Abstract

Abstract Pekalongan Residence has a relatively many sand and gravel deposits particularly in river area. Nowadays, many locations have been exploited by local residences or investors from other regions. Even though the exploitation has running, up to now the local government doesn’t know yet how many reserve indication material deposits in that area. As the result of that condition, it is called for the research to determine the potential of mining resources in river area. The factors estimate the mining potential based on geologic conditions such as elevation and deposit types. This research use grid and trapezium method. Based on laboratories tests showed that the dominant materials in that area is up to sand size(around 87 – 98%). The potential of deposits is divided into three i.e. river part, levee part and land part. The total of potential in each district are Kesesi (515.625 m3), Kajen (78.295m3), Karanganyar (1.938.751m3), Wonopringgo( 1.334.375 m3), Doro( 1.984.375 m3), Talun( 1.355.625 m3), Karangdadap( 140.150 m3) and Kedungwuni( 130.000 m3). Key words : reserves material deposits, sand and gravel deposits
