Experimental researches constitute one of the sources of the innovation of granite and adakite theory and hence play an essential role in this aspect. In recent years, researchers in China have made great achievements in granite and aidakite experimental research. This paper discusses some experimental researches on issues related to adakite and puts forward some opinions: ① The bottom of the lower crust lacks water, the dehydration partial melting of granite is under the condition of less water, and hence the experimental results should be treated with caution in the case of saturated water and increased water; ② Attention should be paid to the problem whether there appears plagioclase in the residual phase component or not, and the consideration of both garnet and plagioclase can lead to a correct conclusion; ③ What is the real meaning of garnet-in line under 1.0 GPa pressure? It only suggests that the melt balance with garnet-in has lower Yb. However, besides adakite, Himalayan type granite also has lower Yb, and therefore the emergence of plagioclase should also be considered: if garnet appears but plagioclase disappears, the melt is adakite; if both garnet and plagioclase appear, the melt is the Himalayan type granite. Researches abroad fail to consider Himalayan-type granite, and hence some experimental data under the condition of 1 GPa provided by foreign researchers should be used carefully, because some of the melts belong to the Himalayan type granite instead of adakite; ④ The metamorphic reaction is different from the partial melting reaction. The metamorphic reaction result cannot be interpreted as the result of partial melting reaction. The metamorphic reaction occurs in the case of increasing temperature and pressure and is not the main way to produce granite; the partial melting reaction that occurs under the constant pressure and increasing temperature is the main way to produce granite. The author emphasizes that the recent experimental study of adakite conducted by researchers in China has made great progress, and China is at a leading level in the world in this field. The difference in opinions is inevitable and normal.
