Geochemical characteristics of the granitic rocks from Boundary Range Batholith, Peninsular Malaysia

Geochemical characteristics of Boundary Range granite are similar to those of the Eastern Belt Granite and not to those of the Western Belt Granite. Although, the majority of the rocks from the Boundary Range granite have Si02 contents (> 65% SiO) similar to those of Western Belt granite, other elements such as pp" Nap, Ba and Sr are very different. The Boundary Range granite can be classified as T type granite as the granite has high Nap content, abundance of mafic microgranular enclave, contain sphene and hornblende and increasing ACNK values with SiOr Simple modeling of the granite using log-log Ba vs Sr plot suggest that plagioclase, K-feldspar and biotite are important crystallisation phases in the magmatic evolution.
