Spatio‐temporal changes of upper mantle structure play a significant role in generating and maintaining surface topography. Although geophysical models of upper mantle structure have become increasingly refined, there is a paucity of geologic constraints with respect to its present‐day state and temporal evolution. Cenozoic intraplate volcanic rocks that crop out across eastern Australia provide a significant opportunity to quantify mantle conditions at the time of emplacement and to independently validate geophysical estimates. This volcanic activity is divided into two categories: age‐progressive provinces that are generated by the sub‐plate passage of mantle plumes and age‐independent provinces that could be generated by convective upwelling at lithospheric steps. In this study, we acquired and analyzed 78 samples from both types of provinces across Queensland. These samples were incorporated into a comprehensive database of Australian Cenozoic volcanism assembled from legacy analyses. We use geochemical modeling techniques to estimate mantle temperature and lithospheric thickness beneath each province. Our results suggest that melting occurred at depths ≤80 km across eastern Australia. Prior to, or coincident with, onset of volcanism, lithospheric thinning as well as dynamic support from shallow convective processes could have triggered uplift of the Eastern Highlands. Mantle temperatures are inferred to be ∼50–100°C hotter beneath age‐progressive provinces that demarcate passage of the Cosgrove mantle plume than beneath age‐independent provinces. Even though this plume initiated as one of the hottest recorded during Cenozoic times, it appears to have thermally waned with time. These results are consistent with xenolith thermobarometric and geophysical studies.

“…From the point when the FlN magma separated from its garnet-bearing source, it must have ascended rapidly through the lithosphere in order to keep the mantle xenoliths entrained within the rising magma. Already, the appearance of mantle xenoliths points to a fast ascending magma (Jordan et al 2014). A simple minimum ascent rate for the FlN magma can be calculated from the settling velocity (V s ) of the mantle xenoliths.…”

increase in quartzitic fragments from ~35 to <60 % with increasing stratigraphic height in the FIN deposits further indicates that the crater area successively widened during the eruption, which resulted in an increased recycling of quartzitic fragments. This eruption scenario, with the formation of a diatreme at depth, is also consistent with the absence of layers dipping inwards into the crater area.

“…These included monogenetic volcanoes sensu stricto and complex monogenetic volcanoes with multiple eruptive episodes, which in some cases are characterized by a complex magmatic feeding system. In the literature there are numerous examples for such eruptive behavior: Crater Hill [32], the long-lived scoria cone and lava flow complex of Rangitoto Auckland volcanic field, New Zealand [86], and Motukorea tuff ring in Auckland volcanic field, New Zealand [87,88]; the Kissomlyó in Hungary (e.g., [89]); the Udo, Songaksan, and Yangpory in South Korea (e.g., [8,54,90]); the Purrumbete Maar in Australia (e.g., [10]); Fekete-hegy [91], Bondoró [31], and Tihany [29] from the BakonyBalaton Highland Volcanic Fields in Western Hungary; some maars in the Eifel volcanic field, Germany [92,93]; the Cerro Negro scoria cone, Nicaragua [94,95]; and El Volcancillo, Mexico [96]. All of these examples were likely constructed over a longer period of time (from Ky to My).…”

“…However, the reality is different and that is what this book chapter tries to demonstrate. For instance, increasing investigations in several volcanic fields have shown that small volcanoes can exhibit, in special cases, a contrasting stratigraphy consisting of tephra units and other lava flows sometimes of different geochemical compositions (e.g., [8][9][10]). The eruptive units are sometimes deposited periodically with short or even prolonged inactive periods between eruptive events, indicating an evolution that cannot be explained with a single eruption (e.g., [11][12][13]).…”

“…In this chapter, we intend to explore this diversity through some recent studies and own research. Examples will include recently documented small volcanoes showing complex stratigraphy, compound volcano edifice, and complex eruptive history, in various volcanic fields, including the Western Australian volcanic field (e.g., [10,20]), the Coli Albani volcanic complex in Italy [13,21], the Cameroon volcanic line [11,22,23], the Eiffel volcanic field [24,25], the Trans-Mexican Volcanic Belt [26][27][28], the Central Volcanic Range of Costa Rica [12], the Bakony-Balaton Highland Volcanic Field in Hungary [29][30][31], as well as Auckland volcanic field in New Zealand [32][33][34].…”

The increasing number of field investigations and various controlled benchtop and largescale experiments have permitted the evaluation of a large number of processes involved in the formation of maar-diatreme volcanoes, the second most common type of smallvolume subaerial volcanoes on Earth. A maar-diatreme volcano is recognized by a volcanic crater that is cut into country rocks and surrounded by a low-height ejecta rim composed of pyroclastic deposits of few meters to up to 200 m thick above the syn-eruptive surface level. The craters vary from 0.1 km to up to 5 km wide and vary in depth from a few dozen meters to up to 300 m deep. Their irregular morphology reflects the simple or complex volcanic and cratering processes involved in their formation. The simplicity or complexity of the crater or the entire maar itself is usually observed in the stratigraphy of the surrounding ejecta rings. The latter are composed of sequences of successive alternating and contrastingly bedded phreatomagmatic-derived dilute pyroclastic density currents (PDC) and fallout depositions, with occasional interbedded Strombolian-derived spatter materials or scoria fall units, exemplifying the changes in the eruptive styles during the formation of the volcano. The entire stratigraphic sequence might be preserved as a single eruptive package (small or very thick) in which there is no stratigraphic gap or significant discordance indicative of a potential break during the eruption. A maar with a single eruptive deposit is quantified as monogenetic maar, meaning that it was formed by a single eruptive vent from which only a small and ephemeral magma erupted over a short period of time. The stratigraphy may also display several packages of deposits separated either by contrasting discordance surfaces or paleosoils, which reflect multiple phases or episodes of eruptions within the same maar. Such maars are characterized as complex polycyclic maars if the length of time between the eruptive events is relatively short (days to years). For greater length of time (thousands to millions of years), the complex maar will be quantified as polygenetic. These common depositional breaks interpreted as signs of temporal interruption of the eruptions for various timescales also indicate deep magma system processes; hence magmas of different types might erupt during the formation of both simple and complex maars. The feeding dikes can interact with groundwater and form closely distributed small craters. The latter can coalesce to form a final crater with various shapes depending on the distance between them. This observation indicates the significant role of the magmatic plumbing system on the formation and growth of complex and polygenetic maar-diatreme volcanoes.
