 China was formed by amalgamation of several small continental blocks (cratons), micro-blocks and orogenic belts in different paleoclimatic settings. It may be correlated with other continental blocks but has its own specific characteristics. Therefore, the tectonic environments of China’s marine and continental saline basins and salt-and potash-forming environment have some specific characteristics: multiple phases of salt formation, difference in salt-forming ages, migration and concentration of salt-forming processes and diversity of component materials, as well as small sizes of marine saline basins and great changes of saline basins in the late stage and occurrence of liquid mineral deposits. According to the characteristics of the tectonic domains where China’s salt-forming basins are located, the North China, Yangtze and Tarim-Qaidam salt minerogenetic domains and the northern Qiangtang-western Yunnan salt minerogenetic belt may be distinguished. Their salt and potash prospects will be discussed separately.
