Course Module: PF 120 – 2D Structural Model

2022-01-12T06:43:11-06:00

A Two-Dimensional (2D) Structural Model, a geophysical and geological based cross-sectional model of the earth, is best described in terms of its exploration objective. This means that when a geologic target is chosen, the s t ructural model is designed to represent the geologic/geophysical environment surrounding the prospective area. Learning Objectives: After completing this module, you’ll be able to: Describe what a 2D Structural Model [...]

Course Module: PF 121- 3D EarthModel

2022-01-12T06:43:23-06:00

A Three-Dimensional (3D) EarthModel, a geophysics- and geology-based three-dimensional model of the earth, is best described in terms of its exploration objective. Once a geologic target is chosen, the model can be designed to represent the geologic environment surrounding the prospective zone. Learning Objectives: After completing this module, you’ll be able to: Describe what a 3D EarthModel is. Describe how extensive should the model be. [...]

Course Module: PF 222- 3D Bouguer Correction

2022-01-12T06:43:36-06:00

The simplest type of Bouguer correction to gravity data is the slab correction which removes the gravitational effect of an infinite horizontal mass between the station elevation and an assumed datum. In many areas, that underlying mass is not a horizontal slab but has an undulating upper surface, or topography. For land or sea bottom surveys, the result is that the part of the mass [...]

Course Module: PF 236 – Crustal Model-Moho

2022-01-12T06:43:50-06:00

The boundary between the Earth's crust and the mantle has been defined as the Mohorovičić discontinuity or known for short as the Moho. This boundary interface involves a large change in both velocity measured directly using refraction data and density contrast measured using gravity data. Due to this contrast, undulations in the Moho surface generate anomalies of regional scale producing gravity gradients that can conceal [...]
