Quartz  is widely distributed  in  the  igneous, sedimental and metamorphic  rocks, and hydrothermal ore deposits. As
its specific stability  in composition and  texture, quartz does carry   much more petrogenetic and metallogenic  information  than
other rock-forming minerals. Quartz, originated from different stages of magmatic-hydrothermal system and/or different geological
settings, shows great differences  in  its  lattice  texture and distribution of  trace elements, because of  its different behavior  in  the
history of geological processes. To interprate the factors affecting trace elements entering  quartz lattice and find out high-sensitive
elements  in particular geological environments,  the  trace element distribution and  textural characteristics of quartz  lattice are
investigated by use of micro-area in situ technique and cathodeluminescence. Therefore, the provenance of quartz formation can
be traced, and then useful geological-geochemical information about the petrogenesis and metallization can be deduced. Moreover,
as shown in this paper that there is a linear relationship between Al, Ti contents and the formation temperature of quartz. It might
be extensively used as a tentative geothermometer.

Key words: trace element, petrogenesis and metallization, cathodeluminescence, geothermometer, quartz lattice
