Geochemical characteristics and geological significance of rocks in the Longxinzhuang Area of Eastern Hebei Province

The Longxinzhuang Area is located within the key exploration zone of the Jidong Jinchangyu-Kuancheng Huajian Gold Mine, and it has a promising prospect for mineral exploration. To explore the mineral exploration potential of the study area, surface rock measurement work is carried out, and eight elements including Au, Ag, Cu, Pb, Zn, As, Sb, and Hg are analyzed. The research shows that Au and As Sb shows a good positive correlation and migrates and accumulates together in the ore-forming hydrothermal fluid. As Sb has an indicative main factor F1（Au, As, Sb） for the exploration of Au, which is the main ore-forming stage, indicating that the mineralization of gold is closely related to sulfides. Through engineering verification, two gold-bearing vein zones are discovered, reflecting that this area has good potential for mineral exploration.
