An unsupervised method of LIBS dataset clustering was proposed. Prior to the calculation no information about the dataset has been provided. LDA has been used as a verification tool for the particular partitioning algorithm. Estimation of credible number of PCs in correspondence to their variance was proposed. The superiority of cosine distance measure for high dimensionality data was proven.
