Pemodelan Inversi Linier Least-Square (LS) Pada Anomali Geomagnet Model Dyke

Abstrak

Least-Square linear inversion modeling has been conducted on the dyke model geomagnetic anomaly. This study aims to obtain linear inversion modeling on the dyke geomagnetic anomaly. Dyke model's geomagnetic anomaly interpretation is done to anomaly the earth's magnetic field due to the magnetic properties of rocks that differ from one another. There are several types of ores such as magnetite, ilmenite, and phirotite carried by sulfide ore which produce distortion in the magnetism of the earth's crust, and can be used to localize the distribution of ore. Each magnetic anomaly observed above the surface can be evaluated by calculating the projection of the magnetic field anomaly. Based on the inversion that has been done, it can be concluded that the results of the inversion using the least-square method can follow the pattern of synthetic data results well and the results of the calculation of the linear inversion method LS without noise and using noise have the same parameter values. Where the rms error value is 0.0258.
