Ore field range in a few general. Hundreds of square kilometers. Such as the metallogenic belt of the middle and lower Yangtze river NingWu metallogenic belt and the concave mountain. Nanshan mineralization area is a mine field. Ore field tectonics is specialized research in ore field, within the scope of control deposit formation, transformation and empty asked distribution of geological structure elements of a subject. It is to research all kinds of stress structure (such as fold, fracture, etc.), also want to study all kinds of thermal structure (such as with hot brine, volcanoes, magma intrusion, etc.) and gravity structure (such as decollement, etc.) the mineralization control, but also to study various deposit type (such as magmatic deposit, hydrothermal deposit, sedimentary deposit, metamorphic deposit, the transformation deposit, etc.) of the ore-controlling structure characteristics, summarizes the field of ore prospecting model for mine geology and mineral exploration direct service. Ore field inside looking for the mines owner if mine geological exploration evaluation work, ore field structure type classification and research, effective prospecting methods combination optimization, etc. Foreign ore field structure is one of the former Soviet union geologists study is fine. The domestic outstanding is the application of the geological mechanics structure analysis, mainly tectonic system classification and structural plane stress analysis of metallogenic regularities and prospecting prediction. Ore field tectonics is only ore field geological aspect. Ore field geological metallogenic regularity understanding not only need to study structure. More major must study the metallogenic build. The ore-forming rock geochemistry and mine geological mining problems. Ore field geology study both ore fields layer, intrusive rocks and volcanic rocks, metamorphic rock, fold belt, fracture rock band and other kinds of geological and deposit related to the structural elements, and research all kinds of deposit type. If magmatic deposit, hydrothermal deposit, sedimentary deposit, metamorphic deposit, the transformation of the ore deposit distribution characteristics and metallogenic process, test and metallogenic tectonic space and time the deposit (body) earth chemical composition, the mineralization geological hierarchy correlation, structure relations and distribution, looking for ore structure rock section. Ore field structure types are classified: according to the structure formation of master mode of action are: (1) the stress structure types. Fold, fracture, joint fissures and cleavage, lineation, etc. : (2) thermal structure types. Geothermal anomaly cluster area, volcanic eruption type, shallow porphyry into inasie, hydrothermal activity, thermal anticline (thermal dome type), deep into the earths crust magma inasie, thermal column type, mantle thermal column type; (3) gravity structure types. Unconformity surface, decollement, meteorites colliding with structure, etc.; (4) composite transformation structure types. Stress and thermal effect composite (thermal anticline, thermal dome, metamorphic core Complex, etc.), stress and gravity composite transformation (unconformity surface to fold, bottom splitting decollement, etc.), thermal and gravity composite (meteorite impact structure, etc.). According to the metallogenic tectonic mode of action are: (1) deposit metallogenic tectonic system. Lithostratigraphic, the calcium silicon surface, cream salt level, ancient karst, unconformity surface, REDOX belt surface, underground water front, sedimentary primary structure interface; (2) the fold metallogenic tectonic system. Fold axis department, turning end, kink deformation belt, plastic flow surface, etc.; (3) fracture metallogenic tectonic system. Fault zone, joint fissures and broken belt, ductile shear zone, brittle. Ductile shearing deformation conversion belt; (4) the magma intrusion metallogenic tectonic system. Rock phase interface, intrusive contact (with), accidental inclusion interface, intrusive contact zone + layer