陕西铜川陈炉石地质成因浅析及保护开发建议

Application and Protection Suggestion and Geological Genesis Analyses of Chenlu Stone in Tongchuan, Shaanxi Province

陈炉石产于陈炉镇东山一带,赋存于上奥陶统赵老峪组上段,其岩性为内碎屑灰岩。通过对陈炉石的分布层位、产出特征、盖层条件等综合分析研究,认为沉积层理、结核和生物碎屑、化学成因以及变形构造等是形成陈炉石奇异纹理图案的重要原因,差异风化使陈炉石纹理从层理中显现出来,构成了高浮雕及凹洼等独特结构。目前陈炉石资源滥采乱挖现象严重,破坏了地质环境及资源,如何在开发中保护,在保护中开发是亟待解决的问题。

Chenlu Stone produced in Dongshan of Chenlu town, occurs in ordovician Zhaolaoyu formation, its lithology is intraclast limestones. After the comprehensive analysis and research of distribution of strata, output characteristics and caprock conditions, it holds that tuberculosis and bioclastic deposits, chemical formation and deformation structure is an important factor to form the singular texture pattern, differential weathering make texture emerge from the bedding, forming the unique structure of high relief and calices. Currently logging dig has seriously destroyed geological environment and resource, how to exploit in protection is a problem to be solved.
