多龙深部找矿靶区

本次研究基于对前人资料整理和地球物数据的再解译，识别出具有深部岩体特征的隐伏深成侵入，综合高精度遥感影像提取环形构造重新建了多龙矿集区域成模式。自晚侏罗世始，在羌塘南缘早期弧岩浆作用下，多龙矿集区一带开始发生弧岩浆作用，形成OIB型基性侵入岩，同时深部岩体在地壳上部形成。岩浆不断上侵，导致铁格山地区和鹫山地区的隆起，伴随形成表岩浆和鹫山地区的隆起。随着浆持续侵位，地表脆性岩石破裂形成围绕深部体发育的一系列环构造和围绕侵入中心的放射状构造，其交切部位形成应力薄弱地带，为后期浅斑岩浆位和成矿提供空间初始条件。

This study is based on the collation of prior literature and the re-interpretation of geophysical data, identifying buried plutonic intrusions with deep rock mass characteristics. By extracting circular structures from high-resolution remote sensing images, the metallogenic model of the Duolong ore concentration area was reconstructed.

Starting from the Late Jurassic, under the influence of early arc magmatism on the southern margin of the Qiangtang Terrane, arc magmatism commenced in the Duolong ore concentration area, forming OIB-type mafic intrusive rocks while deep rock masses formed in the upper crust. Continuous upward magma intrusion led to the uplift of the Tiegeshan and Jiushan areas, accompanied by the formation of shallow magma and the uplift of the Jiushan area. As magma continued to emplace, brittle surface rocks fractured, forming a series of circular structures surrounding the deep rock mass and radial structures centered on the intrusion. The intersecting locations of these structures formed stress-weakened zones, providing initial spatial conditions for the subsequent emplacement of shallow porphyritic magma and mineralization.

All geophysical and geochemical exploration work involved in this study was commissioned to a professional geological team. The work and data related to geophysics, geochemistry, short-wave infrared (SWIR) spectroscopy and other related contents were all completed by the commissioned geological team. The work was carried out with high completion quality, and the data is of excellent quality, having submitted deep ore-prospecting targets for the Duolong ore concentration area.
