Bukit Choras is one of the temple sites of Ancient Kedah a port-polity centred in the Bujang Valley which flourished between the 2nd to the 14th Century C.E. Being located in isolation far to the north of the other sites of Ancient Kedah the study area has rich cultural heritage value according to the recorded history. Previous surveys on the site had led to the discoveries of Buddhist structural remains as well as artefacts dated back to the 7th Century C.E. Aside from the ancient architectural features visible from the surface there are potential for more structural remains being buried beneath the surface. This paper presents 2D electrical resistivity imaging to investigate the shallow subsurface characteristics at the archaeological site of Bukit Choras Kedah Malaysia. The study identified the subsurface was consisted of two main zones; low resistivity zone with a depth of 2 to 3 m and resistivity range value of 100 to 500 Ohm.m surrounded by high resistivity zone with a range value of 500 to 3000 Ohm.m. This low resistivity zone is interpreted as a high conductivity zone and it is interpreted as laterite material which is derived from parent rock. This laterite material is made up of rich iron and aluminium contents. In addition this low resistivity zone also interpreted as a potential zone in archaeology perspective. This is supported by the visible evidence on the Earth surface of the study area where laterite as local material is used for the Buddhists worship structure before the coming of Islam in Kedah Malaysia.

Abstract

Bukit Choras is one of the temple sites of Ancient Kedah a port-polity centred in the Bujang Valley which flourished between the 2nd to the 14th Century C.E. Being located in isolation far to the north of the other sites of Ancient Kedah the study area has rich cultural heritage value according to the recorded history. Previous surveys on the site had led to the discoveries of Buddhist structural remains as well as artefacts dated back to the 7th Century C.E. Aside from the ancient architectural features visible from the surface there are potential for more structural remains being buried beneath the surface. This paper presents 2D electrical resistivity imaging to investigate the shallow subsurface characteristics at the archaeological site of Bukit Choras Kedah Malaysia. The study identified the subsurface was consisted of two main zones; low resistivity zone with a depth of 2 to 3 m and resistivity range value of 100 to 500 Ohm.m surrounded by high resistivity zone with a range value of 500 to 3000 Ohm.m. This low resistivity zone is interpreted as a high conductivity zone and it is interpreted as laterite material which is derived from parent rock. This laterite material is made up of rich iron and aluminium contents. In addition this low resistivity zone also interpreted as a potential zone in archaeology perspective. This is supported by the visible evidence on the Earth surface of the study area where laterite as local material is used for the Buddhists worship structure before the coming of Islam in Kedah Malaysia.
