| EAGE Barcelona – Geosoft presents Paper |
You are invited to join Geosoft’s Gerry Connard as he presents, 3D Gravity and Magnetic Model of a Triassic Large Igneous Province Vent, Central Alaska Range, Alaska at the EAGE 2010. Thursday, June 17th at 15:20, Room 116.
Three-dimensional (3D) modeling of gravity and magnetic data shows details of the Amphitheatre Mountains structure, flood basalt thickness, and geometry of ultramafic sills. Modeling is based on a compilation of existing regional and newly-acquired high-resolution profile gravity data, a compilation of regional and high-resolution aeromagnetic surveys, and numerous rock-property data (including density, susceptibility, and magnetic remanence measurements of outcrops, hand samples, and drill cores).

Tools & Tips
1. How to set up duplicate information for your survey (location) geochemistry source file.
Duplicate sample identification has been simplified and improved. The Duplicate indicator column now contains the original sample number of the parent sample. This enables you to have multiple duplicates that reference a single parent sample. Click the link below to find out how.

2. How to create a Master Grid or Master Voxel.
Master Grid
The Master Grid utility lets you create a uniform grid of any size and coordinate system for Grid and Voxel Math operations. A Master Grid may also be used in GMSYS-3D for creating the Index Grid that defines the model.
Master Voxel
The Master Voxel utility allows you to create a uniform voxel of any size, orientation, and coordinate system. A Master Voxel can define the dimensions of the resulting voxel when resampling and completing voxel math operations.

3. Can I create sections from curved or crooked geophysical survey lines?
You can now create sections from survey lines that contain bends or curves. You can display these curved or crooked sections in 2D or 3D views as either grids or pixel plots. This new section support provides accurate geospatial representation by ensuring that data are correctly positioned along the survey line. These sections support full data linking between all displays of the data including: plan maps, sections and 3D views. This new support for sections is available as part of the montaj Geophysics extension 7.2.
