摘　　要：The melt rocks produced during an underground nuclear explosion in the limestone medium may be classified into three types in the light of thin-section examinations and chemical compositions. One of them is the carbonate melt rock which is distributed widely and very large in quantities. About 20 kinds of monominerals were identified by X-ray powder and electron microprobe techniques. Some minerals, such as moissanite, brownkillerite, Ca12Ah14O33, etc., are rare or have not yet been discovered in nature. In addition, this paper presents the four stages of formation of the melt rocks, i.e., the vaporization-liquefaction stage, the initial crystallization-cavity stripping stage, the crystallization stage, and the chimney formation-thermal metamorphism stags. Furthermore, preliminary theoretical analysis was carried out of the physico-chemical process of mineral formation.The melt rocks produced during an underground nuclear explosion in the limestone medium may be classified into three types in the light of thin-section examinations and chemical compositions.
