| Summary: | Middle Miocine - Pliocene (13.82-2.58 million years ago)
The granodiorite boulder is visually striking rock composed of minerals like quartz, plagioclase feldspar, biotite, and hornblende. It has a porphyritic structure with larger crystal (phenocryst) within a finer- grained matrix (groundmass), reflecting a complex crystallization process. This rock has fascinating geological history spanning from the Middle Miocene to the Pliocene, approximately 13.82 to 2.58 million years ago |
