苏丹矿产分布图 - They all belong to the calc - alkaline island arc series and are closely related to the evolution of the arc - basin systems of the gangdise tectonic belt . based on studies of petrology , litho - geochemistry , tectonic setting , petrogenesis and magmatic evolution , the present dissertation summarized the general evolutionary regularity of the magmatic rocks in time and space . the magmatic rock assemblages are divided into the inter - arc spreading basin t
在对研究区主要矿产分布特征、成因类型系统分析的基础上，总结了措勤地区构造岩浆演化与成矿的关系，并将研究区成矿系统划分为汇聚大陆边缘成矿巨系统、碰撞造山成矿巨系统和陆内汇聚成矿巨系统。 - Abstract : based on 1 200000 aeromagnetic survey data performed in 1998 , and referred to materials of geolo - gic and geochemical prospecting of the working area , this paper discusses the relationship between the characte - ristics of magnetic field , magmatic rocks , fault structure and the distribution of mineral resources , and investigates the geologic metallogenic environments , and sets up the prospecting criteria for hydrothermal and volcanic - sedimentary copper , lead , zinc , gold , iron , manganese deposits , then makes the prognosis of the prospecting potential of the working area
文摘:本文以1998年1 20万航空磁测资料为基础，参考地质和化探资料，对工作区磁场特征、岩浆岩、断裂构造与矿产分布的关系进行探讨，研究地质成矿环境，建立寻找热液型和火山-沉积型的铜、铅、锌、金、铁、锰矿找矿标志，对本区找矿远景进行了预测。 - Such a division may better reflect the minerals distribution and formation laws , more accurately guide prospecting . 4 , research on model copper deposits the copper deposits related to intermediate - acidic volcanic - intrusive complexes are widespread in eastern tianshan . they can be divided into these types : ( 1 ) porphyry type ; ( 2 ) skarn type ; ( 3 ) volcanic type ; ( 4 ) copper - nickel sulphide type
