Location: Padang Light granite is quarried near Jinjiang, Fujian province, China. There are many different quarries all producing slightly different shades however graining is usually consistent.
Description: Padang Light granite is a fine-grained, medium grey biotite trondhjemite of the Precambrian period. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a granite.
A small sample of Padang Light granite is usually representative not having a wide variation in colour and veining however swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Padang Light granite is frost free and polish constant.

Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
Trondhjemite: A leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites. Trondhjemite is common in Archean terranes occurring in conjunction with tonalite and granodiorite as the TTG (tonalite-trondhjemite-granodiorite) orthogneiss suite.
