However, this research introduces not only as the origin of breccia but also as a trigger for a variety of SSDS. These deformation features are primarily associated with the dissolution of anhydrite in Noumerat sedimentary succession, located on the Mzab Plateau in the Northern Algerian Sahara. As the anhydrite dissolved, the overlying claystones subsided into collapse troughs, accompanied by lateral sliding, forming distorted structures such as dome-like folds, water-escape structures, and slump structures. Furthermore, the presence of faults and cracks within the anhydrite layers significantly accelerated dissolution, promoting the formation of breccia fragments within the karst system. This underscores the chemical instability and rapid dissolution of anhydrite. The presence of secondary gypsum-bearing claystones, along with evidence of unconformity, and unconformities further supports this interpretation.</div></div>","PeriodicalId":49672,"journal":{"name":"Proceedings of the Geologists Association","volume":"136 5","pages":"Article 101134"},"PeriodicalIF":1.3,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work is based on field evidence and includes moraine ridges, fan landforms and sediments, along with the results of varve analyses from the Roy and Laggan valleys published elsewhere. The results suggest that, apart from some small corrie glaciers at the south side to the Roy-Spey watershed, much of the area was deglaciated following the Western Ross Readvance (<em>c.</em> 15.4–15.8 cal ka BP), prior to glaciers of the Loch Lomond Readvance (<em>c.</em> 12.9–11.7 cal ka BP) reaching the well-defined limits that held back the glacial lakes. The process of ice wastage within Glen Roy, from the Wester Ross Readvance, involved ice-marginal fluctuations, minor readvances and the formation of a pro-glacial lake related to the col at the Roy/Spey watershed. It is also proposed that many of the fans that occur along the sides of Glen Roy are of subaerial origin formed by paraglacial processes, rather than as subaquatic lake deltas.</div></div>","PeriodicalId":49672,"journal":{"name":"Proceedings of the Geologists Association","volume":"136 5","pages":"Article 101131"},"PeriodicalIF":1.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
