Determination of Mechanical Properties of Altered Dacite by Laboratory Methods
This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ...... mass strength parameters allows us to determine the influence of rock material heterogeneity on the values 0,; UCS | ¢;!%, and constant m;. Obtained 7 ,;!* and constant m; dependences define more reliable rock material strength parameter values, which can be used, along with rock mass classification systems ...

Pokazatelji recentne tektonske aktivnosti u speleološkim objektima Dževrinske grede (istočna Srbija)
Ana Mladenović, Jelena Ćalić (2022)Sistem Timočkog raseda predstavljen je sistemom desnih transkurentnih raseda generalnog pružanja sever – jug, koji su bili aktivni u periodu oligocena i miocena u okviru Karpato-balkanskog orogena. Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km.
