| dc.description.abstract | All geophysical methods, either in the exploration of natural resources or in the study of earth structures are related to the physical properties of rocks. Physical properties of the most commonly used in geophysical research are the property of elasticity, specific gravity (or density) and compressive strength. These physical properties are the basis for the interpretation of data collected from studies of geophysical research. The research has three objectives. Firstly, to study the physical parameters of Malaysia’s major rock in terms of property of elasticity, specific gravity or density and compressive strength. Secondly, to examine the relationship between all the physical parameters under investigation, and thirdly to form a table of physical characteristics of these three types of rock (granite, limestone and marble). All rock samples were collected from the North West peninsular Malaysia and three types of tests had been conducted which include method of ultrasonic testing, water displacement method, and point-load test. In general, all the results obtained in this study were validated statistically based on small ratio between mean and standard deviation. The study shows that the seismic P wave velocity, (Vp) is the highest in limestone rock than granite and marble. This result is supported by the specific gravity values which indicate that the limestone is denser than granite and marble. Correlations were made between the variations of Vp toward elastic constant. In general, there is a linear relationship between Vp with all the elastic constants and the relationship had been validated by the linear correlation coefficient, (r). Method of regression analysis was conducted to investigate the relationship between Vp Good correlation had been found in the limestone where V and all the elastic constants. Elastic constants involved are young modulus, (YM), shear modulus, (SM), bulk modulus, (BM), and lame constant, (LC). p were successfully correlated with the elastic constants and therefore, all the resulted regression equations can be used for future estimation due to the high coefficient of determination, (R²). Whereas for granite rock, only the correlation between Vp and BM had been successfully correlated with the acceptable R². While for marble rock, two correlations had been made which are Vp and BM as well as Vp and LC. Studies on the relationship between ratio of P wave velocity and S wave velocity, (Vp/Vs) towards the elastic constant shows that there are effective relationships between the ratio of Vp/Vs and LC for all rock samples based on the high value of R². Overall, this study had successfully investigated the physical properties of rocks (the property of elasticity, specific gravity or density and compressive strength) of the major rocks in North West peninsular Malaysia. | en_US |
