Tokom aprila bavili smo se prikupljanjem i proučavanjem literature, vršenjem priprema i planiranja terenskog istraživanja. Zbog nepovoljnih vremenskih uslova, prva posjeta kamenolomu i terenska istraživanja su odgođeni za polovinu maja.During April members of our team were collecting and studying literature, doing preparations and planning field work. Since the weather conditions were not suitable, our first visit to quarry and field work are delayed for the middle of May.
