This dataset contains soil heavy metal concentration data from 25 key mining areas in western China, including 17 metal mining areas and 8 non-metal mining areas. The 17 metal mining areas are Bayan Obo Iron Mining Area (Inner Mongolia Autonomous Region), Luobasa Chromite Mining Area (Tibet Autonomous Region), Daxin County Manganese Mining Area (Guangxi Zhuang Autonomous Region), Panzhihua Vanadium-Titanium Magnetite Mining Area (Sichuan Province), Yulong Copper Mining Area (Tibet Autonomous Region), Yawan Antimony Mining Area (Gansu Province), Targou Tungsten Mining Area (Gansu Province), Nandan Tin Mining Area (Guangxi Zhuang Autonomous Region), Jinduicheng Molybdenum Mining Area (Shaanxi Province), Xitieshan Lead-Zinc Mining Area (Qinghai Province), Pingguo Aluminum Mining Area (Guangxi Zhuang Autonomous Region), Hami Gold Mining Area (Xinjiang Uygur Autonomous Region), Dongbeizhai Gold Mining Area (Sichuan Province), Yindongzi Silver Mining Area (Shaanxi Province), Jinchuan Platinum Mining Area (Gansu Province), Bayan Obo Rare Earth Mining Area (Inner Mongolia Autonomous Region), and Mianning Rare Earth Mining Area (Sichuan Province). The 8 non-metal mining areas are Shannan Limestone Mining Area (Tibet Autonomous Region), Mendanxia Limestone Mining Area (Qinghai Province), Darhan Muminggan United Banner Mining Area (Inner Mongolia Autonomous Region), Sumuchal Fluorite Mining Area (Inner Mongolia Autonomous Region), Mangyan Asbestos Mining Area (Qinghai Province), Xinkang Asbestos Mining Area (Sichuan Province), Yulin Kaolin Mining Area (Shaanxi Province), and Zhunge'er Kaolin Mining Area (Inner Mongolia Autonomous Region). This dataset is intended to quantify soil heavy metal contents and assess land pollution levels, and includes concentration data of eight soil heavy metals: Cu, Zn, Pb, Cd, Cr, Ni, Hg, and As. All data were measured strictly in accordance with Chinese national standards or well-established domestic and international experimental methods, ensuring the reliability of the dataset quality.
