2013 IGRF-Corrected Total Magnetic Intensity (TMI) ASCII data, Karonga Area, Northern Malawi, 9.69S-10.09S (2017, investigators Estella Atekwana, Jalf Salima, Leonard Kalindekafe)

IGRF-corrected Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of a larger country-wide airborne magnetic data set acquired by the Geological Survey Department of Malawi in 2013. This data was acquired with a flight elevation of 80 m along NE–SW lines with spacing of 250 m. The tie lines were oriented NW–SE and spaced 5 km apart. The data was gridded at 50 m cell size using a minimum curvature algorithm. The data set is cited in Kolawole et al. (2017) in which it was used as part of the project called "Active deformation of Malawi Rift North Basin hinge zone modulated by reactivation of pre-existing Precambrian shear zone fabric". The data file is in ASCII CSV format. Funding was provided by NSF award EAR 1009988. This data set is shared with other researchers for the purpose of research in Malawi only. The government of Malawi has to be acknowledged as the source of the data, and all research findings have to be shared with the Geological Survey Department of Malawi. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the Geological Survey Department of Malawi.

经国际地磁参考场（IGRF）校正的总磁强度（TMI）数据，覆盖马拉维北部卡龙加地区（纬度9.69°S–10.09°S，经度33.79°E–34.09°E）。该处理后的航空磁测数据集是马拉维地质调查局2013年获取的全国性航空磁测数据集的子集。数据采集参数为：沿东北-西南方向测线飞行，飞行高度80米，测线间距250米；联络线呈西北-东南走向，间距5公里。采用最小曲率算法以50米像元大小对数据进行网格化处理。该数据集被Kolawole等人（2017）引用，用于“前寒武纪剪切带构造复活调控下的马拉维裂谷北盆地枢纽带活动变形”项目。数据文件格式为ASCII CSV。本数据集由NSF资助（项目编号EAR 1009988），仅向从事马拉维相关研究的其他研究者共享。使用时需注明马拉维政府为数据来源，且所有研究成果需与马拉维地质调查局共享。有关数据采集参数的详细信息（如所用磁力仪传感器、采集日期、地球物理承包商等）可向马拉维地质调查局索取。
