Abstract - Summary 
(short description):
High-temperature combustion metamorphic (CM) complexes of the Hatrurim Formation occur in the vicinity of the Dead Sea valley. The appearance of CM rocks is believed to be genetically related to the explosions of ancient mud volcanoes. This process has been accompanied by methane combustion. A set of veins of melted CM rocks (paralavas) were distinguished at the Hatrurim Basin, Israel. They consist of mineral associations typical for ultra-high-temperature sanidinite facies rocks. Melilite, wollastonite and pseudowollastonite, rankinite, kalsilite, and schorlomite are rock-forming minerals. Nagelschmidtite, Fe-perovskite, Ni-magnetite and fluorapatite are minor constituents. The high-temperature nature of the rocks is additionally conformed by the peculiarity of mineral compositions. According to mineralogical data the temperature of rocks heating during gas combustion attained 1200ºC.
