Geochemistry characteristics of Jiudingshan Alkaline-rich intrusions The geochemical compositions were measured at state key laboratory of ore deposit geochemistry, Chinese academy of science, these data showed that SiO2 contents are 61.37%~77.28%, and belonging to acid rock.
Therefore, alkaline-rich magmas are derived from enriched lithospheric mantle hybridized by crust materials, mainly formed in a post-collisional intraplate tectonic setting.

It was found that the degree and characteristics of crystals in vitrified sludge significantly correlate to the alkalinity of the raw materials.
The production of glass-ceramic seems to be a promising method due to the immobilization and stabilization of hazards materials, volume reduction [4-6].
Materials and Methods Sewage sludge used in experiments was collected from an urban wastewater treatment plant in Harbin, China.
