The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.

This paper deals with and summarizes the research and importance of ductile shear zones and presents the future direction and aim for the research of the ductile shear zones around the world. Four aspects of studies of the ductile shear zones have been proposed in this paper as follows:(1) The stress environment including the mineral assemblages, deformation, stress-shearing parameters;(2) The major element sequence and activation under condition of stress;(3) The variations of trace elements and REE, their transportation distributions under strong natural deformation as well as variations of mineral crystal parameters, which can also control the element changes during the ductile deformation;(4) The relationship between element migrations, activation and stress, which will present the new evidences for the studies of dynamic diagenesis and mineralization as well as the studies of evolution of ductile shear zones developed in middle and low levels.(5) The analysis of elements and isotopes in mylonites on the micro-scale are crucial for the understanding of component migrations during the mylonization.
