Abstract

At the request of the Director, Geological Survey Department of Selangor/W. Persekutuan, two geophysical surveys using regional gravity and transient electromagnetic (TEM) techniques were carried out at Hulu Langat area and Sg. Serai, Selangor. The objectives of the survey were to delineate major geological structures that may be associated with the occurrences of the hot springs in the area. The regional gravity survey detected two major faults along part of Sungai Langat and Sungai Semenyih. These faults created a fractured zone. This fracture zone provided a conduit for the hot spring to seep through. The TEM results indicate the presence of two conductive zones which are attributed to fractures within the bedrock. Future physical development at the sites should be implemented away from these conductive zones to avoid potential interference to these structures which have been identified as the pathways of the hot springs.
