摘　　要：根据苏丹红海州辛卡特矿区遥感影像蚀变异常信息提取,圈定出了铁染蚀变异常区3处,羟基蚀变异常区3处,铁染和羟基蚀变异常叠合区1处。然后对异常区进行地质填图、槽探、民采工程清理工作,圈定出了矿化蚀变带8条,矿化体23个,取得了较好的找矿成果。本文归纳出了辛卡特矿区矿床成因类型为造山型金矿。总结了地质、遥感找矿标志,提出了找矿前景。并提出了“遥感+地质”的找矿模式,在苏丹红海州地区的找矿有较好的示范作用。According to the extraction of alteration anomaly information from remote sensing images in Sinkat mining area in Red Sea State of Sudan,three iron-stained alteration anomaly areas,three hydroxyl-stained alteration anomaly areas and one overlapping area of iron-stained and hydroxyl-stained alteration anomalies have been delineated.Geological mapping,trench exploration and civil mining engineering cleaning have been carried out,and 8 mineralized alteration zones and 23 mineralized bodies have been delineated.Good prospecting results have been achieved.In this paper,the type of ore deposits in Sinkat mining area is orogenic gold deposits.Geological and remote sensing prospecting indicators have been summarized,and the prospecting prospects have been put forward.The prospecting model of"remote sensing+geology"has been put forward.It has a good demonstration role in prospecting in Red Sea State of Sudan.
