Phosphateis one of minerals whichconsist ofP2O5 compound. Phosphatedepositscan be
foundall overPati, namely in Mount WatuKendong–Mount Gledegespecially inthree
districts, those are inSukolilo District, KayenDistrict, and Tambakromo District. Phosphates
can be found on outcrops of limestone walls and go into veins of limestone. To know more
about existence of phosphate in limestone, it needs to conduct lab tests using geophysical
method. This research is ageophysicalstudyofthe physicalmodelling utilizinggeoelectric
resistivitymethod. This research has apurposetoidentifythephosphatethroughphosphate

configuration.In this research,limestonerock and limestone rocks containing phosphate were
alternately planted in the soil and measured by using geoelectric of pole-pole configuration
method. The data obtained wereprocessed by usingsoftware called Res3Dinv. The results of
the soil research showedthatthe researchbeforeplanting the rock, the resistivity is 2.4 Ωm–
195 Ωm. The soil researchafterplantinglimestonerock showed that the resistivity of the soil
is 9.3 Ωm–591 Ωm, which resistivity oflimestonerocks is 591 Ωm. Another soil research,the
resistivity of the soil afterplantinglimestonerocks containing phosphate is 5.3 Ωm –255 Ωm,
which resistivity oflimestonerock containing phosphate is 255 Ωm and the resistivity of
phosphate is 147 Ωm.
