Is the study of crystal morphology really old - fashioned?

1998. in Toronto, on the 17th General Meeting of IMA, one of the goals was to encourage further studies of crystal morphology and it’s relation to the growing conditions as a part of mineralogical investigations in 21st century. What is the purpose of these morphological studies? This kind of investigation has irreplaceable value for better understanding of crystals and crystal growth. The explanation of this is presented by some examples. 1. Investigating morphology, one can investigated morphogenesis. For example, studies of barite and calcite from Krapinske toplice thermal spring in Hrvatsko Zagorje, Croatia where six generations of barite (fig. 1) were investigated in order of determining crystal genesis [1]. 2. Oriented coalesce is practically impossible to study in any other way but via morphological studies. Several oriented coalesces are described on minerals from Stari Trg - Trepča mine, Kosovo [2, 3, 4]. 3. Parallel-perspective drawings of crystals in addition with growth prints on crystal faces make possible the orientation of crystals. Very good examples of this are measurements of epidote crystals from Smilevski dol near Dunje in Macedonia [5]. 4. Using morphological measurements one should be in the possibility to acquire axis ratio which is the basic information about a crystal [5].
