Engineering properties of granitic soils and rocks of Penang Island, Malaysia

Abstract

The granitic rocks of Penang Island can be divided into two types, namely Type I (Sg. Ara) and Type II (Bt. Bendera), based on differences in age, mineralogy and texture of the rocks. These two types of granites and the soils derived from them exhibit soil mechanics, soil chemistry and rock mechanics properties which are rather different. Among the apparent differences: granitic soil I possesses high dispersion potential, while the dispersion potential for granitic soil II is low. Granite Type II shows strengthihardness which are higher compared to Granite Type 1. Nevertheless, there are also some similarities in the properties mentioned between the two types of granites.

Analysis of Geotechnical-Assisted 2-D Electrical Resistivity Tomography Monitoring of Slope Instability in Residual Soil of Weathered Granitic Basement

“…Bendera Type). Type I is of late carboniferous to early Permian in age, is medium-grained, and contains primary muscovite, while Type II is of Triassic age, is coarse-grained, and does not contain primary muscovite (Tan, 1994). Type I (Sg.…”

Correlation between Uniaxial Compressive Strength and Point Load Strength of Penang Island Granites

“…One of the main goals of this study is to build upon the work by [39] Through this, existing knowledge on the Penang Islan Granites can be improved. [39] proposed the upper and lower boundary lines for Penang Island Granites. As such, the upper boundary and lower boundary is compared for the overall samples.…”

Monitoring of the ground deformation in Penang Island, Malaysia using Permanent Scatterer Interferometry Synthetic Aperture Radar (PS-InSAR) and Ground-Penetrating Radar (GPR) techniques

“…Penang Island consists of coastal plains (situated on both the east and west coasts) and hills (running from the north to the south) with the geological settings shown in Figure 1b. The island's soil comprises residual soil formed by the untransported accumulation of organic material and graded beneath granitic soils (Tan, 1994;Yahaya et al, 2019). The granites have textural and mineralogical differences and compose a unique plutonic complex (Cobbing et al, 1986).…”
