However, the associated lithic assemblage, more than 80% composed of quartz, has so far remained understudied. Although widely used during the Pleistocene and the Holocene, quartz, the most abundant mineral on Earth, has been traditionally considered as a \u201csecond-rate\u201d resource. Due to the raw material\u2019s specific fracture mechanics, quartz lithic assemblages have the tendency to be typologically and morphologically less standardized than flint ones. For these reasons, studies of quartz assemblages have been few and far between, especially when flint and quartzite ones, easier to analyze, are found alongside. Following techno-typological and techno-economic approaches, we carried out a study of a sample of quartz cores and blanks from three successive Figueira Brava human occupation phases spanning the 86-106 ka (thousands of years ago) interval. The results show that several reduction methods were successfully applied, displaying good management of the mechanical properties of the raw material. Alongside the Bipolar-on-Anvil technique, methods such as Levallois and Discoid were used, albeit following strategies somewhat different than with flint and quartzite. At Figueira Brava, the use of quartz \u2013 abundant locally and skillfully worked through a diverse range of reduction methods \u2013 reflects the good adaptation of the cave dwellers to their environmental context.<\/jats:p>","DOI":"10.5852\/cr-palevol2025v24a28","type":"journal-article","created":{"date-parts":[[2025,12,9]],"date-time":"2025-12-09T13:15:59Z","timestamp":1765286159000},"source":"Crossref","is-referenced-by-count":0,"title":["The Middle Paleolithic quartz assemblage from Gruta da\u00a0Figueira Brava (Portugal)"],"prefix":"10.5852","volume":"24","author":[{"given":"Maria N.
