| With the study field of copper-gold polymetal metallogeny and prospecting systematic engineering, and the study area of East Tianshan, where is the east part of longitude 88?of Tianshan Xinjiang and on the basis of extensively being collected materials concerning the study field and area, breakthroughs and advances have been made in many aspects, such as: regional metallogenic geological setting, geophysical field, characteristics of geochemistry, classification of metallogenic systems and units, analysis of copper gold polymetallic metallogenic systems (including the study of typical ore deposits), theory of prospecting systematic engineering, prospecting models and their significance for prospecting copper gold deposits, geochemical features of regional landscape of East Tianshan, methods of exploration, method systems of fast following-up geochemical anomaly sources, prospecting and studies of the key metallogenic belts, after twice field works in areas such as Kalatage of Kalatage-Tuwu-Qincheng Cu, Mo, Au metallogenic belt, gold anomalies of Cuiling in Kangguer-Huangshan-Jingerquan Cu, Ni, Au metallogenic belt, 188, 371, and Xibeipo copper deposits (occurrences), 17, 297, and 9562 gold occurrences, Yamansu Fe ore deposit, and geochemical composite anomaly areas of Yabei, Jingxia, Shaquanzi, and Yemashan-Yemaquan in Aqishan-Yamansu-Shaquanzi Fe, Cu, Au metallogenic belt. They are as follows:(1) Guided on the theory of plate tectonics, the geotectonic unit of the study area and its adjacent area are divided into 7 first-order units (4 of them in East Tianshan), and subdivided 24 second-order units (11 of them in East Tianshan). On the basis of which, strata of East Tianshan are divided into two regions, and subdivided into 6 areas, and further into 9 districts, and magmatites of the study area are divided into 7 belts from north to south. Geological characteristics of the main geotectonic units and features of their movement have been studied. The relationship between tectonic, strata, magmatite and ore-forming process are discussed. On the basis of the study of characteristics of regional geophysical field, geochemical background and distribution of trace elements, geophysical and geochemical anomaly area are classified, which pave the way for the study of regional metallogeny and metallogenic system and key metallogenic belts.(2) On the bisis of the analysis of the status and the main achievement of metallogenic system and metallogenic series, metallogenic systems concerned polymetal with copper and gold mainly have been first divided into 2 basic sorts (magma and hydrothermal sort), and subdivided into 9 metallogenic systems, combined with ore-bearing formation and metallogenic background. Main sorts of metallogenic systems, which concerned with copper polymetal ore-forming such as femic- ultrafemic rocks, porphyry hydrothermal, Sedex, volcanic hydrothermal, and with gold ore-forming such as altered rock type in shear belt, epithermal, volcanic-subvolcanic hydrothermal, magma hydrothermal, are further subdivided. Ore-forming produces, ore-control factors, sources of ore and process of ore-forming of these main metallogenic systems are studied on the basis of their typical ore-deposits. Model maps of evolution of metallogenic system sorts concerning copper epithermal in East Tianshan and gold in Kangguer-Cuilin metallogenic belt are first built up after relationships and evolution among them are discussed combined with ore-forming background and evolution processes of tectonics and the distribution patterns in time and space of ore deposits in study area.(3) The history and situation of systematic engineering, and the generation and situation of prospecting systematic engineering are generalized, the concept, main task, basic content and study significance of prospecting systematic engineering are elaborated. The essential factors and the way of prospecting for success are discussed. Based on the study of situationand advances of exploration models and modern surveys for ore-body a...
