| 1. | It was discovered by a magnetic survey and a gravity survey.
|
| 2. | Costing, the HGSS can conduct magnetic, spectrometric and gravity surveys.
|
| 3. | A new gravity survey suggests how water from the south once found its way to the northern basin.
|
| 4. | They are used in gravity surveys over large areas for establishing the figure of the geoid over these areas.
|
| 5. | This may involve correcting the data for unwanted variations; for example, a gravity survey would be corrected for surface topography.
|
| 6. | Little Cornwallis Island was the home to Polaris Mine, the most poleward base-metal gravity survey in 1970 detected a large anomaly.
|
| 7. | In 1910 he graduated in civil engineering in Delft . The same year he started working for the Dutch gravity survey.
|
| 8. | Gravity surveys aim to detect significant accumulations of lead and zinc due to their greater density relative to their surrounding host rocks.
|
| 9. | One reason for caution is that a detailed gravity survey was unable to resolve whether the Olympia structure is, or is not, a fault.
|
| 10. | After the approval, ERHC began using a series of convertible notes to fund a magnetic / gravity survey and a 2D seismic acquisition program.
