The northern part of the Middle Atlas is the most deformed of the chain. Made up of essential carbonate and marly outcrops of Jurassic, it shelters a particular karstic richness. Its integration into the Moroccan geoheritage is amply justified by its diversity, its typicity, and its exceptional extent. Indeed, its exokarstic forms cover 30% of its surface and its endokarst includes, to date, more than 370 underground cavities. Among the main karst geosites of the northern Middle Atlas, 9 have been inventoried and studied in this article based on four scientific criteria, namely, representativeness, rarity, geological diversity, and documentation. We consider these geosites as reference and unique sites for Morocco. Out of 9 inventoried geosites, 6 geosites are exokarstic (Chiker polje, dolines of Ademame, Chaâra lapiaz, Guelta Tameda, Taffert canyons, Aïn Sebou) and 3 geosites are endokarstic (Chiker cave, Ras El Oued, Chaâra cave). These geosites, presenting various phenomena with remarkable lithological, morphostructural, and paleoclimatic features, hold high scientific value and bear witness to the geological evolution of this region.

中图集的北部是链条中变形最大的部分。它由必需的碳酸盐和侏罗纪的沼泽露头组成，可以掩盖特别的岩溶。它的多样性，典型性和卓越的范围充分证明了其与摩洛哥地质遗产的融合。的确，它的exokarstic形式覆盖了其表面的30％，其内岩溶迄今包括了370多个地下洞。本文基于代表性，稀有性，地质多样性和文献记录这四个科学标准，对中北部北部主要喀斯特地貌进行了盘点和研究，共计9个。我们认为这些地理位置是摩洛哥的参考和独特地点。在9个清单上的地理位置中，有6个地理位置是外来的（Chiker polje，Ademame，Chaâralapiaz，Guelta Tameda，塔弗特峡谷，埃因塞布（AïnSebou）和3个地质地点属于内核岩（奇克尔洞，拉斯埃尔·乌埃德（Ras El Oued）和查拉洞）。这些地质位点呈现出具有显着的岩性，形态结构和古气候特征的各种现象，具有很高的科学价值并见证了该地区的地质演化。
