NUMERICAL DATA EXTRACTION AND EVALUATION OF GRAIN SHAPE FACTOR USING LASER DIFFRACTION METHOD - CASE STUDY FROM SZCZECIN LAGOON, NORTHERN POLAND
Abstract
The laser diffraction (LD) is one of the most widely applied grain size measurement methods. The main advantages of LD are: (1) relatively short time of single measurement, (2) low cost of analysis, (3) simplicity of sample preparation, (4) great amount of acquired numerical data. One of the less frequently obtained parameters, often provided only by application of dedicated external hardware, is so-called ?elongation parameter?, ?grain shape factor? or ?grain shape parameter?. Due to the inability of direct export of numerical grain shape data from the Malvern Hydro Sight camera, authors proposed own method of digitalization and recalculation of grain shape graphs produced by the Malvern software. Acquired sedimentological and geochemical data were analysed using statistical methods, such as correlation/regression analysis and principal components analysis (PCA). Proposed method of data extraction and analysis of grain shape parameters may be especially useful tool during investigation of Quaternary sediments and reconstruction of environmental changes.
