| Description: |
Magnetic total field data were collected on a meadow close to the volcano Rockeskyller Kopf near Reckeskyll, West Eifel, Germany. The data were obtained with the proton magnetometer ENVI-MAG (Scintrex) and a laser tachymeter was used to determine the exact position of the measurement points. The measurements were carried out on four different days in spring 2011. No corrections were made for diurnal variations as the diurnal variations were negligible compared to the anomaly. The main objective of the study was to locate and model the potential eruption centre of the exceptionally large sanidine crystals that were found nearby. These crystals probably originate from phonolitic tuff and have formed in a highly differentiated magma chamber. ; The data was obtained using the proton magnetometer ENVI-MAG (Scintrex). A laser tachymeter was used to determine the exact position of the measuring points. The device was positioned at a reference point (ID 000) so that it was possible to survey the entire measurement area from this position and measure the measurement points. The locations were determined in cylindrical coordinates. And the reference point's location was determined using GPS.Due to wooded areas with undergrowth and bushes in the south-west of the study area, the measurements could not be carried out in the same way, as the visibility for the laser tachymeter was severely impaired by the vegetation. The laser tachymeter was therefore moved to a different position from which it was easier to see into the woodland (ID 500). In the woodland, the measuring points were taken as evenly as possible, as long as the laser tachymeter could determine the position. The measurements were done on four different days in spring 2011: 2011-04-11, 2011-04-16, 2011-04-17 and 2011-05-13. The diurnal variations were always significantly smaller than the anomaly signal. Therefore, no correction of the diurnal variations were applied to the data. ; The dataset provides for each measurement a unique ID (column 1); the position of ... |