asked slip surface, breccia belt; (5) volcanic metallogenic tectonic system. Volcanic institutions, volcanic facies, volcanic structure and lithology rock phase boundary Surface, volcanic sedimentary basin, times of volcanic rock mass structure; composite metallogenic tectonic system: the above all kinds of structural plane stacking fault, fold structure surface. Ore field geological investigation method and prospecting method is: according to tectonic metallogenic series analysis ore field tectonic lithofacies test and forecast. Geological geophysical remote drilling exploration ideas, the layer ring structure rock phase superposition reconstruction diagenetic problems, analysis of crust-mantle role and deposit types of contact; According to the multi-level structure system and diagenetic metallogenic series ore-controlling rules and explore the ore field geological background, To determine the main controlling factors of the ore field mineralization, the establishment of ore field tectonic lithofacies prospecting marks, the establishment of multi-level structure rock phased ore mineralization and prospecting model, the establishment of the deposit type ore field exploration model. Points out favorable metallogenic tectonic lithofacies section, Through the rock ore deposit geochemical test, test, simulation and theory analysis, and carry out structural geochemistry and physical and chemical structure of metallogenic study, rheological rock tectonic stress and strain test, the establishment of tectonic lithofacies interface, tectonic geochemical interface and structure physical chemical interface prospecting methods; The development of diagenetic metallogenic depth and denudation degree of structure adjustment measure, and points out that the deep prospecting direction; With the development of structural system of metallogenic series of ore field metallogenic theory, improve resource guarantee level, to realize the sustainable development of mining industry service. Research and prospecting method is ore field tectonic lithofacies drawing, ore field structure and ore deposit geology research, rock ore material composition and fabric test research, structure. Fluid. Metallogenic analysis, structural geochemistry and structure physical chemistry research, strengthen the geophysical and remote sensing image processing, simulation, submit ore field concealed ore prediction target area. Deposit prospecting model is an important guidance, ore field is to develop the deposit model in important fields, ore field level deposit model of system greatly development metallogeny and deposit to learn. Ore field prospecting need in prospecting method effective combination optimization, select the appropriate deposit type, strengthen ore field structure and ore field exploration technology combination of effective method to research demonstration. According to the specific deposit type research goal, it is necessary to carry out the corresponding exploration technology integration. According to the deposit model choose effective geophysical technology integration, reasonable exploration model and targeted geophysical parameters, through the exploration for anomaly parameters, which can greatly improve the effect of geological prospecting. 译文：矿田是发育在空间上、时间上、成因上相互联系的一些矿床，存在一定生产矿山的矿化集中地区矿田范围一般在几十几百平方千米。如长江中下游成矿带的宁芜成矿亚带中的凹山南山矿化集中区就是一个矿田。矿田构造学是专门研究在矿田范围内，控制矿床形成、改造和空问分布的地质构造要素的一门学科。它既要研究各类应力构造(如褶皱、断裂等)、也要研究各类热力构造(如与热卤水、火山、岩浆侵入体等)和重力构造(如滑脱构造等)对成矿的控制，还要研究各种矿床类型(如岩浆矿床、热液矿床、沉积矿床、变质矿床、改造矿床等)的控矿构造特征，总结矿田的找矿模型，为矿山地质和矿产勘查直接服务矿田内找矿主要是矿山地质勘查评价工作、矿田构造类型划分和研究、有效找矿方法的组合优选等。国外矿田构造是前苏联地质学家研究较细。国内较突出的是应用了地质力学构造分析法，主要是构造体系划分和结构面应力分析研究成矿规律与预测找矿。矿田构造学仅仅是矿田地质学的一个方面。矿田地质成矿规律的认识不仅需要研究构造更为主要的必须研究成矿建造。研究成矿岩石地球化学和矿山地质采矿等问题。矿田地质学既研究矿田地层、侵入岩、火山岩、变质岩、褶皱带、断裂岩带等各类地质体与矿床相关的构造要素，又要研究各类矿床类型如岩浆矿床、热液矿床、沉积矿床、变质矿床、改造矿床等的组成分布特点和成矿过程，测试与成矿构造时间和空间有关的矿床(体)地球化学成分，研究矿化地质体层次性关联、构造关系和分布规律，寻找含矿构造岩石区段。矿田构造类型划分：按照构造形成的主控作用方式有：应力构造类型褶皱、断裂、节理裂隙、劈理、线理等：热力构造类型地热异常群集区、火山喷发型、浅成斑岩体侵入型、热液活动、热力背斜(热穹窿型)、中深成岩浆侵入型、地壳热柱型、地幔热柱型；重力构造类型不整合面、滑脱构造、陨石撞击构造等；复合转化构造类型应力与热力作用复合(热力背斜、热穹窿、变质核杂岩等)、应力与重力复合转化(不整合面再褶皱、底劈
