遥感影像解译的不同规模级别的线性构造、不同类型的环形构造和线-环组合类型以及色彩异常影像是寻找斑岩铜矿,特别是大型斑岩铜矿床最有用的遥感标志。1.砂岩铜矿的规模直接与不同规模不同级别的线性构造相联系区域性斑岩铜矿带直接受大型区域线性构造带和它们的汇聚格局控制,这种区域线性构造带多为区域压性壳断裂或超壳断裂,在遥感图像上常显示为浅色带,其长度超过100km,被称为主干边缘线性构造带(处于隆起单元向坳陷单元过渡部位,靠近隆起单元一侧)。此外,一系列次级线性构造往往与主干边缘线性构造成一定角度相交,共同形成一种贯通性构造,在遥感图像上也常显示为浅色线;并直接控制斑岩铜矿田的分布和矿床的定位,被称为横向线性构造,长度一般1km-100km,主要包括三种类型(略),均显示张性特征。事实上,与斑岩铜矿有关的蚀变矿化直接受控于更低级别的线性构造(断裂和裂隙),它们常构成统一的环状和放射状断裂、裂隙系统。2.不同组合的多层环形影像是斑岩铜矿的不同呈矿环块构造的映像几乎所有的斑岩铜矿都与环块构造有关,特别是Ⅲ或Ⅳ级环块(直径50km-500km,包括环隆、环陷及褶皱-断裂环块等)。它们控制了斑岩铜矿的定位。在火成环块中,铜矿?
Different scales of linear structures, different types of ring structures and line-ring assemblages and color anomaly images interpreted by remote sensing images are the most useful remote sensing signs for finding porphyry copper deposits, especially for large porphyry copper deposits. 1. The scale of sandstone copper deposits is directly related to the linear structures with different scales and different scales. The regional porphyry copper belt is directly controlled by the large-scale linear structural belt and their convergence pattern. The linear structural belt in this region is mostly the regional crustal fault Or superfamily rupture. It is often shown as a light color band on remote sensing images. Its length exceeds 100 km and is called the trunk edge linear tectonic zone (at the transition from the uplift to the depression and close to the uplift). In addition, a series of secondary linear structures often intersect at a certain angle with the linear edge of the main edge to form a continuity structure, which often appears as a light-colored line on the remote sensing images. The distribution of the porphyry copper ore fields and The location of the deposit, known as the horizontal linear structure, the general length of 1km-100km, including three types (omitted), all show the tensile characteristics. In fact, altered mineralization associated with porphyry copper is directly controlled by lower-level linear structures (faults and fissures) that often form a unified ring and radial fracture and fracture system. 2. Multi-layer annular images of different combinations are images of different ore-ring blocks in the porphyry copper deposit. Almost all porphyry copper deposits are related to the ring block, especially ring blocks of type III or IV (50km-500km in diameter, including Ring, ring trapped and fold - fracture ring block, etc.). They control the location of porphyry copper deposits. In the ring of fire, copper?
