Abstract

Interpretasi kuantitatif pada penyelidikan geomagnet bertujuan untuk mengkonversikan anomali medan magnet dalani bentuk dish ibusi struktur batuan bawah permukan bumi. Telali dibuat program untuk meiuodelkan dan menghitung parameter-parameter struktur dike dua dimensi daerah Tulungagung dan sekitarnya dengan menguna.kan bahasa pemrograman Turba Pascal versi 7.0. Proses perhitungan dilakukan dengan mencocokkan antara kurva anomali lapangan dengan kurva anomali teoretis. Pencocokkan kurva dioptimasi dengan menggunalcan metode opfimasi Powell secara iteratif Hasil perhitungan menunjukkan baliwa struktur dike dua dimensi daerah Tulungagung dan sekitarnya merniliki parameter-parameter kedalaman antara 1368,165 — 2988,007 m, lebar antara 3262,701 — 13894,898 m, kemirin§an antara 31,819° — 166,563°, dan suseptibilitas antara 11317 x 10-6 — 44364 x 10 emu. Quantitative interpretation of geomagnetic survey has a purpose to convert field magnetic anomalies became distribution stone mass structure under ground form. It has been made software to build models and measurement parameters of two-dimension -dike structure at Tulungagung and sutTounding area by using Turbo Pascal version 7.0_ Matching between field anomaly curves with theoretical anomaly curves has done measurement process. Matching curves were optimized by Powell optimization method itteratively. The result of these measurement show that two-dimension dike structure at Tulungagung and surrounding area has depth parameters between 1368,165 — 2988,007 m, width between 3262,701 — 13894,898 m, dip between 31,819° — 166,563°, and susceptibilities between 11317 x --44364 x 10- emu.
