地球化学区划,是在基础地质研究比较深入的基础上,对地区性地球化学条件和元素性、数、状分布规律进行客观反映、分类的一项工作。这项工作结果,对资源潜力评价、地区性农、林业发展、环境保护、生态系统研究等都有实际指导意义。四川地质构造复杂。川中盆地区、川东褶皱带及川西北高原隆起区、川西南康滇地轴区,其地质特征明显不同,地史发展各异。各区岩浆活动、褶皱断裂活动、沉积岩分布及新
Geochemical zoning is a work that objectively reflects and classifies the regional geochemical conditions and the distribution of elements, numbers and shapes on the basis of comparatively thorough researches on basic geology. The result of this work has practical guidance on the evaluation of potential resources, regional agriculture, forestry development, environmental protection and ecosystem research. Sichuan geological complex. Sichuan Basin Basin, the eastern Sichuan fold belt and the uplift of the northwestern Sichuan Plateau, and the axis of the southwest Kangdian of Sichuan Province. Their geological characteristics are obviously different, and the development history of geography varies. The magmatism, folding and faulting activities, the distribution of sedimentary rocks and new zones in each area
