伏牛山汝阳南部钼铅锌矿集区遥感地质特征

东秦岭东段伏牛山汝阳南部钼铅锌矿集区是河南省重要的成矿带,在利用地物化遥综合信息找矿过程中,遥感地质应用技术发挥了重要作用。大区域成矿带的首选是深大断裂和大型韧性剪切带或其附近,特别注意热动力岩块的指示作用;区域线性断裂束与钼铅锌矿的关系密切,而环形构造是一系列侵入岩体的具体反映,尤其是与花岗斑岩岩浆活动密切相关的高温热液钼矿床与环状构造或其组合构造的影像信息直接相关。遥感地质分析中的有利信息离不开基础地质和矿产地质,只有在充分了解成矿地质条件和矿床赋存规律的情况下遥感地质才能发挥其重要作用。

Remote sensing geology of the south Ruyang molybdenum, lead and zinc deposits clustered area

The South Ruyang molybdenum, lead, zinc deposits clustered area at Funiushan mountain in Eastern Qinling mountain is one of the important ore fields in Henan province. The remote sensing geological technique plays an important part in comprehensive information (geophysics, geochemistry and remote sensing technology) prospecting. The remote sensing technique is favorite for lineation of the regional metallogenic belts, such as large deep faults and ductile shear zones, especially heat dynamic rock blocks near to them, regional fracture bundles which are closely related to molybdenum, lead, zinc deposits, ring structures which are reflection of intrusives, especially granitic porphyry which is closely related to high temperature Mo deposit. However, extraction of the useful remote sensing information depends heavily on the basic geological and mineral resources knowledge. Only with full understanding of the ore-forming geological conditions and ore occurrence regularity here remote sensing technique could play role in the prospecting.
