Popis: Pekan, Pahang is generally covered with unconsolidated Quaternary alluvium as it makes up the Pahang Delta. Well studies have shown that the underlying metasediments and volcanic basement of Pekan are shallow, with increasing depth towards the shoreline. However, the structure of the basement is still unknown due to the poorly distributed wells throughout the Pekan district. Thus, the Transient electromagnetic (TEM) survey was conducted to provide a better data coverage by measuring the basement rock electrical conductivity. 300mS/m was set as the threshold value in filtering the conductivity values. These values are then used to create a 2D pseudo section along the profile A-A’. The pseudo section has revealed that the depth of the basement conforms the boreholes data in Pekan despite having an irregular structure along the profile. The conductivity value of the Pekan basement rock is found to be approximately 37.5 mS/m which matches the range of weathered granite value.
