Abstract

This data article associated with the manuscript "Magnetic mineral dissolution recorded in a lacustrine sequence from the Heqing Basin, SW China, and its relationship with changes in the Indian monsoon". Through detailed rock magnetic measurements, magnetic properties of the lacustrine sediments (magnetic mineralogy, their concentration and domain state) were clarified. Then, analyzing the relationship between magnetic property and paleoenvironmental proxies can reveal the paleoenvironmental implications of magnetic parameters of lacustrine sediments from the Heqing basin. Comparing paleoenvironmental proxies of lacustrine sediments from the Heqing basin with proxies associated with Indian monsoon recorded in Arabian Sea, and Bay of Bengal, can deepen our understanding about the characteristics of Indian Monsoon in the geological time.

Keywords: Indian monsoon; Magnetic mineral dissolution; Rock magnetism; The Heqing basin.
