A POSSIBLE AMPHORA FRAGMENT FROM 6TH CENTURY BALATONLELLE, WESTERN HUNGARY [EGY LEHETSÉGES AMPHORA TÖREDÉK A 6. SZÁZADI BALATONLELLÉRŐL] JF - ARCHEOMETRIAI MŰHELY J2 - ARCHEOMETRIAI MŰHELY VL - 21 PY - 2024 IS - 2 SP - 201 EP - 216 PG - 16 SN - 1786-271X DO - 10.55023/issn.1786-271X.2024-016 UR - https://m2.mtmt.hu/api/publication/34839820 ID - 34839820 AB - This study reports on a unique finding connected to the re-examination of the ceramic assemblage recovered from the Langobard age (6th century AD) settlement of Balatonlelle, situated in the territory of the former Roman province of Pannonia (now in western Hungary). An undecorated body sherd, not picked up by either the initial typological evaluation of the ceramics or by the preliminary petrographic analysis, was now reassessed by thin section ceramic petrography and scanning electron microscopy. The new analyses revealed that this sherd contains rock and mineral inclusions originated from ophiolites, including slightly serpentinised peridotite fragments. Such rocks do not occur on the surface in Hungary, whereas they are commonly found in the Eastern Mediterranean. The presence of ophiolites in the potsherd indicates that this vessel was produced in a distant territory. The macroscopic characteristics of the sherd combined with its petrographic fingerprint suggest that this pot might have been a transport amphora produced in the Eastern Mediterranean. Although rarely found in Pannonia in the Migration Period, several amphora types, including the most frequently found LRA 1 type, were produced in numerous production centres in the Eastern Mediterranean, in territories geologically congruous with the aplastic inclusions found in the fabric of the Balatonlelle sherd. The significance of this finding is that from Langobard age Pannonia, amphorae occur only sporadically, connected mainly to former Roman settlements. While any conclusions drawn from a single sherd must necessarily remain tentative, this sherd nonetheless provides some material evidence for the existence of some sort of contact between Balatonlelle and the Eastern Mediterranean during the 6th century, be it economic, political or cultural. This study also aims to celebrate the career of György Szakmány, who was one of the key figures to establish ceramic petrographic research and education in Hungary, and trained many generations of petrographers – including the present authors. As such, it also serves as an example how ceramic petrography can bring a new dimension of information to archaeological research.

The focus of this paper is on two mineralisations of this type (Kçira and Thirra) in the Mirdita Zone, an ophiolite zone representing the Mesozoic Neotethys Ocean in the Dinarides. Our aim is to understand the ore-forming processes and the genesis of these deposits, which can be used in future exploration projects. According to the petrographical analysis, the host rock suffered propylitic alteration or subgreenschist facies metamorphism. Mineral chemistry of pyrite and epidote suggests a VMS related origin, more precisely, the deeper part of its stockwork feeder zone. The bulk rock geochemical analyses confirms that the mineralisations are classified as mafic-, Cyprus-type VMS deposits. Differences in the geochemical compositions and the corresponding mineralogical observations are attributed to the distinct original geotectonic positions: higher amount of compatible elements (Cr, Ni, V and Cu) occur in Kçira, which formed in a mid-oceanic ridge environment, while incompatible elements (Ag, As, Co and Zn) are more abundant in the Thirra deposit, which formed in a supra-subduction zone setting.

The mineral cargo of dacitic pumices enables us to constrain the conditions of the pre-recharge crystal mush, the recharge magmas and the post-recharge magma prior to eruptions. A careful evaluation of the results yielded by various thermometers, barometers, oxybarometers, chemometers and hygrometers as well as direct comparison with experimental data were necessary to select the appropriate techniques and therefore to constrain the conditions for the Ciomadul magmatic system. Beneath the volcano, a felsic crystal mush body is inferred at 8–12 km depth comprising slightly oxidized (0.5–1.6 ∆NNO), low-temperature (680–750 °C), highly crystalline magma. This zone is underlain by a deep magma storage zone with less evolved, hot (> 900 °C) magma at 16–40 km depth. The dominantly explosive volcanism after the effusive eruptions (160–90 ka) can be explained by the ascent of distinct recharge magmas. They contained high-Mg (MgO > 18 wt%) amphibole, which could have crystallized from ultrahydrous (H 2 O > 8 wt%) magma at near-liquidus conditions. The rates of amphibole overgrowth and microphenocryst formation require weeks to months for the magma mixing and the eruption events. The hybridized melt became more oxidized and contained dissolved water in around 5.5 wt% at temperature of 790–830 °C calculated from the re-equilibrated Fe-Ti oxides. These magma properties along with the degree of crystallinity (27–38 vol% crystals) favored rapid magma ascent and an explosive style eruption. Thus, the strongly hydrous nature of the recharge magma in addition to the crystallinity and H 2 O content of the pre-eruption magma plays an important role in controlling the eruption style.
