Quaternary Urban Geology and the Foundation of Heritage Building: Notable Historical Cases in Sawahlunto, Indonesia

Heritage buildings in Sawahlunto, Indonesia, primarily use sedimentary rocks sourced from the Ombilin Basin, reflecting both historical and geological significance. This study reveals that local materials were predominantly used due to their abundance during the Dutch colonial era, contributing to the city's unique urban geological heritage. The research employed mixed methods, including geological mapping and content analysis, to identify rock types, topographic features, and building materials, while also analyzing their distribution and origin. These findings highlight the importance of integrating urban geology into heritage conservation efforts, particularly for UNESCO World Heritage Sites like Sawahlunto.
