This research characterizes petrographic and geochemical properties of rocks in Central Sulawesi, revealing insights into megalithic resource selection at archaeological sites.
Key Points
The study reveals that megalithic builders used locally sourced rocks with significant durability for construction.
Analysis of seven rock samples shows five are plutonic igneous, classified as quartz monzonite and monzonite.
Petrographic and geochemical methods demonstrate strong geological-cultural links in the material selection process.
This research enhances understanding of lithic technology and contributes to the conservation of megalithic heritage.
