Abstrak: Kawasan kajian terIetak di Kuari (IJM), Labu, Negeri Sembilan. Berdasarkan kajian petrografi yang dilakukan didapati mineral utama yang membentuk batuan di kuari ini ialah kuarza, feldspar di samping mineral biotit serta klorit. Kandungan mineral kuarza melimpah iaitu melebihi 39%, feldspar kira-kira 25% manakala biotit dan kIorit masing-masing menunjukkan nilai sekitar 5% dan 2%. Batuan granit di kuari ini boleh dikelaskan kepada empat jenis kumpulan iaitu granit berbutir halus, granit biotit berporfiri berbutir kasar, granit biotit berbutir sederhana dan granit zon sesar. Berdasarkan hasil ujian mekanikal, sumber bahan aggregat daripada kuari ini mempunyai kekuatan yang tinggi.

 

Abstract: The study area is located at IJM Quarry, Labu, Negeri Sembilan. Based on the petrography analysis the percentage of quartz in the rock is higher than 39%, feldspar is about 25% while biotite and chlorite are 5% and 2% respectively. There are four groups of granite that have been classified such as fine-grained granite, coarse grained porphyritic biotite granite, medium grained biotite granite and fault zone granite. Based on the results of mechanical testing, aggregate resources from this quarry are considered to have high strength.
