Abstract

U ovom radu analizirani su dijabazi Vrličkog i Sinjskog polja, točnije s lokaliteta Garjak i Slane stine. Radi se o dijabazima čija starost do sada nije radiometrijski utvrđena, ali se pretpostavlja da pripadaju permotrijaskoj vulkanskoj aktivnosti zabilježenoj u širem području. Optičkim istraživanjem, te primjenom analitičkih metoda rendgenske difrakcije na prahu i infracrvene spektroskopije određivane su mineraloške i petrološke karakteristike uzoraka te su proučavani alteracijski procesi kroz koje su prošli. Utvrđeno je da se na oba lokaliteta radi o istom izvornom tipu stijena, koje se razlikuju po prisutnosti i intenzitetu alteracija. Utvrđene su niskotemperaturne hidrotermalne alteracije (albitizacija, sericitizacija, kloritizacija, kalcitizacija, prehnitizacija i epidotizacija) koje su na uzorcima lokaliteta Garjak izraženije, dok su na uzorcima lokaliteta Slane stine manje izražene.

Abstract (english)

In this work, the diabases of Vrličko and Sinjsko Polje, specifically from the localities of Garjak and Slane stine, were analyzed. These are diabases whose age has not been determined radiometrically so far, but it is assumed that they belong to the Permotriassic volcanic activity recorded in the wider area. The mineralogical and petrological characteristics of the samples, and the alteration processes they went through were studied by optical research and the application of analytical methods of X-ray powder diffraction and infrared spectroscopy. It was established that both localities are of the same original rock type, which differ in the presence and intensity of alterations. Low-temperature hydrothermal alterations (albitization, sericitization, chloritization, calcitization, prehnitization, and epidotization) were determined, which are more pronounced in the samples from the Garjak locality, while they are less pronounced in the samples from the Slane stine locality.
