Proterozoic was an important epoch on the evolving Earth, and the Proterozoic lithology record critical information for Precambrian evolution of the Earth. Exact interpretation of petrogenesis is the foundation of tectonic study, which is also significant for ecology study. The Changcheng formation, which is composed mainly by layered siliceous lithology, is one of the most important lithology exposed in the northern North China Craton. Former study considered this siliceous lithology as low degree metamorphic marine siliceous sediment suit under rift setting. In this study, based on field geology, petrography, SEM/EDS, CL, in-situ LA-ICP-MS analysis of quartz, combine with melt inclusion petrography, microthermometry, muffle furnace heating-quenching experiments, SEM/EDS, EPMA and Raman analysis, we propose volcanic origin of layered siliceous rocks in the bottom of Changcheng formation. Our results show that the layered siliceous rocks from Changcheng formation of Huyugou have two structure types, including detrital structures (previously named as quartz sandstone) and mosaic Structure (previously named as quartzite). Mineral assemblage of layered siliceous rocks are mainly quartz and K-feldspar with minor zircon, rutile. Quartz and K-feldspar in detrital rocks exhibit angular to subangular shapes, and K-feldspar does not perform clayey edge. The CL image of quartz in two types of rocks is generally blue to purple in color. Ti-in-quartz geothermometer reveal that the crystallization temperature of quartz is among 550~650°C, indicating they are high-temperature quartz.Both quartz and K-feldspar of the two types of rocks contain two-phase Fe-Ti rich melt inclusions. The microthermometry study of the melt inclusions indicate that the immiscible components of the two phases continue to change during the heating process from 1 000 °C, and we also obtained a homogenization temperature at around 1 350 °C. The muffle furnace heating-quenching experiment also confirmed that the two-phase melt inclusions in the samples were homogenized at around 1 350 °C. The SEM/EDS and EPMA results indicate that the main components of the melt inclusions are Fe- and Ti-oxides. The dark parts are relatively Fe-rich, while the light parts are relatively Ti-rich. The Fe/Ti values of the two phases in melt inclusions are varying. The LRM analysis results indicate that both phases of the melt inclusions are amorphous. Based on the rock structure, CL characteristics and crystallization temperature of quartz, and melt inclusion microthermometry of quartz, we propose that the silicon rich layered lithology at the bottom of the Changcheng formation should be siliceous volcanic-volcanic clastic rocks, which also indicate that there was large-scale siliceous volcanic activity related to the breakup of the Columbia supercontinent during the Paleoproterozoic in North China Craton. This discovery provides new evidence for the Precambrian geological evolution of the North China Craton. The discovery of Fe- and Ti-rich melt inclusions in quartz also provides new insight for explaining the formation of Precambrian magmatic Fe and Fe-Ti deposits, especially the enrichment mechanism of Fe and Ti in magmatic processes.
