The red dot and flame figure inclusions in Nanhong jade are red spherulite and red tube-like inclusions in quartz. Microscope observations and scanning electron microscope studies show that the red spherulites include the red core, black coccosphere and red surface, and are distributed in the intermittent layers of rhomb in "three-color" type quartz. The flamed tube-like inclusions mainly occur in striped quartz, perpendicular to the rhomb of quartz. The interior of the tube is black with red shell. The color and transparency of the spherulite and red tube-like inclusions have directly effects on the color and luster quality of Nanhong jade. Studies show that the red spherulite and red tube-like inclusions are mainly composed of platy hematite. The directions of c-axis in hematite from spherulites change regularly, which is likely related to its V₂O₅. The relationships between quartz and associated minerals and their analytical results indicate that hematite is of hydrothermal origin, and its temperature is about 160℃. The organic matter of the fluids, which led to the formation of spherulite and red tube-like hematite inclusions, probably came from the carbonate in Permian Maokou Formation.
