Abstract

Porphyritic Granite originated from Tampin, Negeri Sembilan, a distinctive igneous rock dating back to the Late Triassic (230 - 200 million years ago). It can be characterised by its texture featuring larger crystals known as phenocrysts embedded within a finer-grained matrix called the groundmass.

"Porphyritic" refers to the texture of the rock. In porphyritic granite, larger crystals, known as phenocrysts, are embedded within a finer-grained matrix called the groundmass. This contrast in grain size is a defining feature of porphyritic rocks.
