Rock is a naturally occurring substance. The study of rock properties and its mineral composition have many useful information and benefits, such as for building construction and aggregates. Understanding of how rock material was formed will reveal how it can be used in a building, its limitations and how it will weathered over time. The research objectives are to categorize the rock properties based from the methods of geophysics, geotechnical and petrography analysis, and to identify the possibility of the material used for construction purpose. The location of the study is at Bukit Chondong, Beseri, Perlis, Malaysia. The study was conducted using 2-D resistivity method, geotechnical test and thin section analysis. For 2-D resistivity method, the length of a single survey line is 40 m with minimum of 1 m electrode spacing and the array used was Pole-dipole. For geotechnical test, there are two test conducted on the core samples of mudstone and sandstone, which are permeability test and porosity test. Finally, the core samples was analysed from thin section to observe the shape and sorting of the grains. The result was tabulated, where mudstone has low resistivity compare with sandstone, which are less than 170 Ωm and 200 to 2000 Ωm respectively. The value of permeability for sandstone is high compare with mudstone, which is 4.48 and 0.883 (x10-22 m²) respectively. However, sandstone has low percentage of porosity (0.9 %) compare with mudstone (1.6 %). By comparing both types of rocks in this area, sandstone has high resistivity, high permeability and low porosity, while mudstone has low resistivity, low permeability and high porosity giving sandstone and mudstone are suitable material for construction and aggregates. The methods of geophysics, geotechnical and petrography analysis successfully identify the rock properties. [ABSTRACT FROM AUTHOR]
