“…The analysis of volcanic rocks in the study area indicates that the pressure‐temperature conditions of crystallization for amphiboles and clinopyroxenes are consistent with the presence of a secondary magmatic reservoir at a wide range of depths (Kovacs et al., 2021). In particular, the lavas formed at the peak volcanism at 9–11 Ma would require both deep (20−33 km) and shallow (2−5 km) magmatic chambers.…”

“…At the depth of 2–7 km, two electrically resistive anomalies of resistivity of 100–300 Ωm correlate with high positive magnetic anomalies of 200 and 600 nT (Figure 11). We interpret these anomalies as cooled magmatic intrusions, potentially associated with magmatic chambers that have given rise to calc‐alkaline lavas at the surface (Kovacs et al., 2021).…”

“…In particular, the lavas formed at the peak volcanism at 9–11 Ma would require both deep (20−33 km) and shallow (2−5 km) magmatic chambers. Both, shallow igneous bodies and a lower crustal mush zone (Kovacs et al., 2021), could contribute to the elevated geothermal heat flow of the Baia Mare region (80−100 mWm −2 ; Demetrescu & Andreescu, 1994; Lenkey et al., 2002). Lenkey and Surányi (2006) reported a high radioactive heat production for rhyolitic and dacitic lavas (2.7 × 10 −6 Wm −3 ).…”

“…In the study area, the volcanism was mainly composed of basalts and andesites with some more felsic varieties. The magma emplacement occurred between 15 and 7 Ma (Kovacs et al, 2013(Kovacs et al, , 2021Seghedi et al, 1998).…”

The Carpathian belt is one of Europe's major metallogenic provinces, where magmatic ore mineralization is associated with the past subduction environment. The upper crust is mapped for the first time in the Northeast Carpathian Volcanic Arc using magnetotelluric data inversion. The obtained 3‐D electrical resistivity model is interpreted in conjunction with geological information and magnetic anomaly data. The model illustrates the deep magmatic plumbing system including kilometer‐scale plutonic bodies at a depth of 2–7 km. The model implies that the transport of magma and fluids in the uppermost crust was controlled by pre‐existing faults and décollement horizons. Present ore mineralization, mined since historical times, can be attributed to an electrically conductive conduit that is mapped from the surface to a depth of about 30 km. It is suggested that this conduit connected a shallow magmatic chamber to a deep source region in the southeast during late Miocene time. An observed northwest deflection of the deep magmatic conduit at a depth of more than 10 km may explain the spatial gap in the distribution of the Miocene volcanic activity along the Eastern Carpathians.

“…A complex intermediate (mostly andesitic) multiphase volcanism developed in the 13.4-7.0 Ma time interval, consisting of four volcanic stages [17]. The complex evolution of the intermediate volcanism reflects the intricate volcano plumbing systems recently constrained for some relevant volcanic structures [18]. The first two volcanic stages were the most voluminous, including numerous volcanic complexes with overlapping products of the coeval volcanic centers.…”

The Neogene–Quaternary volcanic range running along the East Carpathians in Romania, extends from the Oaș Mountains, in the north-west, to the South Harghita Mountains and the Perșani Mountains, in the south-east, as part of the broader volcanic province of the Carpathian–Pannonian Region. It resulted from intense volcanic activity during the 15–0.1 Ma time interval, generating huge volumes of effusive and explosive products and a variety of volcanic edifices and primary landforms from large composite volcanoes to small-sized domes/dome-coulées/lava flows and volcaniclastic plateaus around them. The present-day landforms were shaped by various syn-volcanic deformation processes (such as volcano spreading), post-volcanic erosion of various degrees and types (including glacial erosion on the highest-elevation parts and relief inversion in the peripheral areas) and modern anthropic intervention. Developed on this diverse volcanic substrate, the present-day landscape shows a large variety of aspects due to further factors (original topography, elevation, vegetation cover, distance from settlements, anthropic activities, and degradation processes). This volcanic range hosts many geoheritage-relevant sites of various spatial extent (from hundreds of km2 to limited areas of a few 10 m2) and of protection status (from national parks, natural or scientific reserves, natural monuments, and protected areas to areas with no protection at all). Despite its high geoheritage potential, geoparks are still absent, geotrails are sparse, and geotourism is in its infancy in the East Carpathian volcanic range.
