| Preliminary Study on Tectonic Frictional Heat |
| Tectonic frictional heat is an important topic of basic theory in geology. During the geological process, tectonic frictional heat can not only speed up the deformation of rocks, but also result in the metamorphism and melting of rocks, bring about synchronic geochemical process. The formation of many endogenous deposits was related with tectonic frictional heat . After the mathematical calculation and analysis on the examples of tectonic frictional heat, the authors present that: tectonic frictional heat varies directly as sliding velocity of both sides of rocks and compressive stress, and sliding velocity is the predominant factor. Tectonic frictional force is related to a angle between the frictional plane and σ 1,and out of measure .Frictional heat varies as change of θ which is angle between σ 1 and frictional plane .There are 1～2℃at frictional plane ,when σ 1 =50MPa ,θ≈30°. |
