Abstract

The Boudahar massif is located in the southern part of the eastern belt of the Moroccan High Atlas and it corresponds to a reef mass of about ten kilometers in length. Jbel Boudahar is a district of lead-zinc-barite mineralization, known by a strong artisanal exploitation of its ores. This district is characterized by its topography with a contrast of altitude and an arid environment, which makes the information acquired more valuable. The processing of Landsat 8 OLI data allowed us to extract a lithological and structural map, aiming to make correlations to understand the distribution of lead-zinc mineralization. To this end, several tests were carried out, including the composition of color, principal component analysis and band ratio transformation. The location of the main deposits at Jbel Boudhar coincides well with the lineament derived from band 1 of principal component analysis and with the dolomitic pliensbachian formations mapped by MNF and BR from Landsat Oli8. A remote sensing geological prospecting model has been established for the Jbel Boudhar lead-zinc deposits, providing a basis for future prospecting of new deposits in a similar context.

Landsat 8 OLI图像对岩性系列和地貌的贡献:对摩洛哥东部高阿特拉斯地区Boudahar地块铅锌矿化勘探的意义

Boudahar地块位于摩洛哥高阿特拉斯东部带的南部，与一个长约10公里的礁体相对应。Jbel Boudahar是一个铅锌重晶石矿化区，以其矿石的强大手工开采而闻名。这个地区的特点是它的地形与海拔的对比和干旱的环境，这使得获得的信息更有价值。对Landsat 8 OLI数据的处理使我们能够提取岩性和构造图，旨在建立相关性，以了解铅锌矿化的分布。为此，进行了颜色组成、主成分分析和波段比变换等测试。Jbel Boudhar主要矿床的位置与主成分分析第1带得到的地貌和Landsat Oli8卫星上MNF和BR所绘的白云质pliensbachian地层吻合较好。建立了Jbel Boudhar铅锌矿遥感地质找矿模型，为今后在类似背景下找新矿床提供了依据。
