Otočić Jabuka (Scoglio Pomo; Scoglio del Pomo), Splitsko-dalmatinska županija, Hrvatska


Uninhabited volcanic islet in the Adriatic Sea, about 50 km northwest of the island of Vis (Lissa). The closest land masses are the small island of Svetac (also known as Sveti Andrija in Croatian and Sant'Andrea in Italian) and the islet of Brusnik. Jabuka islet (‘Apple’ in English, Scoglio Pomo in Italian) consists of a hundred meter (97 m) high, dark unfriendly pyramid with no place to land or embark on a boat or vessel (surface area ~0.02 km2). It administrativelly belongs to the municipality of Komiža (Comisa).

Kišpatić (1892), the first to study systematically igneous rocks from the islands, confirmed the similarity of the Jabuka rocks with those from Brusnik islet. By visual inspection and microscopic examination he revealed the mineral composition as plagioclase, augite, “iron ore” (= magnetite), “titanium ore” (=ilmenite) and apatite. Amphibole, biotite and chlorite originated by alteration of primary magmatic minerals. Kišpatić named the rocks of Jabuka augitic diabase. The large quantity of magnetite on both islets produces magnetic anomalies, what explains the difficulties in compass navigation in their vicinity.


Because of their texture, Jabuka and Brusnik rocks have been commonly interpreted as intrusives, and classified as augite diorite (Foullon, 1883; Viola, 1894; Michel, 1916); diorite (Pelleri, 1942), and augite albitite (Raffaelli, 1977). Several authors recognized an ophitic texture in these rocks and classified them as diabase (Martelli, 1908; Schubert, 1909; Cumin, 1921). In a comprehensive work on the igneous rocks from Vis, Jabuka and Brusnik, Golub & Vragović (1975) distinguished two main groups: a) sub-volcanic types with augite diabase; b) extrusive types with augite andesite, spilite-keratophyre and spilite. The first group characterizes Jabuka and Brusnik, whereas the second one is found on Vis. The parent magma is, however, the same. Greenschist-facies submarine hydrothermal metamorphism affected the whole rock during their consolidation, producing albite–chlorite–prehnite–uralite–quartz overprint. A system of open fissures and cracks was filled by secondary minerals of the prehnite–pumpellyite group (Balić-Žunić et al., 1990).

The first radiometric dating, and detailed mineralogical and geochemical study was done on the Jabuka Island rocks by Balogh et al. (1994). The Jabuka rocks are represented by an intrusion of two-clinopyroxene medium-grained gabbro, which derived from the crystallization of a slightly differentiated sub-alkaline magma. The average K/Ar age is 205 ± 6.9 Ma, and two isochrones gave 200.3 ± 7.9 and 199.5 ± 11.9 Ma with little amount of excess radiogenic Ar. It roughly reflects the latest stage of crystallization after intrusion. Analyzing plagioclase separates of Jabuka and Brusnik rocks, De Min et al. (2008) obtained new Ar/Ar plateau ages of 227 ± 5 Ma and an isochron of 226 ± 3 Ma for Jabuka, and plateau age of 226 ± 3 Ma for Brusnik. So the age is “shifted” toward the Middle Triassic, which is a better fit to the general rifting conditions in the area.
Recent inspection and research of the Jabuka and Brusnik intrusives (Palinkaš et al., 2010) revealed several novel discoveries, regarding presence of felsic dykes, pinkish in colour, which cut the intrusives for tens of meters. Thickness of these dikes is 10 to 30 cm. On Jabuka and Brusnik islands, they are characterized by the presence of well-developed crystals of potassium feldspars. The dykes are a product of melt fractionation, and the coarse-grained, micropegmatitic texture suggests crystallization below a subvolcanic level. A number of secondary minerals (albite, uralite, epidote, prehnite, pumpellyite, fibrous hornblende, etc.) produced by hydrothermal alteration, as well as the presence of fluid inclusions in albite, confirms, however, engagement of sea water in the magma solidification and spilitization. Results of the chemical analyses done on the Jabuka and Brusnik gabbro and K-rich dykes that were affected by hydrothermal processes can hardly be taken as a reliable discrimination criteria due to intensive spilitization. Biotite from the Jabuka gabbro gives a plateau age of 273 ± 1.1 Ma, with loss of Ar on 77.2 ± 2.4 Ma. K-feldspar from the Jabuka gabbro is unaffected and shows similar value of 269.4 ± 2.3 Ma, but K-feldspar from the dyke on the Jabuka is dated at 254.5 ± 2.0 Ma. Biotite in the Brusnik dolerite is dated at 265 ± 1.1 Ma, while K-feldspar has plateau age of 214 ± 0.9 Ma, obviously lowered due to release of Ar, during some later thermal episode. K-feldspar separated from the basalt-andesitic fragment in the volcanics from Komiža, Vis island, gave a of 276.6 ± 1.7 Ma age coherent with that of the other magmatic formations. The ages determined on biotite are more consistant and differ from those obtained on K-feldspars, which was the object of the previous datings. This explans why the former K/Ar and Ar/Ar dating gave ages, which are not completely compatible with the geotectonic events in the early history of Tethyan evolution (Upper Permian ages correspond to the early intra-continental rifting).

The gabbro of Jabuka is a phaneritic, medium-grained rock with sub-hypidiomorphic texture. Plagioclase and two pyroxenes (augite and pigeonite) represent the main phases with subordinate amphibole (uralite), biotite, Ti-rich magnetite, ilmenite in decreasing order of abundance. Plagioclase mostly shows an oscillatory zoning, ranging from An57 Ab41 to An75 Ab23. Flakes of sericite largely occur within the plagioclase crystals. Pyroxenes are mostly represented by pale-green unzoned augites and minor colourless magnesium pigeonite (En 57–59%). Uralitization converted pyroxenes to ferroactinolitic hornblende. Chlorite and fibrous secondary amphibole are a product of late-stage hydrothermal alteration (Balogh et al., 1994). The trace elements and normalized-MORB incompatible element spider diagrams support the similarity of the Jabuka gabbro with continental tholeiitic magmas, and exclude MORB-type affinity.
