摘要
内蒙古小井子地区位于黄岗梁-白音诺尔-大山寨Ⅳ级印支-燕山期铁锡钼-银铅锌成矿带、白音诺尔-双尖山-浩布高Ⅴ级华力西-燕山期银铅锌成矿带中,属白音诺尔-浩布高大型铅锌矿的外围地区。本文运用数字图像处理方法从遥感数据中提取铁化蚀变信息,结合已有金属矿点信息,分析小井子地区矿点在铁化蚀变异常分布特征,认为铁化蚀变异常与矿体吻合关系好,可作为找矿标志;遥感蚀变异常定位精度高,异常范围小,更接近矿体,应用于化探异常查证可以提高查证效率。该方法技术适合于寻找与热液活动有关的金属矿产,有助于发现具有找矿潜力的靶区。
Xiaojingzi region of Inner Mongolia is located in Huanggangliang-Bainyinnuoer - Dashanzhai IV level Indosinian to Yanshanian iron tin molybdenum-silver lead-zinc metallogenic belt, baiyinnuoer-shuangjianshan - haobugao V level variscan-silver lead- zinc metallogenic area in Yanshanian period, is a large Baiyinnuoer-Haobugao Knoll lead-zinc mine periphery. Method of digital image processing is used to extract iron mineralization alteration information from remote sensing data, combined with the existing metal point information, the little well of a sub regions mines in the iron mineralization alteration anomaly distribution characteristics are analyzed, that iron mineralization alteration anomalies and ore body fit good relations, they can be used as ore-prospecting criteria. Remote sensing alteration anomaly location accuracy is high, the abnormal range is small, and is closer to the ore body, the application of the geochemical anomalies can improve the efficiency of verification. Technology is suitable for this method to find related hydrothermal activities in the metal minerals, and it is helpful to find a target area of prospecting potential.
