Abstract

Analiziran je uzorak pijeska Golubovec formacije iz egera prikupljen na lokalitetu Vinagora u Hrvatskom zagorju. Mokrim sijanjem ustanovljeno je da je riječ o vrlo loše sortiranom pijesku sa značajnim udjelom lutitnog materijala. Udio karbonatne komponente utvrđen kalcimetrijom vrlo je malen. Analizom teške i lake mineralne frakcije ustanovljeno je da većina čestica pijeska potječe iz metamorfnih stijena, primjerice gnajsa, škriljavca ili sijenita. Najzastupljeniji teški minerali su granat, turmalin, kromit, titanit i apatit. Pijesak je alteriran. Transport nije bio dug i vjerojatno nije bilo pretaloživanja. Taloženje se najvjerojatnije odvijalo u relativno niskoenergetskom marinskom ili eventualno prijelaznom okolišu.

Abstract (english)

The sand from Egerian Golubovec formation is sampled at the Vinagora site in the area of the Hrvatsko Zagorje. Using the wet sieving method, the sand is determined as very poorly sorted with a significant stake of lutite material. The share of the carbonate component calculated with calcimetry method is minor. After the conducted analysis of heavy and light mineral fraction it is established that majority of the sand grains originate from metamorphic rocks such as gneiss, schist and syenite. The most common heavy minerals are garnet, tourmaline, chromite, titanite and apatite. The sand is altered. Transport was not long and resedimentation probably did not occur. Sedimentation most likely took place in a relatively low-energy marine or eventually transitional environment.
