Exploration practices for blind ore bodies of Anshan-type iron deposits in Liaoning Province: Breakthrough in iron prospecting in the easternmost section of Dong'anshan

Through in-depth research on the metallogenic conditions and ore-hosting strata characteristics of blind ore bodies in Anshan-type iron deposits, this paper employs a comprehensive application of geophysical methods such as aeromagnetic, ground magnetic, gravity surveys, and electrical explorations to delineate the extent of blind ore bodies of Anshan-type iron deposit. By drilling verification and borehole three-component magnetic surveys, as well as scientific and rational arrangement of exploration engineering, the blind ore bodies of Anshan-type iron deposit have been discovered — a significant breakthrough in prospecting efforts. This discovery has not only added substantial iron ore resources and reserves but also provided valuable reference for the exploration of blind ore bodies in Anshan-type iron deposits of Liaoning Province.
