Karst-hosted Mississippi Valley-type Pb–Zn mineralization in fold-thrust systems: a case study of the Changdong deposit in the Sanjiang Belt, China

A karst-inspired hierarchical Mg/Al layered double hydroxide with a high entropy-driven process for interception and storage

“…7,8 Some bauxite deposits are identified in carbonate rocks, and lead, zinc, and sulfide deposits are discovered in ancient karst caves. [9][10][11] Nearly a half of oil and gas resources are stored in carbonate reservoirs, and many large oil and gas fields are closely related to carbonate rocks. 12,13 At the same time, groundwater is vital for supplying water and protecting biological diversity.…”
