A new species and genus of Lower Jurassic rhynchonellide (Brachiopoda) from Livari (Rumija Mountain, Montenegro): taxonomic implications of the shell microstructure
A new rhynchonellide brachiopod genus and species, Skadarirhynchia semicostata gen. et sp. nov., is described from the late Pliensbachian of Livari, Rumija Mountain, southeastern Montenegro. It occurs in shallow-water brachiopod-crinoid packstone beds (bioclastic limestones) of the periplatform facies of the Dinaric Carbonate Platform. Stratigraphy is constrained by means of 87Sr/86Sr dating indicating a late Pliensbachian age, and by the fact that the brachiopod beds lie immediately below the Toarcian marly limestones, which is consistent with the regional stratigraphical position. ...Barbara V.

Recycled Carbonate‐Bearing Silicate Sediments in the Sources of Circum‐Mediterranean K‐Rich Lavas: Evidence From Mg‐Zn Isotopic Decoupling
Zi‐Tan Shu, Sheng‐Ao Liu, Dejan Prelević, Yu Wang, Stephen F Foley, Vladica Cvetković, Shuguang Li (2023)The high flux of subaerial volcanic CO2 emissions around the circum-Mediterranean region requires the involvement of an unusually carbon-rich reservoir, but the origin of which is still unclear. Here, we aim to resolve this problem by analyzing Mg and Zn isotopes for the widely distributed mafic potassic to ultrapotassic lavas in this region. These K-rich lavas have lower δ 26Mg but similar δ 66Zn compared to mid-ocean ridge basalts (MORB). No known magmatic processes can explain the isotopic data, ...Mg i Zn izotopski sistemi i njihovo razdvajanje, Circum-Mediteranske K-bogate lave, carbonatitski metasomatizam omotača, recikliranje sedimenataZi‐Tan Shu, Sheng‐Ao Liu, Dejan Prelević, Yu Wang, Stephen F Foley, Vladica Cvetković, Shuguang Li.
