Block modeling of rho data could be conducted to obtain the three dimension distribution of rho value. Research was conducted on Gunungsari Hill in Magelang, Central Java Indonesia. The main purpose of this research was for proving that two dimensional rho data can be modeled into block model while they were crossed.
Rho data was obtained from ten boreholes on the peak of Gunungsari Hill. Each borehole coordinate was plotted on Rockworks software. Block model was created by interpolating rho data on boreholes within Anisotropy Inverse-Distance Algorithm.
Interpolation of two dimensional rho data from crossed boreholes lines formed block model. Crossed lines acted as planes in four directions those formed blocky shaped model. Making rho block model with crossed boreholes lines is recommended for project with limited funding.
