2026-01-09 Original data-In situ observations of gold deposition in a dense liquid layer at the pyrite-water interface doi:10.57760/sciencedb.24759 en ex-situ TEM: We used ex-situ TEM to analyze the surface morphology, microstructure, and elemental distribution of synthesized pyrite powders after reaction with chloroauric acid solution.in-situ TEM: We employed in-situ TEM to observe the dynamic nucleation process of gold nanoparticles at the pyrite-chloroauric acid solution interface.in-situ AFM: We utilized in-situ AFM to investigate the dynamic growth process of gold nanoparticles at the pyrite-chloroauric acid solution interface.optical microscope photographs: We employed optical microscopy to examine the spatial relationship between pyrite and native gold in Jinshan gold deposit.SEM+XRD: We used XRD and SEM to analyze the crystal structure and micro-morphology of synthesized pyrite powders.XPS: We utilized XPS to detect the chemical environment evolution on pyrite surfaces after in-situ AFM reactions.These data provide critical insights into the in-situ nucleation and growth processes of gold nanoparticles at the pyrite-water interface, significantly advancing our understanding of gold mineralization mechanisms. pyrite; gold; in-situ liquid-phase reaction Hongmei Tang Haiyang Xian Teng Deng Zhaolu He Shan Li Yiping Yang Honggang Liao Youhong Jiang Jiaxin Xi Jianxi Zhu Hongping He PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
