Paleocurrents
A paleocurrent or paleocurrent indicator is a geological feature (typically a sedimentary structure) that helps one determine the direction of flowing water in the geologic past. This is an invaluable tool in the reconstruction of ancient depositional environments. There are two main types of paleocurrent indicators: WebJun 30, 2024 · The structural analyses suggest that about 85% of the paleocurrents were from NE to SW direction with subordinate directions from WNW to ESE. Based on the predominant paleocurrent directions, the sediments were probably derived from the basement Birimian rocks (metavolcanic and metasedimentary rocks with associated …
