Mapping Hydrothermal Mineral groups and Geological Structures in the Kirk range - Lisungwe Valley Area in Malawi using ASTER imagery data

Emmanuel Chinkaka, Francis Kapakasa, Chikondi Chisenga, Richard L.S Mvula, Wilson Tchongwe,

Remote sensing studies have recently been used to aid early stages of mineral exploration and lineament mapping. A multispectral remote sensing sensor known as Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used in this research as a main remote sensing data source. ASTER sensor measures reflected radiation in VNIR, SWIR...

Short Communication

The limitation of the gravity inversion method based on the Parker-Oldenburg algorithm in determination of the basement topography

Chikondi Chisenga, Emmanuel Chinkaka,

This short communication discusses a 2013 publication by Oruç et al., (2013) who presented a structural interpretation map of the Erzurum Basin in eastern Turkey using curvature gradient tensor, and inferred the basement topography using gravity inversion method. In our comment, we show the limitation of the gravity data they used and the flawed ap...

Banana bunchy top disease, caused by Banana bunchy top virus (BBTV), is a serious disease that affects the productivity of bananas globally. The disease is responsible for the current reduction of banana production in Malawi, and there are ongoing efforts to resuscitate the local banana industry. National surveys were conducted in 2020 and 2021 in...
