摘要
Abstract
In this paper,the microscopic characteristics of Baoshan South Red Agate are studied through super-depth-of-fieldmicroscope,polarizing microscope and electron probe backscatter images.Its mineral composition and chemical composition are analyzed using X-ray diffraction and energy spectroscopy,and the attribution of ore-bearing strata is discussed by summarizing previous geological data.The results show that the main mineral composition of Baoshan South Red Agate is quartz,and the accessory minerals are hematite and calcite.It has an cryptocrystalline structure and a strip structure.Its microscopic strip structure reflects its multi-stage metallogenic characteristics.In the later period,siliceous magma hydrothermal solution filled the basalt pores and precipitated and crystallized layer by layer from the outside to the inside or crystallized along the fractures of the rock mass to form Baoshan South Red Agate.Hematite is a coloring mineral of South Red Agate,and its content and distribution density are positively correlated with the color depth and uniformity of agate.In this paper,the basalt of the Woniusi Formation in the late Early Permian of Baoshan block is determined as the ore-bearing site of the red agate in the south of Baoshan.关键词
