A research has been done to determine the rock sequences and to map the distribution of iron sand in the Jangka District, Bireuen Regency, Province of Nanggroe Aceh Darussalam. Geographicly, the area of research located at 5o 15' � 5o 16' LU dan 96o 48' � 96o 52' BT. The survey had been conducted between 15th � 22th November 2011. This research was used by Schlumberger configuration of geoelectric resistivity sounding method. Meanwhile, the main tool on this research was Resistivitymeter Naniura type NRD 22S. The field data was proceeded by using Progress Version 3.0 thus gathered informations such as the number of layer, the rock�s resistiviy value, and the sequence�s thickness. Furthermore, based on the information, a 3D reconstruction model of the survey was generated. The resistivity value classified into four layers. The first layer has value that varied by the thickness of 0.40m � 6.50m, consisted of soil and alluvial deposits. The second layer has thickness between 0.80m � 10.63m with the resistivity value varied between 0.13Ωm � 2.87Ωm, consisted of iron sand. The third layer has thickness between 1.10m � 32.00m with the resistivity value varied between 0.90Ωm � 9.92Ωm, consisted of sandstone. The fourth layer has thickness between 5.60m � 37.00m with the resistivity value varied between 0.020Ωm � 1.60Ωm, consisted of clay. The 3D model shows that the volume of the iron sand deposits on the area is 44.60 million m3.
