底图（沉积岩区）提供依据，按照沉积岩建造组合划分原则和大地构造相研究的有关要求，划分了山东省沉积岩区大地构造相和沉积岩建造组合，将山东省沉积岩区大地构造相划分为2个相系（Ⅰ级）、3个大相（Ⅱ级）、15个相（Ⅲ级）、27个亚相（Ⅳ级）及 40个建造组合（Ⅴ级），并简要介绍了主要沉积岩建造组合基本特征。

Abstract:

In order to provide some basis for making "Tectonic Phase Base Map (sedimentary area) in Shandong Province with the Scale of 1∶ 500000", compilation of sedimentary rocks in "Tectonic Phase Map in Shandong Province with the Scale of 1∶ 500000", compilation of sedimentary rocks in "Specification of Making Tectonic Phase Map in Shandong Province with the Scale of 1∶ 500000", according to division principle of construction combinations in sedimentary rocks and relative requirements of tectonic phase study, construction combinations in sedimentary rocks and tectonic phases in sedimentary areas in Shandong Province have been divided. Tectonic phases of sedimentary rocks in Shandong province can be divided into two phase systems (Ⅰgrade), 3 large phases (Ⅱ grade), 15 phases (Ⅲ grade), 27 subphases (Ⅳ grade) and 40 construction combinations (Ⅴ grade). Basic characteristics of main construction combinations of sedimentary rocks have been introduced briefly.
