Metode Dekonvolusi Euler Untuk Mengestimasi Kedalaman Sumber Anomali Gravitasi di Glass Buttes, Lake Country, Oragon

Abstract

This study will discuss the depth of the source of the anomaly in the gravity data. The method used is the Euler deconvolution method which is used to map the depth position of the source of gravity anomaly using a simple structural index. This research aims to test the Euler Deconvolution method to determine the source of the anomaly using synthetic data and apply it to field data. This research begins by making four synthetic data that have different forms and conditions. The structural index used is 0 for thin sheet edges and 1 for thin bed faults. Then, the field data used in this study is opensource data in the Glass Buttes area, Lake Country, Oragon. The Euler deconvolution method which has been tested on synthetic data shows that this method can be used to determine the position and depth of the source of the anomaly, especially at the top position and there is a limit to the Euler solution where to find a deep depth position, a larger area or grid is needed compared to the Euler deconvolution method. looking for a shallow depth position. The application of Euler Deconvolution to field data resulted the average depth of the fault structure to the west of the study area (area A) is 2,860 km, to the west of the study area (area B) is 2,619 km, to the north of the study area (area C) is 2,214 km, to the southeast of the study area (area D) is 2,536 km and to the east of the research area (area E) is 2,214 km.
