英文摘要	This article reviews provenance development on Dickinson diagrams, quartz cathodeluminescence, quartz delta O-18, and discusses their existing problems and future tendency. Dickinson diagrams are used based on conditions including Gazzi-Dickinson point-counting method, sampling in third order drainage, <25% matrix, not strongly weathered, all four diagrams considered and so on. And some problems arise like grain size differentiation, less lithic types, diagenesis, source inheritance and transformation in different tectonic setting, statistical errors, thus much attention should be paid as using. As far as cathodeluminescence (CL) image is concerned, metamorphic quartz with CL dark red is well recognized, nevertheless CL color overlaps between volcanic and plutonic quartz, metamorphic and igneous quartz, plutonic and hydrothermal quartz, leading to unreliable interpretation. Instead of CL color analysis, combination of CL-SEM (scanning electron microscope) on textural features with optical microscopy allows reliable distinction of quartz varieties. The last is about oxygen isotope of quartz (i. e. delta O-18). Though chert and igneous quartz could be distinguished from each other by delta O-18, metamorphic quartz is formed so complicatedly that its delta O-18 shows great variation and shares some common values with both delta O-18 of igneous quartz and chert. Clastic composition is controlled by source rocks, modification of chemical weathering, mechanical disaggregation, hydrodynamic sorting, authigenic inputs and diagenesis, therefore source rocks recovery necessitates exclusion of other influencing factors which could be modelled on modern environment by a priori, and integration of other useful methods (e. g. detrital zircon U-Pb ages, epsilon(Nd) etc.) for exact provenance interpretation.
