　　Summary:
　　Bauer plans Xinjiang Tarim plate copper bed in the northern margin of Uva door - Bauer figure faults south of the low level of deposits. Through field surveys, analysis of major elements, trace elements and other means of Bauer Figure copper deposits and rare earth magnets geochemical characterization of a preliminary study, and the gray model to predict long-term mineralization at depth, the main results obtained are as follows:
　　Geological features: The deposit occurs in phyllite, biotite-plagioclase schist, gneiss, a metamorphic rock, mixed in three ore body. Vein was the main ore body, about 100m ~ 670m, metallic minerals are mainly chalcopyrite, pyrite and pyrrhotite, non-metallic minerals as feldspar, quartz and sericite, etc. Ore grade of 0.23% to 6.08%. Mineralization consists of quartz vein stage, sulfide - quartz vein stage, quartz - carbonate veins phase.
　　Geochemistry: Ore ΣREE large relative changes in value (ΣREE = 2.1ppm ~ 139.6ppm), LREE / HREE = 0.06 ~ 0.97, significant differentiation LREE and heavy rare earths are relatively enriched. Partition curve is a left-leaning type, and mixed rock vein similar REE patterns, indicating mineralization and migmatization related. By tectonic environment http://www.chinamagnets.biz/ discriminant analysis, the study area feature points mixed rock vein with the majority of fall-related collision volcanic island arc environment, Bauer plans to conclude the causes of type copper deposit is controlled by faults hydrothermal metamorphism copper deposits.
　　Deep Forecast: grade of ore through the establishment of the gray model to predict 18-4 orebody extends to the deep, grade and gradually become larger. The forecast results for the deposit of the deep exploration provides a theoretical basis.
